Coincide

Coincide is a free, open-source native Mac app for the coding agents you already use: Claude Code, Codex, Cursor, Grok Build, OpenCode and Antigravity. Run them at the same time in one window, switch agents mid-thread and the next one picks up where the last left off, and keep them working after you quit. Approve commands right in the thread, and give Bots a personality and a daily routine. Your own accounts and keys; nothing is resold.
