Create your avatarThe 4-step workflow: give a coding agent one PNG, fine-tune in the editor.
Try it with zero installThe browser Player: face tracking and lip sync in Chrome or Edge, nothing uploaded.
No illustration? Generate one--random has Codex draw an anime-style girl and rigs her automatically.
Streaming & performing
OBS streaming setupCalibrate, copy one URL, add a Browser Source — transparent background included.

What is Mesh Avatar Studio?
A free, open-source tool (MIT License) that converts one head-and-shoulders illustration into a live 2D avatar. A coding agent such as Claude Code or Codex prepares the rig from your image; you fine-tune it in a local editor with a live preview, then puppet it with webcam face tracking and microphone lip sync.
- Blink, talk and turn its head — driven by mesh deformation, no animation frames needed
- Breathe and sway its hair — continuous idle motion keeps the character alive
- Follow your face and voice — processed locally; camera data never leaves your machine
- Stream to OBS — transparent-background browser source, expression hotkeys, lighting presets

FAQ
- Is Mesh Avatar Studio free?
- Yes — the code is MIT-licensed and free. The bundled sample character has her own usage guidelines.
- What kind of illustration works best?
- A front-facing, head-and-shoulders PNG with a transparent background. No illustration? Use
--randomto generate one. - Can I use it for VTuber streaming in OBS?
- Yes — calibrate the Live page, copy the OBS URL and add it as a Browser Source (e.g. 1080 × 1080).
- Does it work without installing anything?
- Yes — the browser Player runs face tracking and lip sync entirely in Chrome or Edge. Nothing is uploaded.
- How is it different from Live2D?
- It is a free, open-source alternative focused on one workflow: one illustration in, a streaming-ready avatar out, with a coding agent doing the rigging. See the full comparison.
- Is this the official site?
- No — unofficial fan-made tutorials. The official project is on GitHub.
