bb

bb is an open-source, local-first IDE for running coding agents, with Claude Code, Codex, Cursor, OpenCode, Grok and others each working in their own threads on your existing provider subscriptions. Much of bb is built as plugins using the same tools users get, including the GitHub integration, agent memory and scheduled jobs, so a single prompt can add a new panel, command and agent skill. Teams that want their own agent workbench can fork the MIT-licensed repo, and any script, cron job or chat bot can start a thread through its CLI.
