The Verdict
CockroachDB is built for distributed applications and fintech, with a focus on distributed-sql and multi-region. Prometheus targets devops engineers and sre teams and leads with metrics-collection and alerting.
Prometheus uses custom enterprise pricing, while CockroachDB starts at $0/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, CockroachDB offers broader built-in capabilities (7 features vs 6), while Prometheus takes a more focused approach — which can mean a simpler, faster onboarding experience.
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.
