The Problem
CNC woodworkers and cabinet makers spend hours in spreadsheets calculating sheet usage, cut sequences, and material waste before they touch a machine. Enterprise cabinet software costs thousands of dollars and assumes you have a production floor. Nothing existed for the maker, the small shop, or the serious hobbyist.
The Solution
KerfOS is a browser-based cabinet design tool that generates cut lists, optimizes sheet usage across multiple panels, and exports G-code directly for any CNC router — no backend dependency, no account required to start. It models the real workflow of someone standing in front of a sheet of plywood.
KerfOS is purpose-built for the hobbyist shop and small cabinet maker — the people who have been using spreadsheets and generic CAD tools because nothing else was made for them.
Built with Next.js and TypeScript. G-code generation runs client-side — no server, no subscription required to get a cut file.
