Claude Meter

Claude Meter

claude-meter is a local research proxy for understanding how Claude Code usage maps to Anthropic's hidden quota system.

Live Dashboard

The core problem is simple:

- Claude Max / Pro users can see rough usage state, but not the real hidden budget
- Anthropic appears to enforce multiple windows such as 5h and 7d
- Claude Code traffic includes useful usage and rate-limit signals, but they are not surfaced in a way that is easy to study over time

claude-meter sits between Claude Code and Anthropic, captures those signals locally, normalizes them, and helps estimate rough budget bands from real traffic.

Status

This project is currently an alpha research tool, not a polished end-user product.

What that means:

- it is already useful for reverse-engineering and observing hidden quota behavior
- it is not yet an exact “Claude Max limit meter”
- current estimators produce rough ranges, not precise truth

The right way to think about the project today is:

- working local proxy
- working local data capture
- working local normalization
- early-stage estimator

What We Are Trying To Do

The immediate goal is to answer questions like:

- what 5h and 7d quota windows does Claude Code actually see?
- how do different models affect those windows?
- do cache reads behave more like cheap API cost than raw token count?
- can we estimate a rough 5h budget band with enough confidence to track changes over time?

The longer-term goal is bigger:

- help users understand their own hidden Claude usage limits
- detect changes in Anthropic behavior over time
- eventually compare behavior across plans, models, and accounts

What Already Works

Proxy

- transparent pass-through proxy for api.anthropic.com
- asynchronous logging so proxying stays ahead of disk writes
- all…
