PostHog
Open-source product analytics, session replay, feature flags, and surveys in one stack.
PostHog is an open-source product OS that bundles product analytics, session replay, feature flags, experiments, and surveys into a single platform. Pricing is usage-based per product with a generous free tier (1M events/mo, 5K recordings/mo, 1M flag requests/mo, 1.5K survey responses/mo) and pay-as-you-go rates above that, with steep volume discounts at scale. Boost ($250/mo), Scale ($750/mo), and Enterprise ($2,000/mo) are platform add-ons that layer on enhanced support, RBAC, and SLAs. You can also self-host the entire stack for free if you want full control.

Where PostHog earns its price
- Genuinely open-source: you can self-host the entire stack for free with no feature gating
- Unified analytics, session replay, feature flags, and surveys in one tool (most competitors charge separately for each)
- Generous free tier (1M events, 5K recordings, 1M flag requests, 1.5K survey responses per month) covers most early-stage use
- Transparent usage-based pricing with steep volume discounts at scale
- Modern developer experience with strong SDKs, clean APIs, and active engineering blog
Where it falls short
- Pay-as-you-go can spike unpredictably with viral traffic or instrumentation mistakes (no built-in monthly cap by default)
- Add-on pricing ($250 to $2,000) is opaque about exactly what each tier unlocks beyond support and RBAC
- Smaller third-party integrations ecosystem than Mixpanel or Amplitude
- Self-hosted deployment requires real infrastructure work (Kubernetes, ClickHouse, ongoing ops)
Best for
- Technical product teams that want one tool covering analytics, experiments, replay, and surveys
- Startups under 1M events per month, where the free tier covers the entire stack
- Companies committed to open-source infrastructure who want the option to self-host
Not for
- Marketing-only teams who need attribution and campaign analytics (Mixpanel or GA4 fit better)
- Enterprises with strict procurement that requires a SaaS-only vendor with no self-hosted option in scope
- Non-technical users who cannot navigate event-based analytics UIs and SQL-style insights
