The short answer
Editorial assessmentGoogle Analytics 4 compared with Fathom Analytics
Fathom is the pay-to-escape-GA4 product: a simple dashboard, no cookies, no banner, unlimited sites on every plan, and a GA import so history survives. GA4 wins only on price and ad integration. Choose Fathom if analytics is a reporting need; choose GA4 if analytics is an advertising input.
Choose Fathom Analytics if
Agencies, portfolio operators, and marketing teams with many sites who want dead-simple, consent-banner-free traffic and conversion reporting at a flat monthly price, with data retention that never expires.
Choose Google Analytics 4 if
Any business that runs Google Ads and needs conversion import, audience remarketing, and data-driven attribution inside Google's own ecosystem, plus larger sites that want a free raw event export into BigQuery and have someone able to write the SQL.

Strengths and limitations
Fathom Analytics
Strengths
- Every plan includes at least 50 sites and the full feature set, unmatched economics for agencies and multi-site operators.
- Forever data retention as a standard feature; analytics history survives as long as the subscription does.
- Real-time, genuinely simple one-page dashboard that non-analysts read without training.
- Cookie-free, personal-data-free architecture with EU Isolation, removing consent banners for analytics and easing GDPR/CCPA/ePrivacy/PECR review.
Limitations
- No funnels, user journeys, or any multi-step conversion analysis; measurement depth stops at events and UTM breakdowns, less than Plausible's Business plan offers.
- Closed source: unlike Plausible or PostHog, the privacy claims cannot be verified by reading the code.
- No user-level or account-level analytics of any kind, so product analytics and B2B attribution are out of scope by design.
- No free plan and a short 7-day trial, with published static pricing covering only part of the tier ladder (higher volumes are calculator-only).
Google Analytics 4
Strengths
- Free at unlimited traffic volume, which no privacy-first competitor can match once a site passes a few hundred thousand pageviews a month.
- The only analytics tool that can import conversions into Google Ads for bidding and export behavioural audiences for remarketing, which is decisive if paid search is a real channel.
- Data-driven attribution across Google and non-Google channels, plus behavioural and conversion modelling that partially recovers consent-declined traffic.
- Free raw event export to BigQuery gives genuinely unlimited retention and unsampled analysis for teams with SQL skills.
Limitations
- The interface is genuinely hostile to non-specialists; simple questions require Explore, and Explore requires understanding scope, cardinality, and dimension compatibility.
- Requires a cookie consent banner in the EU and UK, and the traffic that declines disappears into modelled estimates rather than being measured.
- Standard properties delete event-level data after 14 months, so year-over-year analysis in Explore breaks unless you run a BigQuery pipeline.
- Sampling, thresholding, and the (other) row on high-cardinality dimensions mean numbers are directional; GA4 will not reconcile line by line with your order database.
Pricing compared
Fathom Analytics
Flat monthly subscription tiered by monthly pageview volume; all features on every plan, at least 50 sites included, extra sites in packs of 50.
- Up to 100k pageviews$15
- Up to 500k pageviews$45
- Higher volumes (2M, 10M, 25M+ pageviews)Scales by calculator
Fathom's value case is strongest per site rather than per pageview: $15/month for 50 sites with every feature and permanent retention is the cheapest credible analytics setup an agency or portfolio operator can buy, and the everything-included model avoids Plausible-style feature gating. For a single high-traffic site the math is less special ($45/month at 500k pageviews is more than Plausible's equivalent band), and the absence of funnels or journey analysis means you are paying for simplicity, longevity, and site count, not analytical depth.
Google Analytics 4
Free at any traffic volume for the standard product, with usage limits rather than price tiers; the enterprise tier (Analytics 360) is quote-only and sold through Google Cloud sales.
- Google Analytics 4 (standard)$0
- Google Analytics 360Custom
Free is an unbeatable price for what GA4 does at the ad-integration layer, and no competitor at any price can import conversions into Google Ads or run Google's data-driven attribution. Judged purely as a dashboard, though, GA4 is expensive in the currency that actually constrains a small business, which is attention: the interface, the consent banner, the 14-month retention ceiling, and the sampling all cost hours or accuracy that a $19 tool would have given back. The rational allocation for most small businesses is to keep GA4 installed for the Google Ads link and pay a small amount for something readable to look at daily.
Editorial verdict on each
Fathom Analytics
Fathom is the pragmatic pick in privacy-first analytics: less ideological than Plausible (closed source, hosted where it is fastest, EU Isolation handling the compliance edge) but structurally more generous, with 50 sites, every feature, and permanent data retention on the cheapest plan. For agencies and anyone running many properties it is the best per-site deal in the category, and the product's refusal to grow past one page is exactly why its users keep it. The boundary is firm, though: no funnels, no journeys, no user or account analytics, so treat it as the traffic-and-conversions layer and pair it with deeper tools when the questions get harder.

GA4 is not a good product and it is still the right default for most small businesses, which is an uncomfortable thing to write. It is free at any volume, it is the only tool that can push conversions and audiences into Google Ads, and its data-driven attribution has no free equivalent. Against that: a hostile interface, a mandatory consent banner in Europe, a 14-month retention ceiling, sampling, and an attribution model list that got shorter rather than longer. Keep it if you spend money on Google Ads, because nothing else closes that loop. If you do not, install Plausible, Fathom, Simple Analytics, Pirsch, or Umami instead and enjoy getting your afternoons back.
