TrackWhy vs PostHog
A powerful product-analytics suite — but heavy and engineer-first.
PostHog is a genuinely impressive product-analytics platform. Funnels, cohorts, session replay, feature flags, experiments, a data warehouse — it is a deep toolkit built for product and engineering teams who want to instrument everything and slice it every way. If you have an engineer to own the implementation and you need experimentation and replay alongside analytics, PostHog is excellent.
That breadth is also the trade-off. PostHog is heavyweight and engineer-oriented: meaningful value usually means defining events, identifying users, and building insights, often with a developer driving. The tracking bundle is large, it leans on cookies and identification for its core flows, and the pricing spans multiple metered products that can get hard to predict. For a founder or marketer who just wants to understand their website, it can be a lot of tool.
TrackWhy is the lighter, privacy-first counterpoint for web analytics specifically. Cookieless and banner-free, a 1.7 KB script, drill-down on every card, funnels, retention and paths from one typed filter algebra, Stripe revenue attribution and grounded AI insights — readable on day one, with no instrumentation project and no engineer required.

Why teams switch

You still get genuine drill-down — search, sort, paginate every breakdown and click any row to filter the dashboard — without shipping a large bundle or learning a heavier query model.
PostHog’s core flows lean on cookies and identification. TrackWhy is cookieless and banner-free out of the box, so your web analytics stay GDPR-friendly with nothing to configure.
Native Stripe revenue attribution plus AI narration grounded in your real numbers come in one flat plan — no metered add-ons to forecast.
Switching is quick
