Uptime Kuma is a self-hosted monitoring application designed to help administrators keep track of the availability of websites, applications and network services.
It combines a responsive Vue-based interface with an extensive choice of monitoring methods. Administrators can configure checks, investigate failures, examine historical availability and arrange to receive notifications when something stops responding.
The software is particularly useful for smaller organisations, home laboratories and self-hosted infrastructure, although its range of features also makes it suitable for more demanding monitoring requirements.
Rather than requiring a separate status page product, Uptime Kuma includes tools for publishing service availability information to users and customers.
This is free and open source software.
Key Features

- Provides SSL certificate information to help identify approaching certificate expiry.
