The Verdict
Heap is built for product teams and growth teams, with a focus on auto-capture and retroactive-analytics. PostHog targets developers and startups and leads with product-analytics and session-replay.
Heap uses custom enterprise pricing, while PostHog 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, PostHog offers broader built-in capabilities (7 features vs 6), while Heap takes a more focused approach — which can mean a simpler, faster onboarding experience.
Both tools are a solid fit for product 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.
