Datadog is published by Datadog. This page compares only projects with an explicit relationship to it; shared categories alone never create an alternative claim.
Recommended order uses OpenAlternative organic alternatives v4 (version 4). Relationship confidence, category fit, logarithmic popularity, as-of maintenance and freshness, bounded anomaly quarantine, and known-data penalties. Payment is fixed at zero.
A hard constraint removes a Project only when its stored fact is known and conflicts. Unknown facts remain visible, are called out below, and never become a negative claim.
Self-hosted uptime monitoring with a clean status page
Uptime Kuma monitors HTTP endpoints, TCP ports, containers, and certificates, and notifies through almost a hundred channels. Setup is a container and a few minutes.
Dashboards over whatever data you already store
Grafana is the visualisation layer that sits above other systems rather than a monitoring stack of its own. It queries Prometheus, Loki, PostgreSQL, ClickHouse, and dozens of other sources, and puts them on the same dashboard.
Groups appear only when at least two credible projects qualify.
