  • HTTP Monitoring
    Ensure the web server is functioning properly with simple and straightforward HTTP monitoring. Check status codes, response times, and full availability.
  • SSL Monitoring
    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.
  • Port Monitoring
    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.

Overall verdict

  • AppChecks appears to be a niche monitoring/testing tool, but there is limited public information, reviews, or track record available to fully verify its reliability, feature depth, or company stability, so it should be evaluated cautiously with a trial before committing.

  • May offer competitive or affordable pricing compared to larger established platforms
