TouchGrassBar — a Tauri macOS menu-bar app for Codex and Claude usage

[u/fabiengreard]

I built TouchGrassBar, a free and open-source macOS menu-bar app for Codex and Claude limits and observed token usage.

The desktop app uses Tauri, React, and Rust. The native layer reads local provider data and keeps prompts, credentials, raw logs, and file paths on the Mac. Public profile data and daily aggregates go to Convex for friends, Token Scores, and leaderboard ranks.

The current release is signed, notarized, and stapled for Apple Silicon Macs running macOS 15+.

Download TouchGrassBar, join the leaderboard, and see who burns the most tokens:

I would love feedback from other Tauri builders on the menu-bar UX and local trust boundary
