IDE Now Codes Its Own Features, Developers Left to Just Watch
bb is an open-source, MIT-licensed agentic IDE that can extend itself by building features on demand. It works with popular coding agents like Codex, Claude Code, and Cursor using your own subscriptions. Users have used it to build task managers, code review systems, markdown editors, and even a digital audio workstation directly inside the IDE. The project emphasizes malleability, allowing developers to adapt the tool to their specific workflows rather than settling for one-size-fits-all software.
