Symphony

What is Symphony?

Symphony puts every AI coding agent on your team on one live board. Hooks stream each file edit from Claude Code, Codex, and opencode into Supabase, giving you per-person cards, collision flags before edits become merge conflicts, a token leaderboard, and a 3D map of the repo. Open source (MIT). Self-hosts in minutes with a free Supabase project, locally or on Modal.
