Codync turns the coding agents on your computer — Claude Code, Codex, Cursor, Pi, OpenCode, Grok Build, Gemini, Copilot, Hermes Agent and ~40 more — into persistent *bots* you delegate to from your iPhone, Mac, Windows PC, Linux desktop or any terminal, the way you'd message a colleague. Pick who, say what, put the phone away. You get a notification when a bot finishes or needs your approval.
Why bots? On a phone, "find the right working session, then pick an environment" is too slow. With bots you already know who to hand the intent to: open the chat, type, done.

Why Codync

- Free and open source. No subscription, no paid tier, Apache 2.0 licensed.
- Bring your own subscription. Bots run on the Claude, ChatGPT or other plan your agents are already signed in with, on your own computer. Codync never calls a provider's API with your login.
- Agent-agnostic: bring any coding agent. Claude Code, Codex, Cursor, Gemini, Copilot, OpenCode, Pi, Grok Build and ~40 more — everything in the ACP registry. Installed agents are found automatically, the rest are fetched on first use, and every bot picks its own. Mix them freely: a Claude bot can ask a Codex bot for a review.
- Many bots, one team. Run as many bots as you like side by side, each with its own agent, project folder…
