Products that do what Kuvasz – an open-source uptime and SSL monitoring service does

A few months ago I took out my side project - an uptime & SSL monitoring service - from the drawer. I've decided to give it a new life and completely overhauled it, added a lot of new feature, and most importantly, a UI. Highlights - configurable uptime & SSL monitoring - Telegram, Slack, PagerDuty & E-mail notifications (more to come!) - fully-fledged REST API - a responsive, modern & fast UI - monitors are optionally configurable via a single YAML file, or you can choose to use either the UI or the API to maintain them - Cloud-native, distributed as amd64 and arm64 images - Only one…

Prometheus and OTLP support in Kuvasz, an open-source uptime monitor▲6
I've added Prometheus and OpenTelemetry support to my beloved open-source pet project called Kuvasz, which is a cloud-native, feature-rich uptime & SSL monitoring service, written in Kotlin. If you already have an observability stack and you only need a free uptime/SSL monitor, you can easily integrate Kuvasz with it. Let me know what you think or what you miss from Kuvasz!

Kula – Lightweight, self-contained Linux server monitoring tool▲93
Zero dependencies. No external databases. Single binary. Just deploy and go. I needed something that would allow for real-time monitoring, and installation is as simple as dropping a single file and running it. That's exactly what Kula is. Kula is the Polish word for "ball," as in "crystal ball." The project is in constant development, but I'm already using it on multiple servers in production.
