What is PostHog?

Open-source, all-in-one product analytics platform combining event tracking, session replay, feature flags, A/B testing, surveys, error tracking, and a data warehouse — with self-hosting option for complete data control.

PostHog is an open-source product analytics platform for product, growth, and engineering teams that combines event tracking, session replay, feature flags, A/B testing, surveys, error tracking, and a data warehouse, with freemium cloud pricing and self-hosting for teams that need more data control. Based on the provided website metadata, it combines event tracking, product analytics, session replay, feature flags, A/B testing, surveys, error tracking, and a data warehouse into a single platform. This makes it especially relevant for teams that want to understand how users behave inside a product, investigate user sessions, ship controlled feature releases, run experiments, collect feedback, monitor errors, and analyze product data without stitching together many separate tools.

A core distinction of PostHog is that it is open source and offers a self-hosting option. For organizations that care about data control, deployment flexibility, or avoiding a fully closed analytics vendor, that is a meaningful part of the product’s positioning. The self-hosting option can be useful for teams with stricter privacy, compliance, or infrastructure requirements, while the freemium model gives smaller teams a way to start using the platform without committing to a paid plan immediately.
