Features

We bring all the tools into one place to give you everything you need to build better products:

• Event-based Analytics on users or groups - capture your product's usage data to see which users are doing what in your application
• Product data visualizations graphs, funnels, cohorts, paths, retention, and dashboards
• Complete control over your data - host it yourself on any infrastructure
• Session recording to watch videos of your users' behavior, with fine-grained privacy controls
• Automatically capture clicks and pageviews to analyze what your users are doing without pushing events manually
• Feature flags to understand the impact of new features before rolling them out more widely
• Heatmaps to understand how users interact with your product with the PostHog Toolbar
• Automated Analysis to find correlations between successful users and their behaviors or attributes
• Plays nicely with data warehouses import events or user data from your warehouse by writing a simple transformation plugin, and export data with pre-built plugins - such as BigQuery, Redshift, Snowflake and S3
• Infinitely extensible use custom plugins to extend PostHog and integrate with any service or tool
• Ready-made libraries for JS, Python, Ruby, Node, Go, Android, iOS, PHP, Flutter, React Native, Elixir, Nim + an API for anything else
• And much much more... for a full list of PostHog features.

Event autocapture

You don't have to spend weeks instrumenting every event on your front-end, point and click at elements from your browser and turn them into events which you and your team can analyze

Philosophy

We help you understand user behavior and build better products without losing control of your data.

In our view, third-party analytics tools do not work in a world of cookie deprecation, GDPR, HIPAA, CCPA, and many other four-letter acronyms. PostHog is the alternative to sending all of your customers' personal information and usage data to third-parties.

PostHog is designed to give you every tool you need to understand user behavior, create hypothesis and release changes to make your product more successful.

What's cool about this?

PostHog is the only product-focused open-source analytics suite, with an event, user and group architecture that you can host in any infrastructure.

We are an open-source alternative to products such as Mixpanel, Amplitude, Heap, HotJar, Pendo or Full Story. We're designed to be more developer-friendly, with the broadest range of features like session recording, heatmaps, feature flags, and plugins.

We play nicely with data warehouses and other services - you can import event or user data by writing a plugin to create transformations, or you can export data by using our existing data exports to BigQuery, Redshift, Snowflake, etc. All without losing control of your data.
