Harness
An open-source command center for coding agents on your machines.
Harness is a command center for coding agents, from Autonomous. The docs say it runs agents such as Claude Code and Codex in terminal sessions on your own computers, and shows them in desktop, web, and phone apps. A local start does not need an account. The same page says the source is MIT licensed, and that an agent may start other harnesses only after a person turns that setting on. It is off by default.
The product page shows “Harness Pro” at $299, next to copy about progress on a desk. The device page lists a Harness Device at $149 and names Claude Code, Codex, OpenCode, and Cursor among the agents a device can show. Those dollar amounts are hardware. This listing does not record them as a monthly software price.
Harness does not replace Claude Code, OpenCode, or Cursor. It is a way to watch and dispatch agents that still have their own bills.
Pros
- The docs say the app starts locally with no account
- The same docs call the source MIT licensed
- It is a view onto agents you already run, not a new model plan
Cons
- The install notes cover macOS and Linux, not a Windows package
- Letting an agent start other agents is off until a person turns it on
- The $299 on the product page is easy to misread as software
