Add any web page or API endpoint and the app checks it on a schedule in the background, records the result, and alerts you the instant it fails. When the service recovers, you get a notification too.

WHAT YOU CAN MONITOR
• Websites — just paste a URL
• REST APIs — GET, HEAD or POST health checks
• Custom "healthy" rules — expected HTTP status range, a required text snippet in the response body, and an optional API key header

AT A GLANCE
• Clean dashboard with a "needs attention" summary
• Color status-history bar for every target (Uptime-Kuma style)
• Per-target detail screen with uptime %, average response time, response-time chart and a recent-checks timeline

STAYS ON TOP OF THINGS
• Background monitoring with intervals from 15 minutes to 24 hours
• Instant notification when a target goes down — and again when it recovers
• Quick Settings tile and app shortcuts to run a check on demand
• "Check on Wi-Fi only" option to save mobile data
• Battery-optimization guidance for reliable background checks

BUILT TO BE PLEASANT
• Modern Material 3 interface
• Light, dark and system themes
• Fast, lightweight and privacy-friendly — your endpoints stay on your device

Whether you run a side project, a startup, or just want to know your favorite site is up, Web & API Health Checker gives you peace of mind with a glance. ## Rankings - #2,376,513 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_ADSERVICES_AD_ID` - `android.permission.ACCESS_ADSERVICES_ATTRIBUTION` - `android.permission.ACCESS_ADSERVICES_TOPICS` - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.FOREGROUND_SERVICE` - `android.permission.INTERNET` - `android.permission.POST_NOTIFICATIONS` - `android.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS` - `android.permission.WAKE_LOCK` - `com.android.vending.BILLING` - `com.android.vending.CHECK_LICENSE` - `com.google.android.gms.permission.AD_ID` - `com.siamakerlab.webchecker.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` ## Similar extensions and apps - [API Monitor](https://chrome-stats.com/d/com.apimonitor) — 107 users - [CheckUpTime - Monitor Downtime](https://chrome-stats.com/d/com.checkuptime.app) — 25 users - [Uptime Monitor – URL Alerts](https://chrome-stats.com/d/com.obtech.downlinknotifier) — 90 users - [linkdown](https://chrome-stats.com/d/com.naftech.linkdown) — 366 users - [UpWatch](https://chrome-stats.com/d/me.kandz.upwatch) — 1 users - [Website Uptime Checker](https://chrome-stats.com/d/com.aigenwebupdownchecker) — 279 users - [isthisthing.online: Uptime](https://chrome-stats.com/d/online.isthisthing.mobile) - [Steady - Uptime Monitor](https://chrome-stats.com/d/com.soumyazyx.steady) — 1 users - [Uptime Monitor - Watchlog](https://chrome-stats.com/d/io.watchlog.uptime) — 43 users - [Uptime Squirrel](https://chrome-stats.com/d/com.uptimesquirrel.android) — 64 users - [UptimeRobot: Monitor anything!](https://chrome-stats.com/d/com.uptimerobot) — 408,144 users, 3.36 / 5 - [Web API Uptime Monitor](https://chrome-stats.com/d/com.uptime.moose.monitor) — 93 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.siamakerlab.webchecker)
