CodexBar is a strong alternative when desktop breadth matters
CodexBar’s current site presents a free, open-source macOS menu-bar app with provider windows, reset countdowns, charts, spend and cost scans, provider menus, and status polling. Its public repository explains its local-session and privacy approach in more detail.
That is the right shape if your day moves through Codex, Claude Code, Cursor, OpenCode, Gemini, Copilot, or other developer tools and you want one desktop meter. A browser widget is a better fit when the relevant usage signal lives inside web apps and you want it beside browser work. Neither surface is a substitute for the provider’s own account page.
Choose by workflow
- Browser work: prefer a browser surface that keeps provider windows and reset times visible.
- Terminal and desktop work: prefer a menu-bar or CLI tool that can read local sessions, costs, and status.
- Both: compare privacy and data-source boundaries before installing both.
