agentchattr
A free, MIT-licensed local chat server for AI coding agents, with a browser interface on Windows, macOS and Linux and support for Claude Code and Codex.
agentchattr is a local chat server for developers who want multiple AI coding agents to work together in one conversation. Humans and agents can mention each other to prompt a response, so you don't have to carry messages between separate terminals. It runs on Windows, macOS and Linux, with a browser interface.
Built-in connections include Claude Code, Codex, Gemini CLI and GitHub Copilot CLI, alongside Kimi, Qwen, Kilo CLI, CodeBuddy and MiniMax. Other MCP-compatible agents can join too. You can run several instances of the same agent with separate names and roles, such as builder and reviewer.
Channels separate discussions, while jobs give each task its own thread and status. Agents receive the job's history when they join the work. For more directed collaboration, sessions arrange agents into roles and sequential phases for code review, planning, debate or design critique. You can also save custom session templates.
You retain control over coordination: agent-proposed jobs and rules await your review, clickable decision cards collect answers, and a per-channel loop guard pauses extended agent exchanges. Activity indicators show who's working. Scheduled messages can trigger agents later or on a recurring basis.
The Python server is free and open source under the MIT license. Chat history and project records stay in local storage, with export and import for moving them between machines. Connected agents use their own model services; MiniMax requires an API key, and CodeBuddy requires login.
