Open-source product analytics with session replay, feature flags and A/B testing in one platform.
Why we recommend it
PostHog replaces three or four separate tools, and being self-hostable it sidesteps a lot of data-privacy friction.
Strengths
- Analytics, replay and flags in one tool
- Open source and self-hostable
- Very generous free tier
Drawbacks
- Broad surface area takes time to learn
- Self-hosting needs real infrastructure
