Best Nesting Software in 2026 — Compared (Free & Paid)
A complete comparison of the best nesting software in 2026: Deepnest, SVGNest, ProNest LT, MyNesting, Lapas, and more. Find the right tool for your laser, plasma, or CNC workflow.
If you cut parts from sheet material — steel, plywood, acrylic, fabric — you need nesting software. But with dozens of options ranging from free and open-source to $10,000+ enterprise licenses, choosing the right one is not straightforward.
This guide compares the best nesting tools available in 2026 across key criteria: pricing, deployment (browser vs. desktop), file format support, output formats, and who each tool is best for.
What is nesting software?
Nesting software automatically optimizes the placement of parts on a sheet material to minimize waste. It solves the 2D irregular bin packing problem — finding the arrangement of parts that uses the least number of sheets while fitting all required quantities.
The difference between a good and bad nesting solution can mean the difference between 65% and 90% material utilization — on a shop spending $5,000/month on steel, that’s a $1,250 monthly difference.
The tools compared
1. Lapas — Best browser-based option
Price: Free tier / $49/month Pro
Deployment: Browser (no install)
Best for: Laser cutting shops, plasma CNC, sheet metal, woodworking
Lapas is the only nesting tool that combines browser-based access, a free tier, and live real-time nesting preview. It accepts DXF and SVG files, supports true-shape irregular nesting, and exports to DXF, G-code, PLT, and PDF.
Pros: No install, works on any OS, live preview, transparent pricing, DXF/G-code/PDF output, free plan
Cons: Newer product than desktop alternatives; no offline mode
2. Deepnest — Best free offline option
Price: Free (open source)
Deployment: Windows / macOS desktop (download required)
Best for: Hobbyists, makers, low-volume laser shops
Deepnest is the most well-known free nesting tool — but it has not been maintained since 2021 (last release: v1.0.5). It performs true-shape nesting using a genetic algorithm, supports DXF and SVG input, and outputs DXF/SVG.
Pros: Completely free, no account required, good nesting quality for simple jobs
Cons: Abandoned since 2021, no G-code export, no browser version, no project history, Windows/Mac only

3. SVGNest — Best browser-based free option
Price: Free (open source)
Deployment: Browser
Best for: Hobbyists, SVG workflows, LightBurn users
SVGNest is browser-based and requires no installation, which is its main advantage over Deepnest. It’s integrated into some LightBurn workflows. However, it only accepts SVG input (not DXF), and the project has not been updated since approximately 2016.
Pros: Browser-based, free, no install, academically well-documented algorithm
Cons: SVG only (no DXF), effectively abandoned, no support, no export to G-code or PDF
4. ProNest LT — Best for Hypertherm users
Price: $29.99/month (Essentials), 7-day free trial
Deployment: Windows desktop (download required)
Best for: Shops using Hypertherm plasma cutters
ProNest LT is Hypertherm’s entry-level nesting product. Its strongest differentiator is SureCut™ technology — True Hole®, Rapid Part™, and PlateSaver™ — which are hardware-specific optimizations only available with Hypertherm machines. If you don’t use Hypertherm hardware, these features are irrelevant.
Pros: Good nesting quality, free trial, Hypertherm hardware integration, trained support
Cons: Windows-only, no browser version, no free plan after trial, extra seats cost $200+/year
5. MyNesting — Best international option
Price: $49/month
Deployment: Browser + Windows desktop
Best for: International users, repeat-part workflows
MyNesting is a cloud-based nesting tool with strong international presence (their testimonials page shows users across 20+ countries). It has a browser version and a desktop version. The main friction point is that a free trial requires a credit card.
Pros: Browser-based, good nesting quality, international support, parts library for repeat jobs
Cons: Credit card required for trial, pricing can be confusing ($25/day vs. $49/month)
6. SigmaNEST — Best enterprise option
Price: Quote only ($5,000–$20,000+/year)
Deployment: Windows desktop
Best for: High-volume fabrication shops, MES/ERP integration
SigmaNEST is the most comprehensive nesting platform — combining nesting, CAM, shop floor management, and ERP integration in one. It’s been around for 25+ years and supports 7+ cutting processes and hundreds of machine brands.
Pros: Extremely comprehensive, 25 years of development, ERP/MES integration
Cons: Quote-only pricing (no transparency), no free plan or trial, enterprise cost, no browser version

How to choose
- I want completely free, no limits: Deepnest (but it’s abandoned and Windows/Mac only)
- I want browser-based and free to start: Lapas
- I use Hypertherm plasma cutters: ProNest LT
- I run a high-volume fabrication shop needing ERP integration: SigmaNEST
- I’m a hobbyist with an SVG workflow: SVGNest
Bottom line
In 2026, the best nesting software for most cutting shops is one that is browser-based (no install, any OS), has a free tier (evaluate with real jobs), and supports DXF input with G-code or DXF output. Lapas is currently the only tool that meets all three criteria.
