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.

PostHog data pipelines now bill by rows exported and trigger events
From September 11, 2025 PostHog bills data pipelines on rows exported and trigger events instead of all events ingested. The monthly free allowances are 10,000 trigger events and 1 million rows exported; usage up to the previous day was billed under the old scheme.
PostHog adds cheaper anonymous events to product analytics pricing
On August 1, 2024 PostHog announced separate pricing for identified and anonymous events in product analytics; until then every event was charged the same. Identified events cost the same as before; the company said anonymous events are between 55% and 80% cheaper for most customers and will soon become the default.
