I built a macOS app to manage all my AI coding tool configs in one place

If you use multiple AI coding tools — Claude Code, Cursor, Codex — you probably know the pain of hunting down rule files scattered across different directories, trying to remember where your hooks are, or keeping CLAUDE.md and AGENTS.md in sync.

I built Relay to fix that for myself.

It's a simple macOS app that gives you a unified 3-panel view of everything your AI tools know: rule files, settings, hooks, skills, agents, contexts — all in one place, auto-detected on launch.

What you can do with it:

  • Edit global and per-project rule files with a built-in editor
  • Save rule templates as presets and apply them across tools instantly
  • Register project folders and see all local rule files at a glance
  • Browse config files (settings, hooks) without digging through ~/.claude or ~/.cursor

It's free, open source, and requires macOS 15+.

I'd love to hear what you think — whether it solves a problem you've had, what's missing, or what you'd do differently. Any feedback is welcome!
