Replace Datadog with self-hosted monitoring. Compare Grafana, Uptime Kuma, and Prometheus — no per-host pricing, unlimited metrics.
Datadog charges $15-$23/host/month and costs scale rapidly. Grafana + Prometheus is the industry-standard open-source stack used by companies like Uber and Stripe. Uptime Kuma is perfect for simple uptime monitoring with beautiful status pages.
Prometheus collects and stores metrics from your applications. Grafana visualizes those metrics in dashboards. Together they replace most Datadog functionality for free.
