PostHog (Product Analytics)

Open-source product analytics + flags + replay + experiments unified.

By PostHog, Inc. · Founded 2020 · London, UK / San Francisco, CA · private

PostHog is the open-source product analytics platform, founded 2020 (YC W20). Last valued ~$2B (2025 Series D rumored, not officially disclosed). The product uniquely combines product analytics + feature flags + session replay + experiments + surveys + LLM observability in one platform, the broadest scope among modern product analytics vendors. Open-source self-host option (80,000+ deployments) plus PostHog Cloud. Strengths: open-source self-host alternative for privacy-first orgs, unified platform reduces tool sprawl, transparent public roadmap and engineering culture, aggressive feature velocity, strong fit for engineering-led teams, transparent flat-rate pricing, and rapidly closing feature parity with Amplitude on cloud product. Best fit for engineering-led teams wanting unified platform and modern open-source alternative. Trade-offs: governance and access controls below Amplitude at enterprise scale, product analytics depth still slightly behind Amplitude on advanced cohort analysis, customer support model is community-led (slower than enterprise SaaS), and self-host requires real engineering resources.
