Open-source product analytics, replays, flags, and more.
PostHog is an all-in-one product analytics platform built for engineering and product teams that would rather have one open-source tool than stitch together five. Instead of buying separate products for analytics, session replay, feature flags, experiments, and surveys, PostHog bundles them together on a single platform, so you can see what users do, watch replays of how they did it, ship features behind flags, run A/B tests, and ask users questions — all connected to the same event data.
It is developer-first and transparent: PostHog is open-source (you can self-host the whole thing) and has a famously clear, usage-based pricing model with a genuinely generous free tier — you pay only for what you use per product (events, recordings, flag requests), with steep volume discounts and no per-seat charges, so whole teams can use it freely. That combination of an all-in-one suite, open-source code, and pay-for-what-you-use pricing made it a fast-growing favorite among startups.
PostHog suits product, growth, and engineering teams that want product analytics plus replays, flags, and experiments in one place, especially technical teams that value open-source and usage-based pricing. Its free tier keeps entry cost at zero, and pay-as-you-go scales with usage.
