Frequently asked
Prometheus alternatives FAQ
- Is Prometheus free?
- Yes. Prometheus is free and open source with no licence fee, and it is hosted by the Cloud Native Computing Foundation. You self-host it, so your costs are the servers to run it on and the time to operate it, not a subscription.
- What is the best Prometheus alternative?
- It depends on what is limiting you. VictoriaMetrics is the closest drop-in for teams hitting cardinality or retention limits, because it speaks PromQL and can act as a Prometheus-compatible backend. InfluxDB is the alternative if you need a general time-series database, and Netdata is the choice if you want monitoring that works with no configuration at all.
- Is Grafana a replacement for Prometheus?
- No. Prometheus collects, stores, and alerts on metrics; Grafana visualises data from sources like Prometheus. They are usually deployed together, and Grafana on its own cannot replace Prometheus because it stores no data itself.
- Can I migrate from Prometheus to VictoriaMetrics?
- Usually with moderate effort. VictoriaMetrics is PromQL-compatible and can act as a Prometheus-compatible remote storage backend, so existing exporters and queries often carry over. The work is migrating stored data and repointing dashboards and alert rules.
