Burndown: AI Code Usage Meter
Session limits & live sessions
Only for Mac
$0.29
Mac
Stop hitting limits mid-task. See when you'll run out at the current pace and which session is waiting for you, right from the menu bar.
Burndown shows your AI coding subscription usage (Claude Pro or Max) as numbers in the macOS menu bar. The menu bar shows the percent of the limit you pick and the time until it resets. Click it for a burndown chart, every limit, and your running Claude Code sessions.
Burndown chart
- Your usage curve for the current 5-hour window, with a dashed line to where you'll hit 100% at this pace.
- Tells you if you'll run out before the reset: "Out by 4:10 PM · 48m early".
Limits
- 5-hour session, weekly (all models) and per-model weekly limits with percent and reset time.
- Pick one limit for the menu bar or let Auto show the highest. Amber badge over 70%, red over 90%.
- A ! appears in the menu bar when a limit you didn't pick passes 90%.
Session monitoring (optional)
- Turn it on in Settings: Burndown adds 7 hooks to ~/.claude/settings.json and keeps a backup of the original.
- Each session shows Working, Needs approval, Question or Done, with alerts when it needs you or finishes.
- Session events stay on this Mac (127.0.0.1); conversations are never stored. Remove it anytime in Settings.
Weekly report
- Active days, days at the limit, daily peaks, sessions and lines changed, today's busiest projects.
