How pricing works
These two tools don't price the same way, so the headline numbers below aren't directly comparable until you plug in your own volume.
- Heap (Unknown model) — Heap bills on a fixed plan from $300/mo, so the listed price is what you pay regardless of volume.
- PostHog (Per Usage) — PostHog bills purely on usage — Free up to 1M events/mo, then usage-based. There is no fixed per-seat fee, so the monthly cost depends entirely on how much you consume.
Per-minute, per-credit and per-token rates exclude any downstream model, speech or telephony costs unless the vendor states otherwise.
Product analytics that captures every click, tap, and swipe automatically — positioned as the alternative to Amplitude/Mixpanel for teams that don't want to define events upfront. Distinctive for autocapture (retroactive analysis of any user interaction). Acquired by Contentsquare in 2024. Free tier up to 10K sessions/mo; Growth ~$300/mo ($3,600/yr); Enterprise typically $30K-100K/yr. Popular with product teams who value 'ask any question later' over structured tracking.
Open-source product analytics + feature flags + session replay + surveys, positioned as the all-in-one alternative to Mixpanel + LaunchDarkly + FullStory + Typeform. Distinctive for self-hostable free tier (unlimited events on your infra) and its "we're the open-source everything" positioning. Cloud priced free-$450+/mo based on events + recordings. Popular with technical founders who don't want to stitch 4 tools together and prefer OSS over vendor lock-in.

What each is best for
Heap is worth it if… product/growth teams (10-500 people) that want autocapture-based analytics — no manual event instrumentation — particularly if your engineering team is too busy to build tracking taxonomies. Growth covers small teams; Pro and Premier custom for larger orgs.
PostHog is worth it if… product/growth teams that want product analytics + session replay + feature flags + A/B testing + surveys in one open-source platform — particularly if you value self-host option and pay-as-you-go pricing. Free tier includes 1M events + 5K replays/mo; pay-as-you-go beyond; add-ons for SSO/security/data warehouse.
Bottom line: Similar positioning, closer to a preference call than a strategic one.
