PostHog

Open-source product analytics with feature flags, session replay, and A/B testing in one platform. Best for engineering teams that want product analytics plus experimentation tooling. Not a direct GA4 replacement for marketing attribution. Free tier: 1 million events per month.

Umami

Minimal open-source web analytics. Basic feature set, essentially a privacy-first pageview counter. Best for developers and teams that want self-hosted simplicity. Free self-hosted.

How to Choose by Primary Use Case
