Analytics
5 products in analytics, ranked by the votes people cast.
Measuring what people do, split by the question you are asking. Web analytics answers how many and from where. Plausible and Fathom both do this without cookies, which means no consent banner and a script small enough not to matter, at the cost of the deep segmentation a heavier tool offers. Product analytics answers what happened next: Mixpanel and Amplitude are built around events, funnels, cohorts and retention curves, and both require you to decide what to track before they can answer anything. PostHog puts product analytics, session replay, feature flags and experiments in one open-source stack you can self-host. The most common mistake in this category is instrumenting everything and then having no question, which produces a dashboard nobody opens twice.
