Codenotch tracks your AI coding limits right from a screen-edge notch

A neat macOS app keeps you from blowing past your API limits by pinning live usage trackers for Claude Code, Cursor, and Codex directly to your screen edge.

Developer vinzdg released Codenotch, a lightweight macOS utility that attaches a small notch to any side of your display. It reads local sessions already saved on your Mac—like keychain tokens or SQLite databases—to display live usage rings and limit reset windows for Claude Code, Cursor, Codex, and Antigravity. The open-source project picked up 691 stars this week.

Why it matters: AI assistants rarely make their session limits obvious until you hit a wall mid-refactor. Codenotch surfaces those hidden usage metrics without sending credentials off your machine or making you log into extra accounts. It also shows whether a background AI session is actively working or blocked waiting on your input.

Here's the gist on how it stays accurate: Codenotch borrows existing local endpoints instead of guessing. Because vendors change internal endpoints without warning, the app degrades to a visible status like stale or error rather than showing an invented percentage.

It turns out the easiest way to avoid surprise rate limits is keeping an eye right on the edge of your screen.
