Compare verdict

What the compare page says

PostHog wins for product-led teams needing funnels, flags, and replay. GA4 wins when you only need free web traffic reporting.

Switching considerations

A startup compare decision should not stop at features. Switching costs usually hide in contact cleanup, event taxonomy migration, pipeline habits, internal training, and reporting continuity. If the team cannot explain the transition plan, the cheaper-looking option can still become the more expensive operating choice.

Pricing verification note

Free plans, AI add-ons, seat minimums, and usage caps change frequently. Treat this compare page as a decision lens, then confirm the exact numbers on the vendor pricing pages before you commit procurement time.
