Threedog.js: open-source Three.js engine lets Claude Code build, playtest and debug its own games

A developer released Threedog.js v1.3, a free MIT-licensed game engine on Three.js designed for AI coding agents like Claude Code. It handles shared systems (physics, input, saving, world streaming, gameplay) so the agent can focus on building the game. The standout feature: agents can playtest autonomously — via the engine's CLI and MCP interfaces they inspect game state, capture screenshots, run test scenarios, read structured diagnostics and fix issues themselves. It also supports WebGPU/TSL, lighting/post-processing and HLOD.
