// EDITOR'S TAKE

PostHog is the obvious Amplitude replacement, with autocapture, funnels, cohorts and retention in one self-hostable product, plus session replay and feature flags that Amplitude bills separately. Countly is the stronger choice when mobile SDKs and crash data matter most, whereas Rybbit and Fathom Analytics are privacy-first traffic tools that will not answer behavioural questions about user journeys.
