In a nutshell

PostHog is the best value proposition in product tooling. Analytics + session replay + feature flags + A/B testing in one open-source platform replaces $500+/month in separate tools. The individual products are good-not-best, but the combination at this price is unbeatable for startups.

What's great

  • All-in-one replaces 4-5 separate tools
  • Open source with free self-hosting
  • Cloud free tiers are genuinely generous

Watch out for

  • Individual analytics less powerful than dedicated Mixpanel/Amplitude
  • Session replay less polished than FullStory
  • Self-hosting requires infrastructure management

Best for

Startups wanting product analytics, session replay, and feature flags in one open-source platform.

Not ideal for

Enterprise teams needing the deepest analytics — Amplitude is more powerful for pure analytics.
