STEP parsing is executed client-side via OpenCascade compiled to WebAssembly inside a Web Worker — that’s the clever move: no uploads, responsive UI, and better privacy. The app nails the basics (drag & drop, multi-file tabs, wireframe/ortho toggles and one-click share links), so it solves a real, annoying workflow problem for people who just want to eyeball parts. The interface is clean and functional, though sharing expiration and missing desktop release are small frictions.
