PostHog is an all-in-one, open-source platform for building better products. It combines product analytics, web analytics, session replay, feature flags, A/B testing, surveys, error tracking and a data warehouse in one place, so engineering and product teams don't need to stitch together many separate tools.
PostHog is popular with startups and developers because it is transparent, developer-friendly and can be self-hosted or used in the cloud. Its AI assistant, Max, can answer questions about your product data, build insights and help write SQL, and LLM analytics help teams monitor their own AI features. Usage-based pricing with a generous free tier lets small teams start without a big bill.
Good fit if you: are a startup or product team that wants analytics, experiments and session replay in one developer-friendly tool.
Less ideal if you: want a simple marketing dashboard with no setup; PostHog is built for product and engineering teams.
Pricing: generous free tier every month; usage-based pricing beyond that.
