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 third-parties.
You can deploy on your own infrastructure, and PostHog plays nicely with data warehouses through plugins for import, transformation, and export.
## Quick start
It's easy and free to get started.
Deploy PostHog Self-Hosted in your existing infrastructure.
... or use [PostHog Cloud](https://app.posthog.com/signup) if you don't need to self-host.
## Features
- **Event-based** analytics at a user level - capture your product's usage data to see which users are doing what in your application.
- **Product data visualizations**: [graphs](https://posthog.com/docs/features/trends), [funnels](https://posthog.com/docs/features/funnels), [user cohorts](https://posthog.com/docs/features/cohorts), [user paths](https://posthog.com/docs/features/paths), [retention tables](https://posthog.com/docs/features/retention), and [dashboards](https://posthog.com/docs/features/dashboards).
- **Complete control** over your data - [host it yourself](https://posthog.com/docs/self-host/overview#deploy) in any infrastructure.
- **Session recording** to [watch videos](https://posthog.com/docs/features/session-recording) of your users' behavior, with fine-grained privacy controls.
- **Automatically capture** [clicks and pageviews](https://posthog.com/docs/features/actions) 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** with the [PostHog Toolbar](https://posthog.com/docs/features/toolbar).
- **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.
- **Ready-made libraries** for **[JS](https://posthog.com/docs/integrations/js-integration), [Python](https://posthog.com/docs/integrations/python-integration), [Ruby](https://posthog.com/docs/integrations/ruby-integration), [Node](https://posthog.com/docs/integrations/node-integration), [Go](https://posthog.com/docs/integrations/go-integration)**, [Android](https://posthog.com/docs/integrations/android-integration), [iOS](https://posthog.com/docs/integrations/ios-integration), [PHP](https://posthog.com/docs/integrations/php-integration), [Flutter](https://posthog.com/docs/integrations/flutter-integration), [React Native](https://posthog.com/docs/integrations/react-native-integration), [Elixir](https://posthog.com/docs/integrations/elixir-integration) + an [API](https://posthog.com/docs/integrations/api) for anything else.

## Making the most of PostHog
See [PostHog Docs](https://posthog.com/docs/) for in-depth walk-throughs on functionality.
Join our [Slack community](https://posthog.com/slack) if you need help, want to chat, or are thinking of a new feature. We're here to help - and to make PostHog even better.
## 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](https://posthog.com/features).
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.
