Top Sheet Metal Cutting Software for Nesting Optimization (Desktop, Online & Mobile)

Introduction

Sheet metal cutting optimization—often achieved through nesting software—arranges parts on flat metal sheets or coils to maximize material usage and reduce scrap. In industries like architectural metal fabrication and construction, even a small improvement in sheet utilization can yield significant cost savings. For example, reducing scrap from 10% to 8% in a shop using 50 metal sheets per week could save around $16,000 over three years. Advanced nesting algorithms can boost material utilization by 5–20% compared to manual layouts or older software, translating into higher yields and lower material waste. In fact, some intelligent nesting systems report material usage improvements of up to 15%. The following is a categorized list of sheet metal cutting software—from powerful desktop applications and convenient online SaaS tools to on-the-go mobile apps—designed to optimize flat sheet nesting for CNC cutting operations. Each program listing includes a brief description, key features, pros and cons, pricing (free or paid), and notes on industrial use (e.g. architectural and construction sheet metal work such as Mehbud’s fencing, façade, and ceiling profile production).

Desktop-Based Sheet Metal Nesting Software

3. Cons: Being a full CAD/CAM system, it is not lightweight—smaller fabricators might find it more than they need; user interface is dense and may require training to master; pricing is on the high side (similar to other enterprise nesting systems) and typically sold via dealers; primarily Windows-based. Not targeted to hobbyists, and there’s no free version (only demos). 
4. Free or Paid: Paid – Commercial software. Interested users must contact Lantek for a quote or demo. It’s usually sold as a license per module (e.g. you buy cutting module, punching module, etc.) with annual support contracts. No free edition, but its robust features are geared towards professional manufacturing environments. 

NestFab (Paid)

Description: NestFab is a dedicated automatic nesting software developed by Efficient Software Ltd. Unlike full CAD/CAM suites, NestFab focuses purely on optimized layouts. It’s known for a modern GUI and extremely efficient nesting engine. NestFab gained attention for its “Ultra Performance” nesting option, which delivers exceptional material utilization results. This software is often used to supplement existing CAD/CAM workflows by providing a better nesting solution that can export nests back to your cutting machine or CAM software.

1. Key Features: True-shape automatic nesting with continuous optimization (it keeps improving the layout until stopped); part-in-part nesting (places smaller parts into the voids of larger parts); supports irregular sheet shapes and remnants; imports common 2D formats (DXF, DWG, etc.) and outputs nested DXF or compatible formats for CNC; Ultra Performance engine that leverages multi-core CPUs and advanced algorithms to tighten nesting – it can reduce material usage by 10–25% compared to the standard engine; batch nesting of multiple job files; configurable priorities and constraints (e.g. part rotation limits, quantity to produce, sheet size selection). 
2. Pros: One of the highest nesting efficiency tools on the market – users report material savings of 5–20% over results from other software when using NestFab’s Ultra mode; straightforward interface focused on nesting (minimal learning curve compared to CAD-heavy systems); offers a 7-day free trial and a relatively affordable entry price for the standard version, making it accessible for smaller businesses; fast computation—finds good solutions within seconds for typical jobs, and you can let it run longer for incremental improvements. Great for manufacturers needing to maximize sheet yield (e.g. metal fabrication shops where raw material cost is a big concern). 
3. Cons: Limited to nesting functionality – you’ll still need other software for CAD design and for generating CNC cut paths (NestFab provides the layout but not machine-specific cutting instructions or toolpath optimization); the Ultra Performance feature costs extra, increasing the price if you need top efficiency; lacks some advanced CAM features (no built-in cutting simulation or detailed machining parameters, since it assumes you’ll handle that elsewhere); currently Windows-only. 
4. Free or Paid: Paid – Offers a free trial (full-featured for 7 days). After trial, requires license purchase. Pricing is generally lower than big CAD/CAM suites, appealing to small and mid-size shops. No free tier beyond the time-limited demo. The investment can pay off through material savings if you regularly cut a high volume of sheet metal. 

Deepnest (Free & Open Source)

Description: Deepnest is an open-source nesting application available for Windows, Mac, and Linux. It’s a free tool popular among hobbyists, makers, and smaller fabrication businesses. Despite being free, Deepnest employs sophisticated algorithms (genetic algorithm based) to pack parts tightly. It’s great for laser cutting, CNC routing, or waterjet jobs where you need to nest various shapes without the budget for commercial software.

1. Key Features: True shape nesting with support for DXF, SVG, and CorelDRAW (CDR) file import; automatic common-line merging (overlapping adjacent part edges so the machine cuts once, saving time and reducing waste); part-in-part nesting (places smaller cut pieces within holes of larger parts to utilize dead space); configurable gap settings, rotation increments, and quantity per part; continuous optimization – Deepnest will keep searching for a better layout until you stop it, allowing you to balance speed vs. thoroughness; outputs in DXF/SVG for easy loading into CAM software or directly to machines that accept those formats. 
2. Pros: Completely free to use (no licenses, and even the source code is available); cross-platform compatibility; fairly easy to get started with a simple interface and a quickstart guide; achieves significant material savings for complex laser cut projects by using advanced nesting logic (comparable, in some cases, to commercial solutions); supports merging of cut lines which not all nesting tools (especially low-cost ones) can do, improving efficiency and part quality by avoiding duplicate cuts. Ideal for small shops, startups, or educational use where budget is limited but optimization is desired. 
3. Cons: Performance can be slower for very large or complex nesting jobs compared to commercial optimized solvers – you might need to let it run longer to reach the optimal result; lacks direct machine post-processing (you get a DXF of the nest, then must use another CAM program for toolpaths and G-code); the user interface, while simple, is not as polished or feature-rich (for example, no built-in cost calculator or inventory management); support is community-based (GitHub forums) so troubleshooting relies on user community. Also, since it’s free, there is no official support line if something goes wrong. 
4. Free or Paid: Free – Deepnest is open-source and free of charge. Users can donate to the developer optionally (previously it was “pay what you want,” now it’s freely downloadable). This makes Deepnest an attractive option for individuals or companies that want to experiment with nesting optimization without financial commitment.
   

Online SaaS Nesting Software

Online SaaS (Software as a Service) solutions for sheet metal nesting run in the cloud or directly in a web browser. They require no heavy local installation, making them convenient for cross-platform access (Windows, Mac, tablets, etc.) and collaboration. These cloud-based nesting optimization tools often offer subscription models and let you upload part geometries (DXF, etc.) to get optimized sheet layouts. They are scalable and kept up-to-date by the provider, and some provide APIs for integration into your workflow. Below are notable online nesting services:

Nest&Cut (Paid SaaS with Free Trial)

It’s geared toward manufacturers, small businesses, and even machine builders who want to offer a simple nesting solution to their clients.

1. Key Features: Web-based interface accessible from any modern browser; imports DXF/DWG and cleans/prepares geometry automatically for nesting (e.g., it can fix minor drawing issues); fast Powernest algorithm that considers various constraints to maximize efficiency (marketed as “the world’s best algorithm” for nesting); outputs nested layouts as DXF files, PDF reports, or even NC code for cutting machines (it includes basic CAM functionalities like adding lead-ins); supports parametric parts and batch processing (helpful if you cut similar shapes with different sizes); available in multiple languages. The service also includes essential CAM features, such as generating cutting paths and simulating NC code, so it can act as a lightweight all-in-one nesting + cutting solution in the cloud.
2. Pros: No installation required and works on various devices; intuitive UI – you can get results in just a few clicks, making it accessible to non-experts; continually updated on the server side (improvements roll out without user effort); great for on-demand usage – e.g., if you occasionally need nesting, you can use it when needed rather than maintaining expensive software; 30-day free trial to evaluate its effectiveness; suitable for small and medium manufacturers looking for efficient nesting without investing in heavy software infrastructure. Also attractive to machine manufacturers or resellers as it can be offered alongside machines for a turnkey software solution.
3. Cons: Being cloud-based, an internet connection is required and there may be concerns about uploading proprietary designs to a third-party server (data security); performance for extremely large jobs depends on server capacity and your internet speed (though generally cloud computing power is ample); it operates on a subscription model, which can accumulate cost over time – pricing starts around $59/month for a basic plan, which might be high if you only nest occasionally. Additionally, while it has CAM features, they are “essential” – advanced users might find it lacks some fine-tuning options available in desktop CAM software.
4. Free or Paid: Paid SaaS – Nest&Cut is subscription-based. The Classic plan is about $59/month (with discounts for annual payment), and a higher-tier Production plan exists for larger needs. All plans allow unlimited nesting during the subscription and come with a free trial period. Once the trial expires, continued use requires payment. This service is best for companies that want a professional nesting tool without managing local software, and who are comfortable with a recurring payment model.

Nesting Center (Freemium SaaS)

Description: Nesting Center is an online nesting system and API, offering “nesting layout calculation services” via the web. It’s optimized for various cutting industries (sheet metal, textiles, wood, etc.) and provides true-shape nesting through a browser interface or via API calls. Nesting Center emphasizes quality of nests, speed (quick initial results that refine over time), and flexibility (it can be used as a web app or integrated into other software via API).

1. Key Features: True-shape nesting for parts of any shape on rectangular or custom-defined sheet sizes; also supports guillotine sawing mode for panel cutting with only straight cuts; common-line nesting mode for profile cutting to minimize shared edges; cloud-based solver that delivers a first nesting solution within seconds and then iteratively improves it; material management features to choose optimal sheet sizes and quantities based on availability (useful for estimating stock needed for a job); API access allowing developers to send nesting requests from their own software systems and get results programmatically. It supports uploading parts via DXF/DWG or by using a web form.
2. Pros: Offers a free tier – you can try it with up to 50 parts per nest at no cost, making it very accessible for small jobs or evaluation; clear pricing tiers for higher usage (e.g., Basic and Professional subscriptions for larger part counts or unlimited usage); high-quality nesting results with support for irregular shapes (suitable for laser/plasma cutting complex profiles); versatile – one platform handles both true-shape CNC nesting and simpler rectangular panel cutting, which is great if your shop does multiple types of cutting; API integration is a big plus for companies that want to incorporate nesting into their custom software or workflow (for example, a fabrication ERP system could call the Nesting Center API to optimize layouts automatically).
3. Cons: The web interface, while functional, may not be as feature-rich as desktop software – for instance, editing a nest or manually adjusting it might be limited compared to a full CAD/CAM program; dependency on internet and cloud service availability (any downtime or slow network will impede usage); although there is a free tier, it has limits (50 parts, and presumably no DXF export unless you subscribe – based on feature differences like DXF export being mentioned for premium users); cost for Professional tier (~€590/year) is reasonable for businesses but still an ongoing expense. Users handling extremely sensitive designs might prefer an on-premise solution for data control, though Nesting Center does ensure privacy.
4. Free or Paid: Freemium/Paid – Free for small nests (up to 50 parts), which is great for prototypes or occasional use. Paid plans: Basic (€99/year) and Professional (€590/year) with higher limits or unlimited usage. This tiered approach allows you to scale up as your needs grow. The free option makes Nesting Center an attractive starting point for anyone new to nesting software.

MyNesting (Freemium SaaS)

Description: MyNesting is a unique online nesting service that provides automatic layout optimization without upfront software costs. You download a lightweight program to prepare and upload your parts, then the nesting computation is done in the cloud. MyNesting pioneered a pay-as-you-go model, ideal for small businesses or hobbyists: you can use the nesting tool for free and only pay when you want to download a finished nest layout.

1. Key Features: True-shape nesting engine running on the cloud (no heavy processing on your PC); simple interface to import parts (commonly via DXF) and specify sheet size/quantity; allows setting part counts and spacing; returns an optimized nest that you can preview. If you’re satisfied, you can purchase the output DXF file of the nested layout. There’s also an option for an unlimited-use desktop version if you prefer one-time purchase. The service supports multiple languages and has tutorial videos to help new users.
2. Pros: No subscription required – you pay per result as needed, which can be very cost-effective if you only occasionally need nesting; very low barrier to entry: the software is free to try, and the first nest output is free as a trial, so you can see the benefits before spending anything; automatic nesting quality is quite good for a cloud service (developed by Efficient Software, the makers of NestFab, so it inherits a strong nesting algorithm background); great for small workshops, makers, or educational purposes where buying a full software license isn’t justified; by being cloud-based, it offloads heavy computations, meaning even a basic computer can handle large nesting jobs via MyNesting.
3. Cons: Pay-per-nest costs can add up if you use it very frequently (at $5–$7.50 per nest file as of recent info), in which case a subscription or licensed software might become cheaper; requires internet and the workflow involves using their application to connect to the service – slightly less straightforward than purely offline software; feature set is relatively basic (it focuses on nesting only, without advanced editing, CAD drawing, or machine-specific cutting parameters). Also, being a smaller service, user community and support are not as extensive as some major vendors.
4. Free or Paid: Freemium – The software download and nesting process are free to use, you only pay when you want to export the optimized nest as a DXF. The first export is free, afterwards it’s a pay-per-download model (with bulk credit packages available to reduce cost per nest). For heavy users, an unlimited version can be purchased which then allows unlimited nests without per-file fees. MyNesting’s model is especially appealing to those who need a quality nesting solution on an infrequent or project-by-project basis.

Optimalon 2D Cutting Optimizer (Free/Paid SaaS)

Description: Optimalon offers a free online panel cutting optimizer, a web application aimed at 2D rectangular cut layouts (also known as guillotine cutting). While not specific to irregular shapes, this tool is very useful for sheet metal operations that involve cutting rectangular blanks (e.g., HVAC ducts, rectangular panels for construction) from standard stock sheets or coils. It’s essentially a cloud-based version of the well-known Cutting Optimization Pro algorithm for panel cutting.

1. Key Features: Runs entirely in your browser—no installation needed; optimizes rectangular cuts on stock sheets with support for different cutting complexity levels (straight cuts in one direction, two-stage cuts, etc., depending on your machine’s capability); accounts for saw blade or cutter kerf (cut thickness), trim cuts, and any machine-specific constraints like one rotation limit; allows multiple stock sheet sizes and will choose the best mix of sheets to fulfill your parts requirement; stores projects on the cloud so you can access them from anywhere when logged in; outputs cutting layouts as graphical images (free version) or DXF/Excel reports for premium users.
2. Pros: Completely free for basic use – you can optimize panel layouts without paying, which is helpful for occasional needs; because it’s optimized for guillotine (saw-like) cutting, it guarantees feasible cut sequences for sheet metal shearing or straightforward cutting operations; accessible from any device (including tablets) due to its web nature; handles multiple materials and thicknesses in one project if needed (good for planning across different sheet stocks); provides useful stats like used area vs waste and number of cuts in the layout image. This tool can improve material yield for rectangular nesting significantly over manual layout, which in some cases is critical (e.g., optimizing coil cuts to reduce scrap).
3. Cons: Only works for rectangular or linear cuts – it cannot nest arbitrary shapes or curves (so not suitable for profiling intricate parts; those require true-shape nesting software); the free version limits output capabilities (no DXF export unless you upgrade to premium); lacks advanced features beyond layout computation (no cost calc, no CNC machine code output – it’s up to you to interpret the layout into machine instructions); the interface is utilitarian and not as modern as some other web tools. Also, it requires a constant internet connection and saving projects on their server might raise security policy questions for some companies (though the data is just dimensions, not detailed CAD).
4. Free or Paid: Free and Paid – The core panel optimizer is free online, with options to register for saving projects. Premium subscription unlocks additional features like DXF export, Excel reports, and CNC saw compatibility outputs. The cost for premium is relatively low compared to full CAD software, and you only need it if those extra outputs are required. Overall, Optimalon’s solution is a handy web app for anyone cutting sheets into rectangles, including sheet metal shops doing simple cut-to-size operations.

SVGNest (Free Open-Source Web Tool)

Description: SVGNest is an open-source vector nesting tool that runs in the browser. It’s essentially a demo or library, but an online demo is available at svgnest.com which allows you to perform true-shape nesting of SVG format parts. It’s completely free and showcases advanced nesting features like part-in-part and concave shape detection. While not a polished commercial service, it’s a noteworthy mention for those interested in a free, no-install solution for irregular shape nesting.

1. Key Features: Browser-based automatic nesting of any SVG shapes; part-in-part nesting (can place smaller shapes in the hollows of larger shapes, improving utilization); can handle rotation of parts and even detect concave areas to tuck parts into tight spaces; runs purely on client-side JavaScript (after loading, it uses your computer’s CPU, so your design isn’t uploaded to a server – a plus for privacy, though heavy jobs tax your browser); adjustable spacing and iteration count; visual display of how parts are being shuffled and placed. Being open-source, developers can tweak the code or integrate it into other web applications.
2. Pros: Completely free and no login or subscription – just go to the website and start nesting; surprisingly capable for an in-browser tool, handling complex shapes and delivering decent pack efficiencies that rival basic commercial solutions; since it’s open-source, it’s a learning tool for those curious about how nesting algorithms work or for companies that might want to build a custom nesting solution into their software via the library; no need to install anything – works on any device with a modern browser (though a PC is recommended due to processing needs).
3. Cons: The user interface is minimal and can be confusing at first; it only accepts SVG format directly – you may need to convert your DXF files to SVG to use it, which is an extra step; performance depends on your device – large numbers of parts or very complex shapes can slow down or crash the browser since it’s using your local resources; it does not generate CNC-ready output like G-code or even DXF – you get an SVG layout which then might need conversion to DXF for manufacturing; no dedicated support or guarantee of updates (it’s a volunteer project). Essentially, SVGNest is more of a nifty tool or a starting point for experimentation, rather than a full production-ready SaaS for industry use.
   
4. Free or Paid: Free – It’s open-source (MIT license) and the online demo is free to use. There are no paid plans. If you have very occasional nesting needs or want to nest without installing software, SVGNest is an option, but for regular industrial use, one of the more supported tools above would be preferable.

Mobile Applications for Sheet Cutting Optimization

Mobile apps bring nesting optimization tools to smartphones and tablets, useful for quick calculations on the shop floor, field work, or small projects. While mobile apps may not be as powerful as desktop or cloud software for complex true-shape nesting, they excel at simplifying cutting plans for panels or basic shapes on the go. They often cater to woodworkers and DIY enthusiasts as well, but many support metal, glass, or other sheet materials. Here we list some notable mobile apps (Android and iOS) for flat sheet cutting optimization:

CutList Optimizer (Android & Web – Freemium)

Description: CutList Optimizer is a popular mobile app (Android) and web app for panel cutting optimization. It generates cutting patterns for rectangular parts from sheets by nesting them efficiently. Despite being known in woodworking, it supports metal and other materials as well, making it handy for sheet metal fabricators needing to optimize cuts of rectangular blanks or panels. Your projects can sync between the Android app and the online web version, providing flexibility in where you work.

1. Key Features: Easy input of panel stock (multiple sheet sizes, quantities) and list of parts with dimensions; supports different measurement units (imperial, metric, including fractional inches); accounts for kerf (blade or cutter width) and can enforce grain direction or pattern direction in cuts; edge banding allowance feature (useful for woodworking, but also for metal if edge trimming needed); can export cutting diagrams to PDF or images for reference; saves data to cloud so your phone and web browser share projects. The app computes an optimized layout to minimize waste or optionally minimize the number of sheets used. 
2. Pros: Extremely user-friendly – within minutes you can input your cut list and get a layout; the mobile app means you can calculate material needs on-site or in the workshop without a PC; widely used and actively updated (over 1 million downloads, indicating a strong user base and feedback loop); for sheet metal businesses that often cut rectangular pieces (e.g., signage backings, panels, standard blanks), this tool can reduce scrap significantly and improve yield; basic use is free, which covers many scenarios; the synchronization between web and mobile is convenient for updating cut plans from an office computer and then accessing them on the shop floor via phone. 
3. Cons: Focused only on rectangular cuts – it will not help with arbitrary shaped parts nesting; the free version includes ads and may have limits on the number of cut lists you can save or size of projects (premium version removes ads and unlocks unlimited projects and perhaps more advanced settings via in-app purchase); it does not output CNC machine code – it’s intended for you to manually follow the cut layout or input it into another software; complex inventory scenarios (like reusing off-cuts) are not automated, though you can manually add leftover pieces as stock panels. Also, being a mobile app, it may not handle extremely large numbers of parts as comfortably as a desktop solution due to memory constraints. 
4. Free or Paid: Freemium – The Android app is free to download and use with some feature limitations and advertisements. An optional Pro upgrade (in-app purchase or subscription) unlocks full capabilities (such as unlimited saved projects, no ads, and possibly priority support). The web version also offers a Pro subscription. Even with the paid upgrade, CutList Optimizer is relatively low cost, making it a cost-effective tool for improving material usage in small-scale operations. 

SketchCut (Android – Free/Paid)

Description: SketchCut is a mobile app (Android) designed for calculating and optimizing cutting layouts for sheet materials. It’s commonly used for woodworking (plywood, MDF), but equally applicable to sheet metal, glass, plastic, etc., as it deals with rectangular cutting plans. SketchCut comes in two versions: Lite (free) and PRO (paid). The app allows users to enter sheet dimensions and required part sizes, then it produces an optimized cutting diagram.

1. Key Features: Multiple sheet sizes and materials can be managed in a single project; supports edge trimming settings and saw blade thickness; optimization settings to prioritize either minimal waste or easier cutting (fewer cuts); the PRO version enables saving unlimited projects and offers more layout options, while the Lite version might limit number of cuts or parts; generates cut diagrams with different colors or labels for parts for clarity. It also can export the layout image or cutting plan report. The interface is straightforward with input tables for stock and parts. 
2. Pros: Fast and convenient for on-the-go calculations – you can figure out how to cut a metal sheet into pieces right on your phone or tablet; the free version suffices for small projects and lets you test the app’s effectiveness; PRO version is a one-time purchase (typically inexpensive, around $10) and unlocks full functionality without ads, which many users find worthwhile; helps reduce errors in planning cuts by clearly illustrating the cutting order; good for shops that do lot cutting of standard shapes (e.g., rectangular HVAC duct panels, simple base plates) – it ensures you get the most out of each sheet or coil segment; works offline, so you can use it in the workshop where internet might not be available. 
3. Cons: Like other panel optimizers, it cannot handle non-rectangular part shapes; no true-shape nesting or CNC toolpath output – this is primarily for manual or semi-manual cutting guidance; screen size on a phone can be a limiting factor for viewing detailed cut diagrams (though zooming is available); the app’s development and updates are a bit slower in recent years, and support is informal (via email or app store reviews). Also, it may not consider more advanced constraints like different grain orientation per piece (unless you manually separate those as different materials). 
4. Free or Paid: Both – SketchCut Lite is free with some limitations. SketchCut PRO is a paid app (one-time cost) that unlocks all features and removes ads. The cost is relatively low, and there is no recurring fee. This makes SketchCut PRO an affordable tool for small workshops or independent contractors who frequently need to optimize cut layouts without investing in bigger software. 

iOptiCut (iOS – Paid)

Description: iOptiCut is a cutting optimizer app for iPhone/iPad that focuses on 2D sheet and linear material cutting. It’s essentially the iOS counterpart for panel optimization similar to CutList/SketchCut. With iOptiCut, users can define sheet stock and required rectangular parts, and the app computes an optimal cutting plan. It’s marketed for wood, glass, metal, drywall, and other materials that come in panels or bars. This app is a handy tool for iOS users (contractors, fabricators, project managers) to plan cuts and estimate material needs on site.

1. Key Features: Handles both sheet (2D) and linear (1D) optimization – so it can optimize cutting of metal sheets as well as things like rebar or pipes by length; for sheet mode, you input sheet dimensions and part sizes/quantities, and it will produce one or multiple cutting layouts to fit all parts; supports different priorities (minimize waste or maybe minimize cuts); provides a detailed cut order and diagram on-screen; can output or share results (the app description mentions generating and displaying complex layouts and cutting instructions instantly); allows managing different materials and cutting projects in the app. 
2. Pros: One of the few dedicated iOS apps for cutting optimization – convenient for iPhone/iPad users since many nesting apps are Android or web-based; covers both 2D and 1D cutting problems, increasing its utility (e.g., a metalworking firm could optimize sheet metal cuts and also optimize cutting of stock lengths like profiles or pipes using one app); does not require internet – all computation is on the device, so you can use it in remote job sites; provides quick estimates of how many sheets are required for a job and how to cut them, which can aid in quoting and planning; the interface is tailored for mobile use with simple forms and results that are easy to interpret. 
3. Cons: Paid app with no free trial, so users must purchase (around $8–$10) upfront – however, this is a modest cost compared to PC software; limited to rectangular pieces for optimization; performance is constrained by your device’s processing power – very large projects (hundreds of pieces) might be slow or not feasible on a phone; it’s a standalone app, meaning it doesn’t integrate with other software or CNC machines directly – it’s mainly for reference and manual implementation of the cut plan. Additionally, since it’s not as widely used as some other apps, updates might be infrequent and the support community is smaller. 
4. Free or Paid: Paid – iOptiCut is a commercial app on the Apple App Store (no free version). The purchase gives lifetime use. For professionals who use iOS devices and regularly need panel cutting layouts, the cost is easily justified by the material saved and cutting time reduced. Just be aware it’s an Apple-specific solution. 

Cutting Optimizer (Android – Free with Ads)

Description: Cutting Optimizer (sometimes labeled as “Cuter Optimizer” in the app description) is an Android app designed to optimize cutting plans for various materials, mentioning glass and aluminum among others. The app allows users to select a stock sheet size and input desired cut dimensions, then it computes an optimal plan to minimize waste. It appears to target both hobbyist and professional use for quick cutting estimates.

1. Key Features: Simple input interface for one stock “mother” sheet and multiple part sizes; generates an optimized layout with a list of cut pieces and their placements; highlights unused material; supports materials like glass and metal where minimizing scrap is important; provides a breakdown of the cut plan and possibly the remaining scrap size; the app is lightweight and focused on quick calculations. It contains in-app ads and offers in-app purchases (perhaps to remove ads or unlock more features). 
2. Pros: Quick to use for one-off cutting jobs – if you have a single sheet or standard stock and a list of pieces, it gives you an instant layout suggestion; can handle various units and is not limited to wood – explicitly suited for sheet metal or glass where precision is needed; helpful for small fabricators or installers who might need to cut sheets on-site and want to plan cuts beforehand; the app is free, so it’s an easy addition to your toolbox without any cost barrier; updated recently (as of 2025) which indicates active development. 
3. Cons: Appears to handle only one stock sheet size at a time (so if you have multiple sheets or need to calculate how many sheets to use, it might not do that automatically); likely only does rectangular cuts; lacks advanced settings and outputs – it’s a straightforward optimizer but not a full-featured nesting solution; the presence of ads can be a bit distracting, and the UI might be less polished due to being ad-supported; not as well-known as CutList Optimizer, hence a smaller user base and less online help available.
   
4. Free or Paid: Free (with ads) – The app can be downloaded free from Google Play. It contains ads and possibly some limitations. The developer likely offers an in-app purchase to remove ads or unlock premium functionality, but the core usage (for basic cut optimization) does not require payment. This makes it a handy free option for those who need a quick cut layout on Android and don’t require the bells and whistles of more established apps.

Conclusion

Optimizing flat sheet metal cutting is a crucial step for manufacturers and fabricators aiming to reduce waste, save costs, and improve production efficiency. The tools discussed above—spanning desktop software, online SaaS platforms, and mobile apps—provide a range of options suitable for different scales and needs. High-end desktop programs like SigmaNEST, ProNest, and Lantek Expert offer comprehensive solutions integrating with CNC machines and enterprise workflows, delivering powerful nesting algorithms that can increase material yield by several percentage points (which is significant in mass production). These are well-suited for companies with heavy throughput and complex operations, such as architectural metal panel manufacturers or industrial sheet metal fabricators. Mid-range and niche solutions like NestFab demonstrate that specialized nesting engines can further push efficiency, sometimes finding 5–15% extra material utilization beyond conventional methods—valuable for any business looking to maximize profit per sheet.

Online SaaS solutions have made nesting technology more accessible. Services like Nest&Cut and Nesting Center allow organizations to leverage advanced nesting without large upfront investments, all through a web browser. They are continually updated and can be accessed anywhere, which is great for distributed teams or remote working scenarios. Notably, they also cater to smaller operations: tools like MyNesting’s pay-per-nest model or Optimalon’s free panel optimizer mean even a one-person workshop can benefit from optimization when cutting sheet metal, without committing to expensive software. These cloud tools often come with the bonus of material inventory planning and easy scalability—features particularly useful in construction and architectural metalwork where project requirements can change and quick recalculation of cutting plans may be needed on-site.

Mobile applications further democratize sheet layout optimization, putting basic nesting capabilities in your pocket. While a mobile app can’t replace a full CAD/CAM system for intricate laser-cut parts, it shines for simpler tasks and quick estimates. An engineer or contractor at a construction site can use an app like CutList Optimizer or iOptiCut to figure out how many metal panels to order and how to cut them with minimal scrap, right from their smartphone. This kind of agility speeds up decision-making and reduces material overruns. For a manufacturer like Mehbud that produces fencing, façade, and ceiling profiles, implementing nesting optimization at various stages—from planning cuts of raw galvanized sheets to nesting patterns for CNC laser cutting—can significantly streamline production. It means fewer leftover scraps on the shop floor, more components per sheet, and ultimately a lower cost per finished product.

In summary, whether you are running an advanced fabrication plant or a small metal workshop, there is a sheet metal cutting optimization program to fit your needs. Adopting these nesting optimization tools leads to better material utilization, lower waste (contributing to sustainability goals), and improved profitability. By choosing the right mix of software—perhaps a powerful desktop suite in the engineering office, a convenient cloud service for collaboration, and a handy mobile app for field use—businesses can ensure that every sheet of metal is used as efficiently as possible. Embracing such technology is increasingly becoming a standard in the metal fabrication industry, as the competitive and environmental benefits of optimized nesting are clear and well-proven.
