Leading open-source product analytics platform with AI observability, directly relevant to data engineering and developer experience.
PostHog is an open-source platform that unifies product analytics, session replays, feature flags, experiments, error tracking, logs, surveys, data warehousing, and AI observability into a single self-driving product intelligence suite. It introduces a self-driving mode that converts product signals like errors and rage clicks into researched reports and pull requests, and offers an MCP connector for integration with AI coding agents like Claude Code and Cursor. The platform provides a generous free tier on its cloud offering (1M events/month) and supports self-hosting via a one-line Docker deploy, with SDKs spanning JavaScript, Python, React Native, and more.
