Looking for an UptimeRobot alternative that focuses on SSL certificate monitoring?

StableSSL is a focused alternative for teams who want SSL/TLS certificate monitoring without the overhead of a broader monitoring platform.

About UptimeRobot

UptimeRobot is primarily a website and service uptime monitoring tool. SSL certificate expiry checking is one feature among several uptime-focused checks.

When UptimeRobot is the right fit

  • Your main need is HTTP/website uptime monitoring
  • You want a single tool for both uptime and basic SSL checks
  • Your services are all on the public internet

When StableSSL might fit better

  • SSL certificate management is the problem you're actually solving
  • You have certificates on non-HTTPS services (mail servers, LDAP, FTP)
  • Some of your certificates live on internal services behind a firewall
  • You want certificate chain inspection, history, and tagging for organization
