About this project

PostHog is an open source product analytics suite that combines event analytics, funnels, session replay, feature flags, A/B testing, and surveys in one platform. It's a developer-friendly, self-hostable alternative to stitching together Amplitude, LaunchDarkly, and Hotjar — giving product teams everything they need to understand and improve their apps.

How to use it

Get started

Hosted: Sign up at posthog.com and add the snippet:

<script>
  !function(t,e){/* posthog-js init */}(document,window);
  posthog.init('YOUR_KEY', { api_host: 'https://us.i.posthog.com' });
</script>

Self-host: Use the Docker Compose / Helm deployment for full control over your event data.
