Frustrated by expensive per-seat pricing and unfriendly contract terms, we looked for PagerDuty alternatives and found a fantastic open-source project called Uptime Kuma: https://github.com/louislam/uptime-kuma
Uptime Kuma is one of the few open-source projects that feels like a commercial product: polished user experience, frequent release cadence, and a rich set of features including monitoring PostgreSQL servers, Docker containers, and so much more. Its list of supported notification services is so long that I don't even recognize half of the options available. Truly impressive.
Side note and shameless plug… We love Uptime Kuma so much that we made it one of the cornerstone applications provided by Fortressa, which we think of as the “App Store for Open Source”: https://fortressa.com/
