Features Overview
PostHog is the Swiss Army knife of product analytics. It bundles product analytics, session recordings, feature flags, A/B testing, and user surveys in one platform. For engineering-led teams, this means one SDK, one data pipeline, and one bill instead of juggling Amplitude + Hotjar + LaunchDarkly + Optimizely. The self-hosted option gives you full data control.

Which do you use?
Who Should Choose What?
→ Choose PostHog if:
You're an engineering-led team that wants analytics, feature flags, session replay, and experimentation in one open-source platform. Best for startups and developer-centric companies that value consolidation.
→ Choose Amplitude if:
You're an enterprise product team needing advanced behavioral cohorts, cross-product analytics, and polished reporting for stakeholders. Best for non-technical product managers at larger companies.
→ Consider neither if:
You only need simple website traffic analytics (use Google Analytics or Plausible) or pure session recording (use Hotjar or FullStory). For basic marketing analytics, these are overkill.

Frequently Asked Questions
Editor's Take
We switched from Amplitude to PostHog six months ago and our analytics bill dropped 70%. The feature flags alone saved us a $400/mo LaunchDarkly subscription. But I'll be honest — our PM team misses Amplitude's cohort builder. If your PMs drive analytics decisions, Amplitude is still king. If your engineers do, PostHog is a no-brainer.
