CopilotKit open-sources OpenBot, giving each agent its own container, browser and logins behind a single policy gateway

OpenBot reached 3,364 stars and 412 forks since its 2026-08-17 creation, MIT-licensed and pushed 2026-08-28. Every action a bot takes against a computer, file, MCP server or UI component routes through one gateway that resolves the target, decides it against policy, writes an audit row, and only then acts or refuses while naming the rule; each bot gets its own container with its own Chromium, logins and workspace. Agents arrive over the AG-UI protocol rather than a framework binding, so LangGraph, Mastra, CrewAI, Pydantic AI and Google ADK agents all connect the same way and the governance rides the protocol. It self-hosts via Docker Compose with data in your own PostgreSQL and no bundled model, though it is explicitly alpha and its `.env.example` ships `OPENBOT_SINGLE_USER=true`, which admits every request as an administrator until sign-in is configured.
