Event autocapture


Many engineers find it painful to work out how their products are being used. This makes design decisions tough. PostHog solves that.

We also strongly believe 3rd party analytics don't work anymore in a world of Cookie laws, GDPR, CCPA and lots of other 4 letter acronyms. There should be an alternative to sending all of your users' personal information and usage data to 3rd parties.

PostHog gives you full control over all your users' data, while letting anyone easily perform powerful analytics.

It means you can know who is using your app, how they're using, and where you lose users in the sign up process.

What's cool about this?

PostHog is the only product-focused open source analytics library, with an event and user-driven architecture. That means tracking identifiable (where applicable) user behavior, and creating user profiles. We are an open source alternative to Mixpanel, Amplitude or Heap, designed to be more developer friendly.

There are a couple of session-based open source libraries that are nice alternatives to Google Analytics. That's not what we are focused on.
