Hooks into running Three.js scenes via a Chrome DevTools bridge and exposes 59 tools for live inspection and modification. Works with vanilla Three.js, React Three Fiber, or any framework without code changes. Starts a browser at localhost:9222 with an injected WebSocket bridge that lets you query the scene graph, edit materials and shaders, toggle lights, monitor performance and memory, preview objects in 3D, and generate React components from GLB files. Includes an in-browser overlay with live stats and an interactive scene editor. Useful when debugging rendering issues, tweaking materials without restarting, or hunting down performance bottlenecks in existing projects. Keep the browser tab open while using it or the WebSocket drops.
