Your AI limits,
always in sight.

Mimir sits in your macOS menu bar and shows Claude sessions, Codex credits, and Antigravity quotas in real time. No browser tabs, no context switching.

Free & open source

Mimir menu bar popover showing Antigravity (Gemini Flash, Gemini Pro, Claude), Claude (5h Session, Weekly, Sonnet), and Codex (5h Session, Weekly) usage limits with green progress bars and reset countdowns

Three services.
Complete visibility.

Each tracked by reading local config files and macOS Keychain. Nothing is sent anywhere.

✓ LIVE

Local reads only.
No accounts.

Mimir watches the same config directories and Keychain entries that the AI tools themselves write to. It never makes network requests on your behalf.

  • Install and grant file access

    One-time permission to read ~/.claude, ~/.codex, and the Antigravity runtime directory.

  • Mimir reads the local state files

    Usage logs and session state are parsed directly. No API calls, no intermediary server.

  • Limits appear in the menu bar

    Click the icon to see all services, current usage, and exactly when each quota resets.
