What it does

Everything you need to track your Claude limits.

Live Usage Tracking

Displays your current message count and how close you are to your session and weekly limits without opening Claude.

100% Local

All calculations happen on your machine. Czally reads your local browser state — nothing is transmitted externally.

Open Source

Fully transparent. Audit every line. No obfuscation, no telemetry, no surprises. MIT licensed on GitHub.

Zero Config

Install and it works. No API keys, no sign-up, no additional hardware required. Works inside Zen Browser and Firefox.

Privacy

No servers. No data. No trust required.

Czally is built on the assumption that you should not have to trust a third party with your usage data just to track a message counter.

Reads local Claude session state only — never your conversation content
Zero external requests. No analytics, no crash reporting, no beacons
No account, no login, no email required to install or use
Full source available for audit on GitHub at any time
