ClaudeBar in short, and the free pick when you are not on a Mac

What the open-source menu bar app tracks, its notch and Touch Bar extras, how it compares with CodexBar, and what to use on Windows or Linux.

ClaudeBar is a free, open-source macOS menu bar app that shows how much of your AI coding quota is left, for Claude and a long list of other tools, with a countdown to each reset. It needs macOS 15 or later, so if you code on Windows or Linux, or you want a longer history next to the meter, UsageAtlas is the free pick we would install instead.

What ClaudeBar shows

ClaudeBar comes from tddworks and carries the tagline "Every AI coding quota in your menu bar." Despite the name, it is not only for Claude. Its provider table includes Codex, Gemini, Copilot, Cursor, Antigravity, Kimi, Warp and many more, and you can add your own source with a script.

For Claude, it tracks the five-hour session and weekly limits, the per-model limits and Extra Usage. You can put up to three providers in the menu bar as a percentage with a reset countdown, or show a simple status icon. A forecast line under each countdown says whether the window will last until it resets at your current pace.

Install takes one line:

brew install --cask claudebar

There is also a signed and notarized DMG on the releases page. The ClaudeBar site says the app is free forever and kept going by sponsors, and the code is under the Apache 2.0 license.

The fun extras

ClaudeBar has more personality than most quota meters:

  • Notch view. Quota and live Claude Code sessions in the MacBook notch.
  • Touch Bar gauges for the MacBook Pros that still have one.
  • Themes, including a terminal-style one and a Christmas theme that switches itself on for the holidays.
  • A leaderboard where you can share daily token totals.
  • Webhooks that post quota alerts to Slack or a URL you own.

ClaudeBar and CodexBar, in one paragraph

Both are open-source menu bar meters for AI coding limits on the Mac. CodexBar supports macOS 14 and later, uses the MIT license, lists even more providers, and also ships for Linux. ClaudeBar needs macOS 15, leans into Mac hardware features like the notch and Touch Bar, and adds forecasts and webhooks. Neither offers an official Windows download as of November 2026; ClaudeBar's latest release ships a DMG and a zip for macOS.

Where UsageAtlas comes in

A menu bar meter is great for a glance. It is less helpful when you switch to a Windows laptop, or when you want to see which project ate your weekly Claude window.

UsageAtlas covers both cases. It runs on Windows, macOS and Linux. For Claude Code it shows the five-hour and weekly limits as percentages with reset times, usage credits left if you turned them on, and tokens and estimated cost by day, project, session and model. It can warn you when a window drops to a level you choose. It reuses the Claude Code sign-in already on your computer, needs no account for local tracking, and does not read prompts or responses. It is free and MIT licensed.

Which one to install

  • Mac only, and you love the notch: ClaudeBar.
  • Mac only, with a very long provider list: CodexBar.
  • Windows or Linux, or a mix of machines: UsageAtlas.
  • You want history, not just a meter: UsageAtlas, on any of the three systems.

If you are not sure, start with UsageAtlas, since it is the only one of the three with builds for Windows, macOS and Linux. You can still add a menu bar meter beside it on a Mac; each one reads your existing sign-ins on its own.
