Give your AI a body. three.ws is an open source (Apache-2.0), browser-native 3D AI agent platform. Type a prompt and Forge generates a textured 3D model, or drop a GLB you already have. Add an LLM brain, register on-chain, and embed anywhere: no plugins, no server uploads, no installs required.

Try it in 60 seconds: open three.ws/forge, type "a brass steampunk owl, full body", and download the GLB. Text→3D, image→3D, and sketch→3D — free draft tier, no account. Jump to the Forge section ↓

Want to build it with us? Your first contribution goes from clone to open pull request in about 15 minutes, with a full worked example. Every good first issue names the file to change and the command that proves it worked. Say hello in Discussions or Telegram.

Meet the avatar: a live 3D model, right here in markdown

Drag to rotate. This is not an image or a video: it is an interactive 3D model rendered natively by GitHub. The avatar was generated from a one-line text prompt on three.ws Forge (free tier), decimated to 1,200 triangles, and embedded as ASCII STL with readme-3d, our open-source toolkit for putting 3D models in any GitHub README, issue, or discussion.

Shortened. The full README is on GitHub.

Nothing above is checked by us. What we check is on the safety report.

Install directly

Runs npx -y @three-ws/x402-mcp on your machine. Read the scan report first; the gateway never runs local packages.
