Fathom starts fresh. Nook builds on what you have.
Fathom replaces GA4 with its own tracking script. Your GA4 history and Search Console data stay behind. Nook gives you a clean dashboard built on the data you already collect. No starting over.
The key difference
Fathom replaces Google Analytics.
Nook sits on top of it.
Feature comparison
Why people choose Nook over switching to Fathom
Years of historical data, already collected
Your GA4 account has months or years of traffic data. Switching to Fathom means starting fresh or doing a limited import. Nook keeps you connected to all of it and lets you build on what you have.
Search Console integration matters
If you care about which search queries bring visitors to your site, GA4 plus Search Console is hard to beat. Fathom does not integrate with GSC. Nook puts search data front and center on every page report.
No new tracking script to manage
Nook reads from APIs. There is no additional JavaScript on your site, no DNS changes, no migration checklist. If GA4 is already running, Nook works immediately.
When Fathom is the better choice
We believe in being honest about where each tool fits best.
Privacy is non-negotiable
If you need cookie-free analytics with EU data isolation and full GDPR compliance without banners, Fathom is purpose-built for that.
You want to leave Google entirely
If your goal is to stop using Google products for analytics, Fathom gives you full independence. Nook requires a GA4 account.
Lightweight custom events
Fathom offers simple custom event tracking without the complexity of GA4 events. If you need basic goals without GA4's event model, Fathom is cleaner.
Real-time visitor counts
Fathom shows real-time visitor data instantly. Nook works with GA4's API, which has inherent processing delays.
Frequently asked questions
Fathom replaces Google Analytics entirely. It uses its own lightweight tracking script and stores data independently. Nook does the opposite: it connects to your existing GA4 and Search Console data and gives you a simpler way to view it. If you want to leave Google Analytics completely, choose Fathom. If you want to keep GA4 but hate using it, choose Nook.
Yes. Some teams run Fathom for real-time, privacy-friendly visitor counts and use Nook to access the deeper GA4 data they already collect: search queries, conversion paths, and historical trends. The two tools serve different purposes and do not conflict.
Nook reads from GA4, which uses cookies and collects data under Google's privacy terms. If cookie-free analytics with EU data isolation is your top priority, Fathom is purpose-built for that. Nook's advantage is that it works with data you already have without adding another tracking script.
Fathom supports importing from Google Analytics, but the import is limited and you lose GA4-specific dimensions like search queries, custom events, and attribution data. Nook preserves your connection to all of it and adds features on top.
Nook starts at $29/mo for up to 5 properties. Fathom starts at $14/mo for up to 100,000 pageviews. For low-traffic single sites, Fathom is cheaper. For multi-property portfolios, Nook's flat pricing is more predictable since it does not scale with pageviews.
