About bb

bb is a free, open-source, local-first IDE that runs Claude Code, Codex, Cursor, and other AI agents in one interface. Choose an agent by task, or let one agent generate and manage another in a separate thread. Nearly every part can be changed with one sentence: ask for a task tracker and a sidebar panel plus a teaching skill appear with it; GitHub integration, agent memory, scheduled tasks, and remote access are implemented as plugins. Its CLI is open to external programs, so shell scripts, cron jobs, and chat bots can start work threads. bb uses the MIT license and can be forked and deployed across an organization; agents run on your existing provider subscription and are billed by the provider.

Best for

Developers who use multiple AI coding agents
Engineering teams that want to customize their environment around their own workflows
Users who need scripts, scheduled tasks, or chat bots to start agent work automatically
Open-source users who prefer local-first software they can fork and customize

FAQ

bb is free, open source, and local-first; the official site says it installs in one minute. Each agent runs on your existing provider subscription and is billed by that provider, not bb.
The official page lists Claude Code, Codex, Cursor, Pi, OpenCode, Grok, omp, and Hermes. You can assign a task to the right one, and one agent can generate and manage another, each in a separate thread.
