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.
