Universal API Usage Tracker for Windows — Monitor rate limits across all your AI providers.
Inspired by CodexBar by @steipete — the macOS-only original. TokenBar brings the same functionality to Windows users.
If you're vibe-coding with Claude Code, Cursor, or other AI tools, you need to know:
- How much of your 5-hour session limit is left?
- How much of your weekly limit is remaining?
- When does each window reset?
CodexBar solves this beautifully on macOS. TokenBar brings it to Windows.
