The Verdict
Datadog is built for devops teams and sre teams, with a focus on infrastructure-monitoring and apm. Heap targets product teams and growth marketers and leads with auto-capture and session-replay.
Heap uses custom enterprise pricing, while Datadog starts at $15/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, Datadog offers broader built-in capabilities (8 features vs 7), while Heap 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.
