All your AI usage, one glance away.
A tiny, native Windows tray app that tracks your Claude, OpenAI, Gemini, Codex and xAI limits in real time — so you never hit a rate cap by surprise.
If you live in Claude, ChatGPT, Gemini or Grok, you already know the feeling: you're mid-flow and slam into a rate limit with no warning. GPTBar puts every provider's usage in your system tray, color-coded at a glance, and pings you before you run out — not after.
- 🎯 No surprises — a tray icon that turns amber, then red, as you approach your limits.
- 👁️ One pane of glass — Claude, OpenAI, Gemini, Codex and xAI side by side. Stop juggling five dashboards.
- 🔒 Private by design — keys live in the Windows Credential Manager, never in a config file. No accounts, no telemetry, no cloud.
- 🪶 Featherweight & native — built with Rust + Tauri. A few MB, near-zero idle CPU, lives quietly in your tray.
- 🆓 Free & open source — MIT licensed. Audit it, fork it, ship it.
⬇ Download the latest installer — grab the .exe (NSIS) or .msi from the Releases page, run it, done.
Once installed, GPTBar updates itself — new signed releases land in-app with a one-click "Install" banner.
Requires Windows 10 (1803+) or Windows 11. WebView2 ships with the OS.
