Gatus is an open source tool for uptime monitoring and status pages, aimed at developers and operations teams. You describe in a configuration file which endpoints to check and which conditions apply; Gatus shows the results on a status page and can send alerts through several channels, such as Telegram and Zulip. It is installed by you, for example as a container, and is listed in Sweden's public-sector software catalogue, offentligkod.se.
Gatus has no company or foundation behind it: the repository sits under the account of an individual developer whose GitHub profile gives Canada as the location. The project is therefore outside the EU. The licence is Apache-2.0 and development is active; the latest changes in the repository date from October 2026. Because you host Gatus yourself, monitoring data stays on your own infrastructure. According to the developer's profile, a hosted service is being built at gatus.io; no further details were published there.
