Clack Relay for Mac

The other half of Clack. It sits in your menu bar, finds the Claude Code sessions you already have open, and lets your phone talk to them. Free — the app on your phone is the paid part.

Open it once

Drag it to Applications and launch it. It starts the relay itself and keeps running after a restart — there is no terminal step and nothing to configure.

It finds your sessions

Every Claude Code session open on the Mac appears in the menu, and on your phone, by name. You do not tell it where they are.

Nothing leaves your Mac

Your phone talks to this relay directly over your own Tailscale network. Conversations and file contents never pass through us.

Requirements

What you need first

Claude Code on your Mac

Clack attaches to sessions you have already started. If Claude Code is not running, there is nothing for it to join.

Tailscale on both devices

So your phone can reach your Mac from anywhere, privately. Free for personal use.
