The Verdict
n8n is built for developers and technical teams, with a focus on workflows and self-hosting. Prometheus targets devops engineers and sre teams and leads with metrics-collection and alerting.
Prometheus uses custom enterprise pricing, while n8n starts at $24/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, n8n 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.
