Harness by Autonomous

Harness by Autonomous is an open-source command center for coding agents. It lets you run and manage multiple AI coding agents—such as Claude Code, Codex, and Hermes—across every machine from a single interface, with a native desktop app, a terminal client, and iOS/Android apps for answering agents by voice. Communications are end-to-end encrypted, and the platform extends beyond code with 49 harnesses for domains like CAD, circuits, robots, games, and music. It is free on Mac and Linux.
