Data & Analytics

An open-source alternative to Amplitude

PostHog is the one project in our catalog listed as a replacement for Amplitude. It is analytics software with 40.5K GitHub stars. Below is how it measures against the questions people usually ask first.

PostHog

Analytics

Product analytics, session replay and feature flags in one platform.

PostHog brings the tools a product team uses to understand and improve its product into one place. Analytics, recordings, feature releases and customer feedback share the same data, so each question can be answered without stitching together separate services.

  • Analyse product and web traffic with autocapture, funnels and SQL.
  • Watch session replays and heatmaps to see how people really use your product.
  • Roll out changes safely with feature flags, experiments and in-app surveys.

What people use it for

Find where users drop off

Capture events automatically, build funnels and query the data with SQL to see which steps of sign-up or checkout lose the most people.

See what went wrong in a session

Watch session replays and heatmaps alongside tracked errors to understand a confusing page or a bug that customers report.

Launch a feature to a small group first

Release a change to selected users with feature flags, measure its effect with an experiment, and ask for feedback with an in-app survey.
