Total Spend at a glance
See what Claude, Codex, Cursor and Grok cost today, yesterday or over 30 days, all in one ring.
Know before you run out
Pace markers and flame warnings tell you when you're burning too fast, and exactly when you'll hit the wall.
Pinned to your menu bar
Star up to two metrics per provider. Just look up and know where you stand.
Arranged your way
Turn providers and metrics on or off, drag them into order, and tuck the rest behind a tap.
Every account, every Mac
Track several Claude and Codex accounts side by side, with usage history synced over iCloud.
No login, no leaks
It reads the credentials already on your Mac, and hides your numbers while you share your screen.
One signal. Every screen.
Think of it like a weather station. OpenUsage does all the measuring. Your status line, your editor, your agents? They just read the forecast through a local API or the openusage command. No tokens, no auth, no setup.

Fully built with AI.
A native macOS app built with Swift and SwiftUI. Jump in, fix a bug, or add a provider. Every contribution makes it better for everyone.
Meet the maintainers.
Keeping it sharp, one provider at a time.
AI educator who helps businesses put AI to work: automate the emails, content, and reports nobody wants to do, and build the simple tools their customers need.
Machine learning engineer who also ships macOS menu bar apps and Homebrew tools. Most of my public work is small utilities that fix everyday developer friction.
Software engineer with a long habit of open-source side projects: dotfiles, parsers, small games, and benchmarks when something needs measuring.
Never get cut off
by surprise.
