why teams pick concord
Amoeba bundles coordination into a new IDE. Concord gives you stronger coordination without asking anyone to switch editors.
- 01
Keep your editor
Cursor, a terminal, or both. Concord coordinates agents across all of them.
Mix Cursor and Claude Code - 02
Open source, no account
MIT-licensed and local-first. Your team can read every line it runs.
How it works - 03
Enforced, not just warned
concord check turns a claim into a hook or CI gate, so a claimed file can't be edited by accident.
Block claimed edits
