PostHog

PostHog is an open-source analytics platform that provides a comprehensive suite of product analytics tools. It allows teams to track user behavior, monitor web traffic, and analyze data through visualizations or SQL queries. The software is available as a managed cloud service with dedicated US and EU regions or as a self-hosted instance deployed via Docker on Linux for those requiring full control over their data infrastructure.

Users integrate the platform into their applications using a JavaScript web snippet, various SDKs, or a direct API. It supports a wide range of environments including frontend frameworks, mobile apps, and backend languages. The platform serves as a central hub for measuring activation, tracking retention, and capturing revenue data, helping teams make decisions based on actual user interactions rather than assumptions.

The project is maintained as a monorepo and offers a separate repository for those seeking a version entirely purged of proprietary code.
