I like how it has all the central features that any growing startup would use -- including feature flags, experiment and analytics.

The UI and UX of the website is top-notch and it's easy to navigate. The Session Replay feature was easy to implement in the iOS SDK. I also like the amount and depth of features that PostHog offers. We only tried Session Replay for now and it works great.

Self-hostable product analytics with autocapture and session replay, giving OORB full data control and deep behavioral insight. Most helpful / upsides: Unified event pipeline, fast feature flags, A/B testing, and session replay reduce instrumentation effort and speed experiments and debugging.
