GA4 vs Plausible vs Fathom
Privacy first analytics has matured. Here is when GA4 still wins and when Plausible or Fathom is the better call.
By FrameCraft · Checked October 2026 · 3 options compared
Short answer
GA4 is free and deeply integrated with Google Ads, but it's complex and, in the UK and EU, needs cookie consent. Plausible and Fathom are simple, privacy-first paid tools that work without cookies. If you don't buy ads through Google, a privacy-first tool often gives clearer data with less effort.

What usually decides it
Consent and data completeness
Under UK and EU rules, GA4's cookies need opt-in consent, and many visitors decline, so reports undercount. Cookie-free tools can usually run without a banner and record more complete traffic. Check current ICO guidance for your situation, as UK rules on analytics cookies have been changing.
Advertising
If you buy Google Ads, GA4's integration is hard to replace. Some teams run GA4 for ads behind consent and a privacy-first tool for everyday reporting.
Who reads the reports
Plausible and Fathom fit on one screen and anyone can read them. GA4 rewards a specialist. Choose the tool your team will actually open every week.
