Quick answer
Pick by where you work. ccusage and tokscale suit the terminal, CodexBar and OpenUsage suit a Mac menu bar, and UsageAtlas, Token Monitor, and CodeBurn run on Windows, macOS, and Linux. Try UsageAtlas if you want live limits and months of local history in one free app.

How to pick
- You live in the terminal and want reports or JSON for scripts. Use ccusage.
- You are on a Mac and want one small meter for many providers. Use CodexBar.
- You want to cut spend by task or branch. Use CodeBurn.
- You want live limits, alerts, and 90 days of history on any desktop OS. Use UsageAtlas.
Where UsageAtlas falls short
UsageAtlas reads 14 tools. CodexBar, Token Monitor, and CodeBurn read more, so check the provider list first. It has no CLI and cannot cap spending. The Windows installer is not code-signed yet, so SmartScreen asks before the first run.
Questions, answered
What is the best free Claude Code usage tracker?
For terminal reports, ccusage. For a desktop app with live five-hour and weekly limits, alerts, and history, UsageAtlas. Both are free and open source.
Which usage trackers work on Windows?
UsageAtlas, Token Monitor, CodeBurn, and SessionWatcher run on Windows. CodexBar, OpenUsage, and ClaudeBar had no official Windows build as of October 2026.
Do these trackers read my prompts?
Most of them read token counts from local logs. UsageAtlas counts tokens and never sends prompt text anywhere. Check each project's docs for the rest.
