bb

About

bb is an open-source agentic IDE that is itself built and maintained by agents: its repo carries .bb/skills, AGENTS.md, CLAUDE.md, and its own plans directory, and the codebase is developed largely by agents working inside it. Every interface - Electron desktop app, web app, CLI, and HTTP API - is a first-class way to drive the IDE, so automation and human use share the same entry points. Work runs in live steerable threads that can be watched and redirected mid-flight, and threads can hand off to other agents mid-task. A plugin marketplace (community plus bundled and local-path sources) extends the editor, and multi-device access works over Tailscale. The project is MIT-licensed, rapidly evolving, and installed via npx bb-app or desktop releases, appealing to developers experimenting with agent-built tooling.
