Free tools for people who cut their own glass
Each one does a single job properly and opens in a browser tab. No sign-up, no install, nothing to learn first.
Whatever you open stays on your own machine — the measuring happens right there in the browser.
Stained glass pattern checkerfree
Numbers every piece in your pattern and flags the ones that will fight you: too small to hold, too narrow to survive, an inside curve no grinder head is getting into, or an inside corner a score simply cannot turn. Totals the glass you need per colour, and prints the whole thing at true size.

The bench is new. If this one saves you an afternoon, the next will be for the same kind of work — tell it what you're stuck on and it may well be the one that gets built.
Why it's free
A tool nobody can try is a tool nobody uses. The checkers stay free, always. If these turn out to be worth keeping, the paid part will be the things you only want once you rely on them: saving projects, working across several panels, exporting cut lists.
Why nothing gets uploaded
Your patterns are your own designs. There is no reason for them to sit on someone else's server, so they don't — everything is measured in your browser and nothing is sent anywhere.
