Know when you're about to hit your Claude limit
Claude doesn't warn you before it stops. It just stops. CapMeter puts a live usage ring in your menu bar and turns your burn rate into a countdown: "limit in ~1h 18m." You wrap up before the wall, not after. → Alerts to macOS, Slack, Discord or any webhook → Session, weekly and per-model limits, counting down → Floating widget with your $/hr credit burn → 90-day history, CSV export → No API key, no account, no server, no analytics 14 days free, then $14.99 once.

Hey Product Hunt 👋
I built CapMeter because Claude kept stopping on me mid-task. Not slowly.
Just done, no warning. I'd lose the thread of what I was doing and have to
wait it out.
For a while my fix was checking the usage page before every long prompt,
which is a strange way to live.
There were already free menu bar counters showing a percentage. That told me
where I was, but not the thing I actually needed: whether I'd make it to the
end of what I was working on.
So the core of CapMeter is the prediction. It measures how fast you're
burning through your session and turns it into a time: "limit in ~1h 18m."
That one line changed how I work. I either wrap up or switch to a lighter
model, before the wall instead of after it.
Three other things I ended up needing myself:
→ Alerts that reach me where I already am. The menu bar is fine until I'm
looking at another screen, so thresholds can go to Slack or Discord too.
Quiet hours, because I don't want a 3am ping.
→ A floating widget that stays above every window and Space. If you're on
extra usage credits, it also shows your spend rate in $/hr, which is
sobering.
→ History. Daily peaks over 7 / 14 / 30 / 90 days, and this week vs last.
It turns out my usage is much spikier than I assumed.
On privacy: it reads your own logged-in claude.ai session, on your machine.
No API key, no account with me, no server of mine, no analytics. Your token
is encrypted in the macOS Keychain. It never touches your conversations.
It's free for 14 days with everything unlocked, then $14.99 once. No
subscription. macOS 12+, Apple Silicon.
Two things I'd genuinely like input on:
1. What would you want the prediction to do when your usage is erratic:
stay quiet or show a range?
2. Right now, alerts only fire on percentage. If you use extra usage credits,
would a dollar threshold be useful too, like "tell me when I've spent $20
this week"? Extra usage spend is going into the history view next, either
way.
Happy to answer anything.
