Prometheus alternatives: 5 apps ranked by verified data
Common reasons people leave Prometheus: no built-in long-term or clustered storage, and metrics only, so logs and traces need other tools. We ranked 5 alternatives by how directly each one replaces Prometheus, then by reviews, real visits and how recently each app's facts were checked against its own website. Datadog currently ranks first.
