SpawnForge is an AI-native, browser-based game creation platform. Describe your game in natural language and watch it come to life — or use the visual editor for fine-grained control. No downloads, no installs.
Engine: Built in Rust using the Bevy 0.18 ECS framework, compiled to WebAssembly via wasm-bindgen. The engine handles scene management, physics (Rapier 3D and 2D), rendering, animation, particles, and audio metadata — all at native speed in the browser.
Rendering: WebGPU primary (wgpu 27) with automatic WebGL2 fallback. Four binaries — two editor and two runtime variants — ensure compatibility across Chrome, Firefox, Safari, and Edge.
Editor: React shell (Next.js 16) with Zustand state management and Tailwind CSS. JSON commands flow from the editor to the engine via the wasm-bindgen bridge; events flow back through callbacks.
AI: Multi-agent orchestration with 351 MCP commands across 41 categories. AI generates 3D models, textures, sound effects, music, and voice — then uses MCP commands to place and configure them in the scene.
Traditional game engines like Unity and Godot require desktop installation, proprietary scripting languages, and complex build pipelines. SpawnForge runs entirely in the browser — you can go from idea to published game without leaving your browser tab.
Where other tools add AI as an afterthought, SpawnForge was built AI-first. The entire engine is controllable through 351 MCP commands, making it the most AI-accessible game engine available. AI is not a feature — it is the primary creation interface.
