Why it matters

For people running AI coding agents on more than one computer who lose track of which agent is working, stuck or waiting. It shows them all in one place and keeps them running when you close the app.

Highlights

Shows agents such as Claude Code, Codex, Cursor, OpenCode, Devin, Amp and Copilot side by side, each in its own tmux pane and its own git worktree so they don't clash.
Links your machines with a password, with no SSH keys or port forwarding; traffic is end-to-end encrypted and a relay forwards only ciphertext.
Agents keep working when you close the app, and you can answer agents that are waiting or send a task without choosing which machine runs it.
A Harness Store adds harnesses for other crafts, such as Blender, CircuitJS, MuJoCo, Godot and Strudel, with live viewers.
Desktop, terminal and mobile apps are available; the Harness Device ($149) and Harness Pro ($299) are desk displays that show agent progress and take voice tasks.unverified

Taken from the project's own README, docs or launch page. Claims about speed or accuracy are the maker's unless stated otherwise.

Try it if: You have agents running on a laptop, a desktop and a server and keep switching windows to see which one needs you.

Worth knowing: Sign-in to a Harness account is required (harness login). Connecting machines gives the app remote terminal access to them. The Linux desktop app is listed as in progress on one page but downloadable on another.
