Key strengths and limitations of each service
PostHog
Engineering-led product teams and startups needing a self-hostable, privacy-first all-in-one analytics suite with cookieless tracking, session replay, and experimentation tools.
- All-in-one platform bundles cookieless analytics with session replay, feature flags, and A/B testing, replacing multiple tools like FullStory and LaunchDarkly.
- Generous free tier up to 1M events/month with usage-based pay-as-you-go pricing, scaling transparently without fixed costs.
- Open-source and self-hostable with EU cloud hosting, cookieless modes (Always/On Reject), and HIPAA-ready compliance for full data control.
- Privacy-preserving server-side hashing and autocapture enable high-fidelity tracking without cookie banners or PII storage.
- Self-hosting is complex, resource-heavy (4x RAM of simpler tools), and lacks feature parity with cloud version.
- Overwhelming interface with extensive features that most teams won't fully utilize.
- No native ad platform integrations like Google Ads, unlike GA4.
