Keet is your personal API endpoint monitor — a native iOS app that lets you track the health of any HTTP endpoint right from your iPhone.
 
MONITOR EVERYTHING
Configure unlimited endpoints with custom headers, bearer token auth, body validation, expected status codes, and request timeouts. Organize them into color-coded groups like Production, Staging, or Dev.
 
KNOW INSTANTLY WHEN THINGS BREAK
Get push notifications the moment an endpoint goes down — and when it recovers. Keet runs background checks every 5, 15, or 30 minutes, even when the app is closed.
 
LIVE ACTIVITIES
See failing endpoints right on your Dynamic Island and Lock Screen. No need to open the app — glance and know.
 
BEAUTIFUL CHARTS
Interactive response time charts with drag-to-inspect and pinch-to-zoom. Track uptime percentages across 24 hours, 7 days, or 30 days.
 
DEVELOPER-FIRST DESIGN
Dark mode by default. 15 accent colors. Monospaced data labels. High information density. No clutter, no gamification — pure utility.
 
PRIVACY BY DESIGN
All data stays on your device. No cloud sync, no accounts, no tracking. Bearer tokens stored in Keychain, never in plain storage.
 
9 LANGUAGES
English, Spanish, French, German, Italian, Portuguese, Chinese, Japanese, Korean — switchable in-app without restarting.
 
100% FREE
Every feature is unlocked. No ads, no subscriptions, no paywalls. If you find Keet useful, you can leave an optional tip to support development.
 
Perfect for indie developers, freelancers, small teams, and anyone who needs peace of mind about their APIs — without opening  a laptop.
