Fathom Analytics
About the web analytics category
Web analytics pricing in 2026 has split into three distinct tiers by purpose. Privacy-first pageview analytics (Plausible $9/mo, Fathom $15/mo) handle most marketing needs at fixed costs. Product analytics (Mixpanel, PostHog) charge per event or MTU and scale with usage — free tiers cover 1M events/mo but paid plans can jump to thousands at scale. Traditional Matomo sits in the middle offering cookieless GA replacement. Google Analytics 4 remains 'free' but charges for BigQuery storage at scale and requires consent banners in EU. For most businesses the real question is: cookieless and legal in EU without consent banners (Plausible/Fathom/Matomo) vs free but complex (GA4) vs behavioral analytics (Mixpanel/PostHog).
How to choose between web analytics options
Start by classifying your need: marketing analytics (page views, traffic sources, conversions) vs product analytics (user behavior, funnels, retention). For marketing: Plausible at $9/mo or Fathom at $15/mo (both 100k pageviews) — privacy-first, no cookies, no banners. Matomo Cloud at €29/mo is the GDPR-hardened option. For product analytics: Mixpanel Free (1M events) is the best entry — events, funnels, cohorts, retention all included. PostHog Pay-as-You-Go is similar but bundles feature flags, session replay, and surveys. For self-hosted (data sovereignty): Matomo On-Premise is free forever. GA4 is free but practically requires cookie consent flows in EU — factor that engineering cost in.
