PostHog is an all-in-one, open source platform for building better products

Specify events manually, or use autocapture to get started quickly
Analyze data with ready-made visualizations, or do it yourself with SQL
Only capture properties on the people you want to track, save money when you don't
Gather insights by capturing session replays, console logs, and network monitoring
Improve your product with A/B testing that automatically analyzes performance
Safely roll out features to select users or cohorts with feature flags
Send out fully customizable surveys to specific cohorts of users
Connect to external services and manage data flows with PostHog CDP

PostHog is available with hosting in the EU or US and is fully SOC 2 compliant. It's free to get started and comes with a generous monthly free tier:

1 million product analytics events
5k session replays
1 million feature flag requests
250 survey responses

We're constantly adding new features, with <a href="https://posthog.com/docs/web-analytics">web analytics</a> and <a href="https://posthog.com/docs/data-warehouse">data warehouse</a> now in beta!

Open-source vs paid

Get started for free

PostHog Cloud (Recommended)

The fastest and most reliable way to get started with PostHog is signing up for free to PostHog Cloud or PostHog Cloud EU. Your first 1 million events (and 5k replays) are free every month, after which you pay based on usage.

Open-source hobby deploy (Advanced)

You can deploy a hobby instance in one line on Linux with Docker (recommended 4GB memory):

 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/posthog/posthog/HEAD/bin/deploy-hobby)"

Open source deployments should scale to approximately 100k events per month, after which we recommend migrating to a PostHog Cloud instance. See our docs for more info and limitations. Please note that we do not provide customer support for open source deployments.

PostHog brings all the tools and data you need to build better products.

Analytics and optimization tools

Event-based analytics: Capture your product's usage automatically, or customize it to your needs
User and group tracking: Understand the people and groups behind the events and track properties about them when needed
Data visualizations: Create and share graphs, funnels, paths, retention, and dashboards
SQL access: Use SQL to get a deeper understanding of your users, breakdown information and create completely tailored visualizations
Session replays: Watch videos of your users' behavior, with fine-grained filters and privacy controls, as well as network monitoring and captured console logs
Heatmaps: See where users click and get a visual representation of their behaviour with the PostHog Toolbar
Feature flags: Test and manage the rollout of new features to specific users and groups, or deploy flags as kill-switches
A/B and multivariate experimentation: run simple or complex changes as experiments and get automatic significance calculations
Correlation analysis: Discover what events and properties correlate with success and failure
Surveys: Collect qualitative feedback from your users using fully customizable surveys

Data and infrastructure tools

Import and export your data: Import from and export to the services that matter to you with the PostHog CDP
Ready-made libraries: We’ve built libraries for JavaScript, Python, Ruby, Node, Go, Android, iOS, PHP, Flutter, React Native, Elixir, Nim, and an API for anything else
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 apps - such as BigQuery, Redshift, Snowflake, and S3

Submit a feature request or bug report

Philosophy

Our mission is to increase the number of successful products in the world. To do that, we build product and data tools that help you understand user behavior 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 gives you every tool you need to understand user behavior, develop and test improvements, and release changes to make your product more successful.

PostHog operates in public as much as possible. We detail how we work and our learning on building and running a fast-growing, product-focused startup in our handbook.

Open-source vs. paid

This repo is available under the MIT expat license, except for the ee directory (which has its license here) if applicable.

Need absolutely 💯% FOSS? Check out our posthog-foss repository, which is purged of all proprietary code and features.

To learn more, book a demo or see our pricing page.

We’re hiring!

Come help us make PostHog even better. We're growing fast and would love for you to join us.
