You can use UptimeRobot to check whether your websites, APIs, servers, and endpoints are online and working. It checks your sites as often as every 30 seconds and sends alerts via email, SMS, Slack, or phone calls when something goes down. You can also monitor SSL certificates, DNS changes, cron jobs, keywords on pages, and port availability. It includes public status pages so you can communicate outages to your users, plus incident management tools for your team.
