UptimeRobot
UptimeRobot monitors your website 24/7 for availability and alerts you in case of downtime. 50 monitors are free.
UptimeRobot is a monitoring service that pings your website, shop, or API at short intervals and immediately alerts you if something is unreachable. Over 800,000 users rely on it, and the first monitor can be set up in five minutes.
The classic scenario: Your shop is down on Sunday night, and you find out from the tool instead of from the first angry customer on Monday morning. Additionally, it provides warnings about expiring SSL certificates and status pages. Its strength is the free plan with 50 monitors checked every five minutes.
Datadog or Pingdom analyze deeper into the code but cost many times more. The honest limitation: UptimeRobot tells you that something is down, but not necessarily why. For root cause analysis, you need access to logs or a true observability tool.
Suitable for practically any company with its own website; at a price of zero, there are few excuses. Those operating complex infrastructure can supplement it with Datadog or similar tools.
