Gatus

The automated status page that you deserve. If your infrastructure went down right now, how long would it take for you to know? Gatus was made to monitor everything, in every possible way. HTTP, GraphQL, DNS, ICMP/PING, TCP, certificate expiration, you name it. While checking the response status may be enough for some use cases, Gatus goes much further and allows you to add conditions on the response time, the response body, and even the IP address. Unlike the competition, Gatus is completely open-source. If there's a feature you want to see, it's as simple as creating an issue on the public repository, or implementing it yourself! Gatus supports alerting on platforms like Slack, PagerDuty, Teams, Twilio, Discord, and many more. If the built-in alerting providers aren't enough for you, you can even create your own! Each endpoint can have one or multiple alerts with different thresholds!
