The open source product analytics suite for developers
Open-source product analytics suite with feature flags, session replay, and experiments.
Session replay, feature flags, A/B testing, and product analytics all in one tool — replacing four paid services with one
The generous free tier of 1 million events per month means most early-stage apps never need to pay anything
Self-hostable open source version gives you full data ownership which is essential for HIPAA or strict GDPR requirements
The SQL-based querying for custom analysis is more powerful than most analytics tools' point-and-click interfaces
Feature flags integrate directly with analytics, so you can measure the impact of every flag rollout without separate tooling
The UI can feel overwhelming — feature flags, insights, recordings, experiments, and surveys in one dashboard requires time to learn
Self-hosting is possible but requires significant DevOps knowledge and the managed updates are your responsibility
Session replay storage costs can add up fast if you have high traffic and keep recordings for a long time
