24 alternatives to Kuvasz – an open-source uptime and SSL monitoring service
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…

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. It still has some rough edges and needs to mature, but I wanted to share it with the world now—perhaps someone else will find it useful and be willing to help me develop it by testing or providing…

Eurker▲16Hi HN, I built an uptime monitoring tool similar to other services, but more lightweight, easier to set up, and focused on developer flexibility. It includes all the essential features — keyword assertions, custom HTTP methods, retries, alerts via SMS/Email/Slack/Webhooks — with a clean JSON config system for advanced setups. I originally made it last month to learn more about Firebase Cloud Functions and Cloud Run, and to build something real for my portfolio. It turned out to be genuinely useful, so I’ve decided to share it. Would love your feedback – especially from devs…
