Features and specs

What each product offers, as listed by its team.

AppChecks 6 features
HTTP Observatory 0 features
  • HTTP Monitoring
    Ensure the web server is functioning properly with simple and straightforward HTTP monitoring. Check status codes, response times, and full availability.

    Be the first to know about any SSL certificate issues. Notifications are sent 30, 10 and 1 day before certificate expiration, so you'll have enough time to renew it.

    Monitor any port on your server — SSH, FTP, SMTP, databases and more. Make sure critical services behind specific ports are reachable.
  • Ping Monitoring
    Simple and reliable ICMP monitoring. Make sure your server or any device in the network is available and responding.
  • Keyword Monitoring
    Keyword-based monitoring checks presence or absence of a specific word or phrase on a webpage to detect content regressions and defacements.
  • Domain Monitoring
    Never lose your domain again. Monitor domain expiration date.
