AIUsageWatchAIUsageWatch vs CodexBar.
Find your fit.
Both apps put AI usage information in the Mac menu bar. AIUsageWatch concentrates on a compact bar for each configured account. CodexBar covers more providers and a wider set of usage, spending and status features.
Which should you choose?
Choose AIUsageWatch if your main question is how much allowance is left across your configured Claude, Codex, Cursor and Grok accounts, and you want distinct account colours and letters. Choose CodexBar if you need a broader provider catalogue, widgets or richer spending information.
CodexBar is a free, open-source menu bar monitor with a wider provider catalogue, reset countdowns, spend information and widgets where supported. Its range makes it useful when your tools extend beyond AIUsageWatch’s four providers. Official source ↗

A compact account view or more reporting depth?
If you already know which accounts you use and want to see their remaining allowance together, AIUsageWatch’s fixed account identity can be useful. Its colours identify accounts rather than changing to represent usage. It keeps the everyday decision close: which account has room for more work? For reporting beyond those accounts, review CodexBar’s supported features and data sources before choosing.
What an AIUsageWatch reading means
The filled bar is allowance left, and colour identifies an account. Separate Claude and Codex directories can appear together. Open the menu for reset times and reading status. If a fetch fails, the app keeps the last good number and explains how old it is. Grok readings come from the CLI log; Cursor’s included-usage figure is not assumed to be weekly.
Live monitoring uses your existing provider authentication. At a live Codex weekly balance of 100% remaining, the app can send a small request to start the weekly window. It consumes a small amount of allowance; read the starter details before use.
Common questions
Is AIUsageWatch a replacement for every CodexBar feature?
No. AIUsageWatch focuses on remaining allowance for Claude, Codex, Cursor and Grok accounts. It does not provide CodexBar’s broader provider catalogue, widgets or token-cost reporting views. Its public release is still in preparation.
Can AIUsageWatch guarantee that I will not hit a limit?
No. Readings depend on provider data, refresh timing and permissions. Saved readings can be old, and providers can apply other restrictions. The app shows available information and does not increase your allowance.
Can I download AIUsageWatch today?
The public release is in preparation. The website has an illustrative preview and setup information. A verified download link will be added when it is available.
