Show HN: Relay – A Mac app that carries replies between Claude, Codex and Cursor

Simply put, Relay is just a copy-paster between Claude, Codex and Cursor. It adds a /relay command to those GUIs that just sends the chat history since last over to the other side.I’ve been working on this small Mac app called Kanary that offers essential features. While building it, I found myself stupidly repeating the process of being a messenger between Claude and Codex.Then I thought, why not build a feature that helps my development process? What if Kanary could be a meta-app that bridges between harnesses? That’s when I hit on the idea of a meta harness. A wrapper that works IN the GUI apps that we already use, not a new app.It’s still just a copy-paster, but it has changed how I work tremendously. So far it’s a painkiller for me, not a vitamin. I’d love to hear what you think of this simple tool that does this one simple thing.
