Where CodexBar is better
- It's free and MIT-licensed, with a large, active community (21,998 stars and a release on 2026-09-27).
- Far more providers, and a documented way to add one.
- Credit balances and provider incident badges, which Usage HUD doesn't show.
- Homebrew install and a Linux desktop build.
Where Usage HUD is different
- Every number carries a confidence label and a one-line reason, and the bundled
codex-usage-doctorexplains when a reading can't be trusted. - The Claude number comes from the same endpoint
/usagereads, and the app never refreshes your login token. - Ollama counts come from your own local server logs, with no account, for people who mix paid plans and local models.
- A read-only MCP server and command line are built in, so your agents can ask which plan has room before they start. Agent docs.
Which one should you use?
CodexBar covers more tools; start there if coverage is what you want. Usage HUD is the calm verdict: one line that says which plan has room, when this one runs out, and how much to trust each number. Both are free, so you can run them side by side.
Questions
Is CodexBar free?

Should I use Usage HUD or CodexBar?

What Usage HUD is
A Mac menu-bar app that shows how much of each Claude, Codex, Gemini, Grok and Ollama window you've used, when it resets, and a label on every number: official, measured, estimated or unknown, with a one-line reason. The Claude number comes from the same endpoint /usage reads. The app never refreshes or changes your login token. Codex numbers come from the rate_limits events in your local session logs.
Which number is right
Each bar says where it came from and how old it is, so a stale or estimated number doesn't pass as official.
Pace, not just percent
It compares how much you've used with how much of the window has passed.
Stays on your Mac
No Usage HUD account and no analytics in the app. A public README badge is opt-in.
