bb is an agentic orchestrator GUI, not unlike the Codex app, but it works with any provider: Claude Code, Codex, OpenCode, and more. What makes bb different is that it can customize and extend itself. Almost anything in bb can be changed with a single prompt. Ask for a task tracker, and one appears. bb also creates a skill that teaches all of your agents how to use it. Instead of waiting for your agentic workspace to add the feature you need, you can just ask for it.
