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.
The part I'd pay for here is the diagnosis, not the install. Every one of these tools writes config somewhere different, and most of my breakage is two of them fighting over the same MCP server entry or a stale path after a node upgrade. Discovery I don't need, I already know what I want running. If it can tell me which config file is actually being read at the moment something breaks, that's the whole product.
