Quick answer
ClaudeBar is a free menu bar app for Claude and about 28 other providers, and it needs macOS 15. A Windows port is in progress but had no release as of October 2026. UsageAtlas runs on Windows and Linux today and shows Claude Code's five-hour and weekly limits with reset times.
Claude usage on Windows and Linux
- Five-hour and weekly limits as percentages, with reset times.
- Usage credits left this month, if you turned them on.
- Tokens and estimated cost by day, project, session, and model.
- An alert when a window drops to the level you pick.
Where the two differ
ClaudeBar covers more providers and stays small in the menu bar. UsageAtlas keeps longer history and runs on all three desktop systems. ClaudeBar uses the Apache-2.0 license and UsageAtlas uses MIT, so both are open source.
