The Verdict
Microsoft Clarity is built for small businesses and startups, with a focus on session-recordings and heatmaps. Prometheus targets devops engineers and sre teams and leads with metrics-collection and alerting.
Both tools use custom enterprise pricing — you'll need to contact sales for a quote, which makes direct cost comparison difficult.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, Microsoft Clarity 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.
