Meshdiff – visually compare two STL versions in the browser, client-side

I built Meshdiff because clients keep sending me part_v3_FINAL.stl and I have no quick way to see what changed.

Drop two STL/3MF/OBJ files → voxel diff renders in your browser. Green = added material, red = removed. Adjustable tolerance (0.05–1mm). Volume delta metrics.

Privacy first: zero upload to any server. Everything runs client-side in a Web Worker.

Stack: React + TypeScript, React Three Fiber, custom voxel diff engine. No Manifold/CGAL — those assume clean CSG topology; real-world STLs are triangle soup.

If you work with 3D prints, try breaking it with your weirdest files. Real-world meshes are chaos and I need the stress test.
