Web & API Health Checker

Web & API Health Checker keeps an eye on your websites and REST APIs around the clock, so you find out the moment something goes down — not when your users tell you. 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.
