Trek runs your coding agents from one inbox.

A native Mac and Windows app where Claude Code, Codex and your other agents work side by side, and whatever needs you comes first.

Free and open source. macOS 13 or later, Windows 11.

Trek on a Mac. The Inbox in the sidebar lists three threads that are waiting, with the reason for each, and one that has finished. The open thread shows an agent's plan with the buttons Keep planning and Approve and start.

Answer one, and it goes back to work.

Start as many threads as you like and leave them to it. When one stops for an approval, a question or a plan, it moves to the top of the Inbox and says why. Answer it there or from your phone. Finished work waits until you have read it.

Your agent can run the app it just built.

On a Mac, Trek hands the agent the iOS Simulator and your iPhone. It builds the app, launches it, reads the screen and taps through its own work, while you watch in the panel beside the thread.

Trek on a Mac. A thread asks the agent to check the Threads screen on the simulator, and its answer describes what the screen shows. Beside it, Trek's Simulator tool shows an iPhone running that app.

The phone is the inbox and the remote.

The agents keep running on your computer. Trek for iPhone shows every thread and what state it is in.

  • Answer approvals, questions and plans.
  • Steer a thread, or start a new one.
  • Use Notes and voice input.

Trek on an iPhone: an agent asks to run a command, with the buttons Deny and Allow.

Free, and yours to read.

Trek is open source under Apache 2.0. It drives each agent's own command-line tool, so your subscriptions work as they do in the terminal.
