How to choose
Start with the job you need done: alerts when a site or service goes down, resource monitoring for your servers, or a public status page. If you mainly want uptime checks with alerts, uptime-kuma covers HTTP, TCP, DNS and more. If you want CPU, memory and Docker stats per server, beszel is aimed at that. If you don't want to run a server at all, upptime runs entirely on GitHub Actions and Pages.
- uptime-kumaBest for people replacing UptimeRobot or Pingdom who want HTTP, TCP, DNS, ping and Docker checks with alerts and status pages.
- beszelBest for anyone who wants a lightweight dashboard for server resources, Docker container stats and history, with alerts.
- upptimeBest for people who don't want to run a server and would rather get monitoring and a status page from GitHub Actions, Issues and Pages.
