Open Source Uptime Monitoring Software
Uptime Monitoring tools track the availability and response times of websites, APIs, and server endpoints. These tools send alerts through notification channels when a service fails or a background task misses a scheduled ping. This type of software is for system administrators and developers who need to detect outages before users report them. Self-hosting these apps ensures that monitoring logs and incident history remain on private infrastructure. This approach allows you to manage status pages and network latency checks without relying on external service providers.
This page lists 17 open source tools in the Uptime Monitoring category. The most popular are Uptime Kuma, changedetection.io and Gatus. Most use the MIT or Apache-2.0 license, and 16 offer an official Docker image.
