PostHog
Open-source product analytics, session replay, and feature flags
What is PostHog?
PostHog is the open-source product analytics platform that bundles analytics, session replay, feature flags, A/B experiments, surveys, and an LLM observability product into one developer-first tool. Unlike Mixpanel or Amplitude, PostHog can be self-hosted (on your own AWS) or used as Cloud, with the same product code being open source on GitHub. The pricing model is usage-based with generous free tiers across every product. PostHog's CDP (Data Pipelines) syncs events to warehouses and tools. AI features include LLM Observability and AI-generated SQL via Max. The product is particularly strong for engineering-led startups who want one tool for analytics + flags + replay rather than separate Mixpanel + LaunchDarkly + FullStory.
PostHog offers a freemium pricing model starting at $0/month. A free tier is available with limited features. Platform availability information is not currently listed.
