What is it?

ChatDev 2.0 (DevAll) is a multi-agent orchestration platform for building customized agent systems without writing code. Users define agents, workflows and tasks through YAML configuration and a visual canvas in the web console, then launch runs and monitor logs and intermediate artifacts, with human-in-the-loop feedback supported.

The project ships with ready-made workflows for data visualization, 3D generation with Blender, game development, deep research and video explanations. A Python SDK lets developers run YAML workflows programmatically, and the backend is built on FastAPI with a Vue 3 frontend.

The original ChatDev 1.0, a virtual software company of role-playing agents, has moved to a separate branch for maintenance.

Key features

  • 01Define multi-agent systems and workflows through YAML configuration without coding.

  • 04Human-in-the-loop feedback during execution.
  • 05Python SDK for running workflows programmatically.
  • 06Docker Compose setup for running backend and frontend together.

Use cases

  • Automating data analysis and generating charts from uploaded CSV files.
  • Running deep research workflows that gather and summarize information on a topic.
  • Building game prototypes or 3D models from natural-language prompts.
  • Integrating agent teams into automation scripts via the Python SDK.

Quick start
