AgentBell for Mac
Know when your agent needs you

AgentBell is a free Mac menu bar app for people who run Claude Code or Codex in the terminal. When the agent waits for your approval or finishes, you hear a sound and see a big banner, even over a full-screen app.

Key features

Connect in one click. AgentBell rings when the agent needs your approval, your reply, or has finished.
A BANNER YOU CANNOT MISS
A large banner at the top of the screen, even over full-screen apps, with Go to Terminal and Snooze buttons.
JUMP STRAIGHT BACK
Click the banner to land in the right terminal, answer, and let the agent keep going.
REMINDERS AND QUIET TIME
A reminder if you have not answered, and Quiet for 1 hour when you need to focus.
SAFE SETUP
Connect adds one small hook to the agent config and saves a backup first. Remove takes out only what AgentBell added.
