Posthog

PostHog is an open-source product analytics suite, built for developers. Automate the collection of every event on your website or app, with no need to send data to 3rd parties.

You can deploy on your own infrastructure, and PostHog plays nicely with data warehouses through plugins for import, transformation, and export.

• Session recording to watch videos of your users' behavior, with fine-grained privacy controls.

Philosophy

We help you understand user behavior without losing control of your users' data.

In our view, third-party analytics do not work anymore in a world of cookie laws, GDPR, 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.

This means you can know who is using your app, how they're using it, and where you lose users, among many other things.

Our features help you: (i) understand user behavior, (ii) create hypotheses for what to build next, and (iii) release changes to your product, then go back to step (i).

What's cool about this?

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

We are an open-source alternative to products such as Mixpanel, Amplitude, or Heap, that's designed to be more developer-friendly, with a broader range of features like session recording, heatmaps, feature flags, and plugins.

We play nicely with data warehouses - 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. Uniquely, you can host PostHog in the same infrastructure.
