Heap (Contentsquare)
About the product analytics category
Product Analytics platforms in 2026 span transparent usage pricing (PostHog) to opaque enterprise custom-quotes (Pendo, Heap Pro/Premier). Published rates: PostHog pay-as-you-go ($0.00005/event after 1M free, $0.005/recording after 5K free, $0.0001/feature flag request after 1M free — industry's most transparent pricing), Mixpanel Growth ($0 for first 1M events, then $0.28 per 1K events up to 20M), Amplitude Plus ($49/month starting for 300K MTUs + 25M events). Custom-quote only: Heap Growth/Pro/Premier (acquired by Contentsquare 2024), Pendo Base/Core/Ultimate (all custom pricing). Free tiers: Mixpanel 1M events + 5 reports + 10K session replays, Amplitude 10K MTUs + 10M events + session replay, Heap 10K sessions + core charts, PostHog 1M events + 5K recordings + 1M feature flag requests + 100K exceptions + 1.5K survey responses (most generous free tier in category), Pendo 500 MAUs (most restrictive free tier). Major 2024 M&A: Heap acquired by Contentsquare (completed 2024) — Heap now operates as product analytics product line within Contentsquare's broader digital experience platform. Mixpanel + Amplitude remain independent public SaaS companies with transparent pricing for mid-market tiers. PostHog (founded 2020) has emerged as the open-source challenger with fully transparent unit pricing across all products (product analytics + session replay + feature flags + experiments + data warehouse + error tracking + surveys + LLM analytics) — YC-backed, growing rapidly among tech-forward SaaS companies. Pendo (founded 2013) differentiated from pure product analytics into digital adoption platform territory with in-app guides + NPS + sentiment surveys — competes with Gainsight Product Experience + WalkMe. Startup programs: Mixpanel offers first year free on Growth plan for companies under 5 years + under $8M funding; Amplitude offers one free year on Growth plan for startups under $10M funding + under 20 employees. Typical product analytics deployment tracks: user events (clicks, page views, feature usage), user properties (demographics, plan tier, cohort), funnels (conversion paths), retention curves, behavioral cohorts, path analysis.
How to choose between product analytics options
First: event volume + user counts? Under 1M events/month + under 10K MAUs: Mixpanel Free or PostHog Free (both generous). 1M-20M events + 10K-300K MAUs: Mixpanel Growth ($0.28/1K events) or Amplitude Plus ($49/mo starting) or PostHog pay-as-you-go. 20M+ events: contact sales for Mixpanel Enterprise, Amplitude Growth/Enterprise, or negotiate PostHog volume. Second: transparent vs custom pricing preference? PostHog is only vendor with fully transparent per-unit pricing across all tiers — no sales contact required for any scale. Mixpanel + Amplitude transparent for entry + mid-market, custom above. Heap + Pendo opaque at all tiers except free. For procurement simplicity + no-sales-contact preference: PostHog. For predictable tier pricing: Mixpanel Growth or Amplitude Plus. Third: product suite breadth needed? Pure product analytics only: Mixpanel or Amplitude (category leaders, deepest analytics feature sets). Product analytics + session replay + feature flags + experiments + surveys + error tracking unified: PostHog (most comprehensive suite) or Amplitude (analytics + experimentation + session replay). Product analytics + in-app guides + NPS/sentiment surveys for customer onboarding: Pendo (digital adoption platform focus). Product analytics + session replay + digital experience: Heap/Contentsquare (broader DX platform post-acquisition). Fourth: open-source + self-hosted deployment? PostHog is only open-source option with self-hosted deployment for data sovereignty/security requirements. All others cloud-only. Fifth: startup programs? Mixpanel first year free Growth plan (under 5 years + under $8M funding + no prior redemptions). Amplitude one free year Growth plan (under $10M funding + under 20 employees). Meaningful for post-Seed/Series A with 6-18 month runway — saves $10K-50K year-one. Sixth: session replay inclusion? PostHog pay-as-you-go ($0.005/recording after 5K free). Mixpanel Growth (20K recordings/month included free). Amplitude Starter (session replay included). Heap Pro+ (add-on pricing). Pendo Core+ (session replay custom-priced). Mixpanel + Amplitude + PostHog most transparent for session replay. Seventh: data warehouse + ETL integration? PostHog Data Warehouse ($0.000015/row after 1M free — most affordable). Amplitude real-time streaming/syncs (Growth+). Heap Premier data warehouse integration. Mixpanel data integrations (Growth+). Pendo Data Sync (Ultimate only).
