CUStats lives in your menu bar and tracks your Claude and OpenAI Codex usage limits in real time — so you never get rate limited mid-flow.

One-Time Purchase · Costs less than one month of your Claude or Codex subscription

Sound Familiar?

You're deep in a coding session — 45 minutes into debugging a critical issue with Claude or Codex — and suddenly: rate limited. No warning. No countdown. Your entire context, gone.

There's no easy way to see your real-time usage at a glance. How close am I to my limit? When does it reset? How much do I have left this week? You have to stop what you're doing to find out.

You're juggling work and personal accounts across Claude and Codex, switching between tabs, losing track of which one still has capacity.

You shouldn't have to guess how much usage you have left.

Built for developers who rely on Claude and Codex every day

  • Claude Pro & Max users tracking 5-hour and 7-day limits
  • OpenAI Codex users monitoring usage consumption
  • Teams managing multiple Claude and Codex accounts
  • Anyone tired of guessing when their usage resets

Why I Built This

From a real problem to a real solution.

"I was deep in a coding session — 45 minutes into solving a critical bug with Claude and Codex — and suddenly: rate limited. No warning. No countdown. My entire context, gone."

"There was no easy way to check my real-time usage at a glance — across Claude and Codex, across multiple accounts. How close am I to my limit? I couldn't find a single tool that tracked this. So I built one."

"Now I just glance at my menu bar. Green means I'm good. Yellow means slow down. Red means take a break. 19 releases and 207 builds later, CUStats tracks Claude and Codex across macOS and iOS — because no developer should lose their flow to a surprise rate limit."
