One URL from Preferences lets Claude Code or Codex drive FreeCAD: tree, properties, selection, views, screenshots, every command. Off until you turn it on.

Morrowind runs in a browser tab, free, on your own machine. New in 1.1.0: upload your copy once and it follows you to any computer you sign in from, saves and all. Plus multiplayer, which Morrowind never had. morrowind.virtastic.app github.com/Virtastic/op...

Spent a while getting OpenMW, the open-source Morrowind engine, to compile to WebAssembly. The full game now runs in a browser tab at 60fps, entirely client-side. Genuinely wouldn't have been possible without @emscripten.org Thank you for the toolchain. morrowind.virtastic.app @kripken.com
