Harness is the open-source command center for coding agents. Claude Code at work, Codex at home, Hermes in the cloud: every agent on every machine, side by side. Use the native desktop app, hn in your terminal, or the iOS and Android app to answer agents by voice. End-to-end encrypted. Then go beyond code with 49 harnesses for CAD, circuits, robots, games and music. Free on Mac and Linux.








Congrats to the Autonomous team on open-sourcing Harness. The coding-agent panes are clear; the CAD, circuits, and robots harnesses with a live viewer are the part I am still mapping. For something like MuJoCo or CircuitJS, what does a blocked "needs human" look like compared to a coding agent asking to push, and can you clear those from the phone the same way?
@genedai Thanks Gene! Under the hood, every domain harness is a regular agent paired with a live viewer. So a blocked MuJoCo or CircuitJS harness looks exactly like a coding agent asking to push: the same question in its pane, the same spot in the "waiting" list, and yes, you clear it from your phone the same way. The difference is what you check before answering: a simulation run or a scope trace in the viewer instead of a diff. Which harness are you most curious to try?
Nice that Harness gives every coding agent and machine one command center, so I can run Claude Code and Cursor side by side without juggling terminals.
@karimbenkeroum Thanks Kareem! Running Claude Code and Cursor side by side is exactly how we use Harness every day. Each one gets its own pane and its own branch, so they never step on each other. Which agents are you running?
