GB Nest exists to close the gap between free open-source nesters and enterprise software costing thousands per seat.
There's a frustrating gap in the nesting software market. At the top end, enterprise nesting suites cost thousands per seat with annual maintenance fees. At the bottom, free open-source tools do the basics but typically lack persistent caching, hole nesting, DWG support, or the kind of optimisation refinements that academic literature has known about for fifteen years.
GB Nest closes that gap. A real No-Fit-Polygon contour engine. A multi-threaded genetic optimiser with adaptive rotation and memetic local search. Hole nesting that packs small parts inside the holes of larger ones. All as a single Windows EXE you can download, unzip, and run - for an affordable monthly subscription.
Real algorithms from academic nesting literature - PMX crossover, memetic local search, adaptive rotation - implemented properly. Not marketing.
Two tiers. Real prices on the website. No "contact sales for pricing" theatre. No annual maintenance fees. No surprise upcharges.
A single Windows EXE. No Electron, no .NET, no installer. Runs from a USB stick if you want. Starts in under a second.
Projects live on your computer. Cancel any time and your files keep working. No cloud lock-in, no held-hostage data.
The Genetic Optimiser has a hard wall-clock budget. Set 60 seconds; get a result in 60 seconds. No mystery runs.
Support emails go to people who know the codebase. Bug reports often turn into fixes in the next release.
GB Nest is built and supported by a small team based in the UK. We share one priority: shipping a tool that workshops actually want to use. Because we're small, we can move fast - feature requests don't disappear into a backlog black hole.
