About Posthog
PostHog is an open-source product analytics platform that uniquely combines product analytics, session recordings, feature flags, A/B testing, and a data warehouse in a single self-hostable tool. Founded in 2020 by James Hawkins and Tim Glaser and backed by Y Combinator, PostHog has become the fastest-growing product analytics platform in the developer community with over 50,000 companies using it. The platform's open-source nature and self-hosting option give engineering teams complete data control — critical for companies with strict data residency requirements. PostHog Cloud is generous: the free tier includes 1 million events, 5,000 recordings, and 1 million feature flag requests per month. After that, pricing is pay-per-use at competitive rates. PostHog's product philosophy is 'all your product data in one place' — replacing separate tools for analytics (Mixpanel), session recording (Hotjar), feature flags (LaunchDarkly), and A/B testing (Optimizely) with a single integrated platform. The developer experience is exceptional, with SDKs for every major language, a GraphQL API, and direct SQL access via PostHog's built-in data warehouse.
Frequently Asked Questions
Is PostHog free?
PostHog Cloud has a generous free tier: 1 million product analytics events, 5,000 session recordings, 1 million feature flag requests, and 1 million A/B testing events per month at no cost. Beyond these limits, pay-as-you-go pricing applies. Self-hosting PostHog Community Edition is completely free with no limits beyond your server capacity.
PostHog vs Mixpanel: which is better?
PostHog is better for engineering-led teams that want open-source, self-hosting, feature flags, and A/B testing alongside analytics in one platform. Mixpanel is better for product teams without strong engineering support who want an easier setup and more polished UI. PostHog's pricing is more predictable at scale; Mixpanel's interface is more accessible for non-technical users.
Can you self-host PostHog?
Yes, PostHog Community Edition is open-source and can be self-hosted on any infrastructure. Deployment is supported on AWS, GCP, Azure, DigitalOcean, and Render via Docker Compose or Helm charts. Self-hosting gives complete data ownership, no event limits, and eliminates third-party data transfer — ideal for GDPR compliance and companies with strict data residency requirements.
