PostHog gives you product analytics and session replay in one place, so you can see both what people did (events, funnels) and watch a real session to understand why they got stuck. It is open source and self-hostable, and the free tier (1 million events and 5,000 session recordings a month) covers most MVPs without a card. That mix of numbers plus watching real sessions is exactly what keeps you from over-instrumenting: you track a few events, then watch replays to fill in the story.

- One tool covers both quantitative events and qualitative session replay, so you learn the what and the why without stitching together two products.
- The free tier is generous enough for a real MVP, and self-hosting is an option if you want full control of your data.
- Start by tracking a handful of key actions (signup, activation, the core action), then use session recordings to understand the drop-offs instead of adding more and more events.
