What Hailbar does
Hailbar is a menu bar app for macOS that monitors AI coding agents — Claude Code, OpenAI Codex CLI, Gemini CLI, Cursor's agent, Aider and opencode. It shows every live session and its state (Needs you, Working, Your turn, Error, Finished), notifies you the moment an agent asks for permission or input, jumps to the right terminal tab or editor window, tracks tokens, API-equivalent cost and Claude 5-hour/weekly limits, searches all past sessions, and keeps the Mac awake while agents work. It reads local files only: no account, no cloud, no analytics.

Frequently asked questions
How do I get notified when Claude Code needs my input?
Hailbar sits in the Mac menu bar and sends a notification the moment Claude Code (or Codex CLI, Gemini CLI, Cursor's agent, Aider, opencode) asks for permission or input, then jumps you to that terminal tab.
How can I track Claude Code usage limits and cost on Mac?
Hailbar shows tokens and API-equivalent cost per session, project and day, plus your Claude 5-hour and weekly usage with reset times, read from local files.
Does Hailbar send my code anywhere?
No. It reads local transcript files only and makes no network connections in the App Store edition. No account, analytics or cloud.
