The Verdict
Grafana is built for devops teams and sre teams, with a focus on dashboards and data-sources. Prometheus targets devops engineers and sre teams and leads with metrics-collection and alerting.
Prometheus uses custom enterprise pricing, while Grafana starts at $29/mo — a tangible advantage for teams with a fixed budget.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, Grafana offers broader built-in capabilities (8 features vs 6), while Prometheus takes a more focused approach — which can mean a simpler, faster onboarding experience.
Both tools are a solid fit for sre teams — in those cases, the decision often comes down to workflow style and how your team prefers to organize work.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
