Harness Manager is the App Store and control center for AI coding harnesses on Mac. Discover, install and update tools like Claude Code, Codex, OpenCode, Pi and more. Automatically detect what’s already installed, manage MCP servers and AI skills, check versions and paths, and diagnose broken installations or configuration issues. Your entire AI coding stack, finally in one place.

Hey Product Hunt I built Harness Manager because I kept forgetting which AI coding tools I had installed on my Mac and where everything was. I use Claude Code, Codex, OpenCode, Pi, MCP servers, skills, and a bunch of other tools. After a while it gets hard to keep track of what is installed, what needs an update, and what is broken. Harness Manager puts all of that in one place. It finds what is already installed, shows versions and paths, helps spot issues, and makes it easy to discover and install other AI coding harnesses. It also keeps up with the ecosystem for you. New harnesses are added as they come out, and there is a news section to keep up with new releases and what is happening across AI coding tools. This is my second Mac app after Port Radar. I built Harness Manager because I wanted one place to keep up with the AI coding tools I already use and discover what is coming next.
