coucou

Coucou puts a little character in your MacBook's notch (or at the top of the screen on Windows and Linux) that watches your AI coding agents: which files Claude Code, Cursor, Codex or Gemini CLI are reading and editing, the diffs, and when they finish. You can answer permission prompts from the notch, from your iPhone's Lock Screen, or (paired with the Windows or Linux app) from an Android phone. The code is MIT and there's no paid tier.

On a Mac, download the release, drag it to Applications, and click Install hooks; it backs up your Claude Code settings and shows the diff before writing anything. The Mac build is signed and notarized. The Windows installer isn't code-signed yet, so expect an "unknown publisher" SmartScreen warning the first time. Some agent integrations (Gemini CLI, OpenCode, Amp) are Mac-only. The iPhone app is a TestFlight beta, and the Android app has no signed release yet, so you build it from source.

Solo devs running long agent sessions who want to step away from the keyboard get the most out of it. There's nothing for teams to buy or manage. If you only want a general notch utility, boring.notch (TheBoredTeam/boring.notch) is the established open source pick.

The catch: approving agent actions from your phone is a real security surface, even behind Face ID or a fingerprint. It's mostly one developer shipping close to a release a day since launching in late September 2026, and the scope keeps widening (mail, crypto prices and Spotify pills are recent additions). And forks can't reuse the name, character, icon or sounds, because those assets aren't MIT.
