SessionWatcher vs CodexBar and Other CodexBar Alternatives
CodexBar is free, open source and tracks more providers than SessionWatcher: its README lists 110, against our 22. On a Mac or Linux, if free matters most, use it. SessionWatcher is paid, and the differences are specific: a native Windows app, one licence for Mac and Windows, an iPhone and Apple Watch companion in beta, applying Codex banked resets from the menu bar, and support from the person who builds it.

What CodexBar is
CodexBar, by Peter Steinberger, is an MIT-licensed menu bar app for macOS 14 or later with about 23,000 GitHub stars. Per its README it also ships a Linux desktop app and a command-line tool, covers 110 providers (Codex, Claude, Cursor, Gemini, Copilot, OpenRouter and many more), and shows session, weekly and monthly windows with reset countdowns, credits and spend, provider status, macOS widgets and optional notifications. It installs with Homebrew. It costs nothing.
It has no official Windows build. Its README points Windows users to community ports; we compare them in CodexBar for Windows.
Where SessionWatcher is different
- A native Windows app. SessionWatcher for Windows puts each tool's usage inside the Windows 11 taskbar (a small window beside it on Windows 10), on x64 and ARM64.
- One licence for Mac and Windows. The same key works on both; Pro covers up to 5 devices in any mix.
- iPhone and Apple Watch companion, in TestFlight beta: the limits your Mac tracks, in widgets, the Dynamic Island and on the Watch.
- Codex banked resets you can apply. Both apps list your banked resets and their expiry. CodexBar's docs say it does not redeem them; SessionWatcher on the Mac applies one after you confirm.
- Several Claude and Codex accounts side by side on Pro, each with its own limits and reset times.
- A person to email. Support comes from the developer, usually the same day, and every purchase has a 14-day refund window.
What it does not have: CodexBar's provider count, a Linux build, a command-line tool, or a free tier beyond the 7-day trial.

Which one should you pick?

- Windows in the taskbar, or a Mac and a PC on one licence, or the iPhone companion, or someone to email when it breaks: SessionWatcher.

CodexBar is free. SessionWatcher is a one-time purchase, with an optional yearly plan for Pro:
- Single tool (e.g. Codex): $8.99 one-time.
- Bundle (Claude Code, Codex and Cursor): $19.99 one-time.

The verdict
CodexBar is a very good free app, and on a Mac it covers more than we do. We would rather you pick it than buy something you do not need.
SessionWatcher earns its price in specific cases: you work on Windows, you want one licence across a Mac and a PC, you want your limits on your iPhone or Watch, or you want a paid product with a person behind it. If none of those apply, CodexBar is the better choice.
