Q3Edit - Browser-based Quake 3 map editor with WASM compilation

Show HN: Q3Edit – Edit and play Quake 3 maps in the browser

Q3Edit brings the classic Quake III Arena map editing experience directly to your web browser. Built with TypeScript and WebGL2, it allows users to open, edit, and save real .map files, featuring brushes, patches, entities, and terrain tools. Uniquely, it compiles maps using id Software's original q3map via WebAssembly and launches them instantly in browser-native ioquake3. With a Radiant-style four-view UI and no need for local game files, Q3Edit ships with OpenArena assets, making level design accessible to anyone with a modern browser.
