About PostHog

PostHog is an open-source product analytics platform that combines event tracking, user session recordings, heatmaps, feature flags, A/B experimentation, and in-app surveys in one self-hostable package. The cloud-hosted version offers a generous free tier of 1 million events per month; self-hosting on your own infrastructure is free with no usage limits. PostHog's autocapture automatically records user interactions without manual event instrumentation. SDKs cover JavaScript, React, Python, iOS, Android, and more. Its all-in-one approach eliminates the need to stitch together Mixpanel, FullStory, LaunchDarkly, and Optimizely. It is the preferred product analytics stack for developer-led companies and privacy-conscious product teams who want full ownership of their user data.
