About PostHog
PostHog is an open-source product analytics platform founded in 2020 by James Hawkins and Tim Glaser and backed by Y Combinator. Its strategy is to give engineering-led companies every product tool in one place: event analytics, web analytics, session replay, feature flags, A/B experiments, surveys, error tracking, a data warehouse and LLM observability, all sharing the same user and event data.
PostHog is built for engineers. Autocapture and SDKs for web, mobile and backend platforms collect events, HogQL gives SQL access to everything, and a CDP pipeline sends data to other tools. Replays connect to events, errors and flags, so you can watch exactly what a flagged cohort experienced. Each product is priced by usage with a generous monthly free allowance, so small teams often pay nothing, and billing limits prevent surprises; optional add-ons add support SLAs, SSO, advanced permissions and longer retention. Cloud hosting is available in the US and EU, and self-hosting is supported for small deployments.
PostHog fits startups and scale-ups that want to replace separate analytics, replay, flag and experimentation vendors with one transparent bill. The interface is dense, and costs need monitoring when many products scale at once. Amplitude and Mixpanel offer deeper analytics experiences for large product organizations, LaunchDarkly is more mature for enterprise feature management, and Plausible or Google Analytics suit marketing teams that only need website traffic reports.
