Decision by scenario

Autocapture and retroactive analysis

Both products autocapture common interactions and let teams add meaning later. Heap makes that workflow more central; PostHog connects the resulting definition to a wider product-engineering platform.

Missing-event investigation

From an untracked release question to a durable metric

1. 1ReleaseShip the interface change.
2. 2Untracked interactionA new question appears.
3. 3Automatic evidenceCheck retained captured behavior.
4. 4Semantic reconstructionDefine the interaction over that evidence.
5. 5Server outcomeConfirm whether the business action succeeded.
6. 6ReplayInspect the surrounding session when retained.
7. 7Future instrumentationAdd a stable semantic or server event.

PostHog path

Raw event → ActionApply a reusable definition to retained captured events.

Heap path

Captured interaction → visual definition or repairLabel the interaction, inspect history, and repair the definition when the interface changes.

Hard limit: If the interaction, required property, error, or outcome was not captured—or the data expired—it cannot be reconstructed retroactively.

Analytics, replay, and B2B accounts

Both support funnels, retention, reusable audiences, paths or journeys, and replay-linked investigation. Heap’s visual definitions and Journeys favor experience-led exploration. PostHog’s cohorts, insights, and replay favor workflows that continue into flags, experiments, errors, and engineering context.

An account funnel answers whether anyone at a company completed the steps. It does not automatically reveal adoption breadth, user penetration, or champion concentration. Define those separately and inspect the sessions behind material changes. See account vs user adoption and session replay vs product analytics.

Product platform and deployment

PostHog extends beyond analytics into feature delivery, experiments, surveys, errors, logs, AI/LLM observability, warehouses, pipelines, destinations, and workflows. Heap is part of Contentsquare’s broader digital-experience environment, while standalone Heap packaging emphasizes analytics and sells major capabilities such as Experience Analytics, Error Analysis, Heap Connect, and Activate through plan/add-on entitlements.

PostHog’s consolidation can reduce context switching, but each product needs an owner, privacy model, meter, retention rule, and maturity test. Heap’s focused experience workflow can be easier for product teams, but sales-led packaging means buyers must make entitlements and limits explicit in the quote.

Platform layers

What is native, separately metered, or externally supplied?

Platform layers and packaging

Layer	PostHog	Heap by Contentsquare
Collection	Native	Native
Analytics	Native	Native
Replay	Native but separately metered	Add-on
Experiments	Native	Third-party integration
Flags	Native	Not identified in current public packaging
Surveys	Native but separately metered	Wider ecosystem or separate contract
Errors	Native but separately metered	Add-on
Warehouse	Native but separately metered	Add-on
Automation	Native but separately metered	Add-on

For deployment, PostHog Cloud is the documented recommendation for most organizations. The open-source self-hosted path is labeled a hobby deployment without support or guarantees, and paid-plan features are Cloud-only. Heap has no public self-hosted application offering. Self-hosting also does not create compliance automatically: minimization, masking, access, deletion, backups, monitoring, and incident response remain necessary.

Pricing and customer ratings

Pricing and rating data was verified August 9, 2026. PostHog exposes many public meters; Heap exposes a free allowance and session-based packaging, while most paid dollar rates and major add-ons require a quote.

Detailed pricing cautions

PostHog’s first paid rates differed by anonymous versus identified analytics events and by each product meter. A Heap quote should specify session calculation, environments, history, Account-Based Analytics, Experience Analytics, replay sampling and retention, Error Analysis, Heatmaps, Connect, Activate, regions, support, overages, and contract minimums. Compare the same workload and count implementation, governance, privacy, warehouse, training, and companion tools.

Ratings are directional signals, not benchmarks. Use themes to define a proof of concept; they cannot prove security, performance, data correctness, contract quality, or fit at your scale.

Which should you choose?

Pilot the same missed-event investigation, funnel, retention cohort, account analysis, replay diagnosis, and governance repair. Measure time to a trusted answer, maintenance after a UI change, privacy controls, and total operating cost.

Where Hymetry fits

Hymetry is narrower account-centric product intelligence for B2B SaaS. It fits when teams need to understand how Companies and their Users adopt grouped Pages or product areas, how broad and concentrated that adoption is, and which Visits explain a signal.

Frequently asked questions

Which has stronger autocapture?

Heap makes autocapture, visual definition, history, and repair the center of its product workflow. PostHog also autocaptures common web interactions and supports retrospective Actions, but its center of gravity is the broader engineering platform.

Can both define events retroactively?

Yes, over retained evidence. PostHog Actions can classify previously captured raw events; Heap can label captured interactions and repair definitions. Neither can recover a property, business outcome, or session that was never captured or has expired.

Which has better session replay?

PostHog connects replay to engineering evidence such as flags and errors. Heap connects replay to Journeys, heatmaps, friction, and experience analysis. Test the exact web/mobile framework, masking, search, retention, and plan entitlement.

Which includes feature flags and experiments?

PostHog includes native flag delivery and experiment analysis billed through flag requests. Heap can analyze externally supplied experiment variants but no comparable native standalone flag-delivery product was identified in current public packaging.

Which supports B2B account analytics?

Both do through paid packaging: PostHog Group Analytics and Heap Account-Based Analytics. Both need stable company context. Neither automatically calculates adoption breadth, user penetration, or champion concentration without deliberate definitions.

Which can be self-hosted?

Only PostHog has a documented self-host path, and its own guidance labels it an unsupported hobby deployment without guarantees; paid-plan features are Cloud-only. No public self-hosted Heap application was found.

Disclosure: Hymetry publishes this comparison and appears only where its narrower B2B account model is relevant. Ownership, product claims, prices, ratings, and video metadata were verified August 9, 2026 and may change.

Methodology and evidence limits

Official PostHog, Heap, and Contentsquare product, pricing, implementation, privacy, and deployment documentation was prioritized. G2 supplied the shared rating source. Vendor and commercial-agency videos provide disclosed workflow orientation only.

No authenticated tenant, quote, or performance benchmark was used. Heap paid dollar pricing remains quote-based, and PostHog rates are point-in-time references.
