Codync is an open-source Grok Bot and Muse alternative that runs 40 coding agents as named bots on your Mac

Running Claude Code on one machine and Cursor on another means two separate chats, with no memory of what the other agent was doing, and no way to approve a file edit from a phone when the laptop is closed. Codync, an MIT-licensed desktop and mobile app from a developer who goes by leepokai, puts every coding agent on your computer behind one named bot you can message from any device. The v2.2.3 release went out today, and the project is on its second Product Hunt launch.

The project page positions Codync as the open-source alternative to two paid products: Grok Bot from SpaceXAI, and Muse from Meta. The two paid tools let a user name a coding agent, give it a persistent memory, and talk to it from a phone. Codync offers the same set of features without a subscription and without an account on anybody else's server.

What it runs

Codync supports Claude Code, Codex, Cursor, Gemini, Copilot, OpenCode, Pi and Grok Build, plus about forty other coding agents through the Agent Client Protocol, according to the project page. Each agent is wrapped as a named bot. A user can start a one-to-one thread with any single bot, or open a group chat where several bots take turns on the same task.

Approval cards pause the agent before it writes to a file. The user picks "allow once", "always allow" or "deny" from the phone or desktop. Voice calls let the user speak to a bot, and routines let a bot run on a schedule. The remote channel to the phone runs end-to-end encrypted through a Cloudflare relay, so the project operator never sees the content of a message.

How it is distributed

The macOS build is signed and notarized, and installs through brew install --cask leepokai/codync/codync or a signed .dmg from the GitHub releases page. The Linux build is a native GTK 4 app installed through a shell script. The iPhone app is on the App Store. The source lives at github.com/leepokai/Codync, which currently shows 61 stars, 5 forks and 481 commits. The repository's first release was v1.0.1 in March 2025, and the 2.2 series started on 25 September 2026.

The project claims no benchmark numbers and no user count, and the GitHub repository is small enough that nothing about adoption can be read off its star count. The honest statement is that a mature, native, open-source tool now does what Grok Bot and Muse charge a subscription for, with the trade that a user runs the whole thing on their own machines and signs their own SSH relay.

For a team already paying for one of the hosted agent-chat products, the question Codync forces is whether the convenience is worth the subscription when a free MIT-licensed alternative with the same features now ships natively. For a team that is not paying for one, Codync is the first way to talk to several coding agents from a phone without handing the conversation to a vendor.
