A status page tells customers whether your service is down, and the main choice is where it runs. If your own server goes down, a page hosted on it goes down too, so some of the best options here are built to live elsewhere. Upptime runs on GitHub Actions and publishes to GitHub Pages, which costs nothing and survives your outage. Gatus and Kener are lightweight self-hosted services configured in YAML or a small database, good for engineers who like keeping monitors in version control. Uptime Kuma is the most popular friendly dashboard, with a clean UI, notifications and optional public status pages, but it is a monitor first and a customer-facing page second. OpenStatus and OneUptime go further, adding incident updates, subscriber emails and on-call features, with hosted plans next to the open code. The trade-off is where the monitoring probes sit: a probe on the same network as your app cannot see an outage that is outside it, so run at least one probe from a different provider. Also check notification channels and whether customers can subscribe by email, since a page nobody is told about does little. Start with the smallest tool that meets those two checks.
MIT-licensed monitor with a polished dashboard, many notification types and public status pages. Self-host with Docker; subscriber email updates for customers are not its focus.
