Codexbar

CodexBar is a free, open-source macOS utility that lives in your menu bar and keeps tabs on your AI coding limits. If you use tools like Codex, Claude, Cursor, or any of the 56 supported providers, you know the pain of hitting a rate limit mid-task. CodexBar shows your session, weekly, and monthly usage windows with countdowns to the next reset, so you always know how much runway you have left. It also displays credit balances, monthly spend, and even local cost scans for providers like Codex and Claude.

The app works by authenticating with each provider via OAuth, cookies, API keys, or device flow, depending on what the service supports. Once connected, each provider appears as a status item in your menu bar, showing real-time data like "89% left" and "resets in 4h 12m." You can click into any provider to see a detailed breakdown of usage, spend, and token counts. CodexBar also polls provider status pages and surfaces incident badges when services are degraded or down. It’s a straightforward tool that solves a specific annoyance — no fluff, no dashboards to learn.

This is perfect for developers who rely on multiple AI coding assistants and want to plan their work around limits instead of being surprised by them. It’s also useful for power users on paid plans who want to track monthly spend or monitor token usage across accounts. Because it’s open source, you can inspect the code, add custom providers, or tweak it to fit your workflow. If you’re on macOS 14+ and regularly use AI coding tools, this is a small download that can save you from a lot of frustration.
