Show HN: Web-based 2D geometry calculator

ccorcos Wednesday, September 17, 2025

I often find myself trying to solve a geometry problem where the constraints are really simple to understand, but solving it algebraic is really hard and tedious.

I built this whole thing from scratch with Claude Code. It's my first time trying it and I literally did not write a single line of code...

That said, it still would be hard build this as a novice. I had to guide things along the happy path, but it saved me a ton of time!

The code is open source! Let me know if you run into any issues.
