Many teams use both: Fathom for compliant traffic data and Hotjar for targeted UX research on specific pages.
How to switch from Fathom Analytics to Hotjar
- 1Export your historical data from Fathom Analytics using the CSV export option available in each site's dashboard report view, since there's no single bulk export across all sites—download pageviews, referrer, and goal data for the date ranges you want to keep.
- 2Create a Hotjar account and add your site, then install the Hotjar tracking script via Google Tag Manager or directly in your site's header, keeping the Fathom script active in parallel during the transition so you don't lose traffic data mid-switch.
- 3Accept that Hotjar won't import your Fathom historical analytics—heatmaps and session recordings only start collecting data from the moment you install the script, so archive your exported Fathom CSVs separately for reference.
- 4Rebuild any automations tied to Fathom, such as email traffic reports, using Hotjar's equivalent (if available) or a separate tool, and set up a replacement for Fathom's uptime monitoring since Hotjar doesn't offer that feature.
- 5Configure heatmaps, recordings, and surveys on your key pages in Hotjar, and set up a cookie consent banner if you don't already have one, since Hotjar's tracking requires consent in most regions unlike Fathom.
- 6Once data is flowing correctly in Hotjar, invite your team members (checking Hotjar's per-plan seat limits versus Fathom's unlimited team access), remove the Fathom script from your site, and cancel your Fathom subscription.
Fathom Analytics vs Hotjar: common questions
How do I export my data from Fathom Analytics before switching?+
Fathom lets you export site data as CSV from the dashboard under each site's report view, covering pageviews, referrers, and goal completions for a chosen date range. There's no bulk account-wide export, so you'll need to pull reports site-by-site if you track multiple domains. Fathom also offers API access on paid plans if you want to script the export instead of downloading CSVs manually.
What do I lose moving from Fathom to Hotjar?+
You lose the 1KB lightweight script, cookieless GDPR-by-default tracking, and the uptime monitoring that comes bundled with Fathom. Hotjar requires a cookie consent banner in most regions and its script is roughly 50x heavier, which can affect page load times. You also lose the historical traffic trends view Fathom gives you, since Hotjar doesn't import past analytics history.
Is Hotjar's free plan enough for a small team?+
The free Basic plan caps you at 35 daily sessions for heatmaps and recordings, which is workable for a low-traffic site but too limited for anything with regular visitor volume. If you need to track more sessions or want longer data retention, you'll need to move to a paid plan starting around $32/month. For basic traffic counting alone, Fathom's paid tier is usually more cost-effective than scaling up Hotjar just for session caps.
Does Hotjar integrate with the same tools as Fathom?+
Hotjar integrates with more tools overall, including Google Analytics, Slack, HubSpot, and various CMS platforms, which Fathom doesn't offer natively. However, Fathom's email reports and uptime monitoring don't have a direct Hotjar equivalent, so you'll need separate tools (like UptimeRobot) to replace that functionality. Check your specific integration needs before assuming full feature parity.
How does the cost compare over a year between Fathom and Hotjar?+
Fathom's entry plan runs about $180/year ($15/month), while Hotjar's free plan costs nothing but caps you at 35 daily sessions. If you need Hotjar's paid Business plan for more sessions, you're looking at roughly $384/year at the $32/month starting rate, which is higher than Fathom's base tier. The actual cost depends on your traffic volume, since both platforms scale pricing with usage.
