Fathom Analytics vs Hotjar in 2026: Cookieless quantitative reporting vs free-tier heatmaps and session replay
Fathom tells you how much traffic hit which pages without a consent banner. Hotjar shows you what visitors actually did on those pages, with a free tier that covers 200,000 monthly sessions.
Fathom Analytics
Hotjar- Fathom collects no cookies or personal data and requires no consent banner. Hotjar uses cookies and is GDPR/CCPA compliant through built-in consent controls, not through cookielessness.
- Hotjar's free tier covers 200,000 monthly sessions and includes heatmaps, session replay, funnels, and error monitoring. Fathom has no free tier, only a 7-day trial, starting at $15/month.
- Fathom has no heatmaps or session replay of any kind. Hotjar's core product is heatmaps and session replay, which is the primary reason teams add it.
- Hotjar includes an MCP connector, available even on the free plan, that lets ChatGPT, Claude, and Copilot query Contentsquare behavioral data in natural language. Fathom has no equivalent AI-assistant integration.
- Fathom retains all analytics data forever on every plan. Hotjar's session replay data is limited to 2 months even on the paid Growth tier.
- Fathom includes at least 50 sites on every plan for agency-style multi-client management. Hotjar's free plan is limited to 1 project, with Growth adding only 3.
- Hotjar is now part of Contentsquare, which also owns Heap, and its roadmap and pricing are increasingly shaped by that larger enterprise platform. Fathom remains 100 percent independently owned with no VC investors.
Fathom Analytics and Hotjar rarely get compared head-to-head because they measure different things, but plenty of teams end up choosing between them when picking a second analytics tool alongside GA4. Fathom is a cookieless, privacy-first web analytics platform starting at $15/month with no free tier, built to answer traffic questions cleanly and without a consent banner. Hotjar is a behavioral analytics platform built around heatmaps, session replay, and on-page surveys, with a genuinely usable free tier covering 200,000 monthly sessions. Since its 2024 absorption into Contentsquare, Hotjar has also picked up an MCP connector that lets you query behavioral data from Claude, ChatGPT, and other AI assistants. The two tools can coexist on the same site; the real question is which one you need first.
The tools at a glance
Fathom Analytics
Simple, GDPR-compliant web analytics with cookieless tracking, forever data retention, and no consent banners
Fathom Analytics is used on over a million websites and built around one idea: analytics should answer basic traffic questions without collecting cookies or personal data. A single script tag reports on visitor counts, top pages, referrers, countries, devices, and manually defined conversion events. Because nothing is stored on the visitor's device, no GDPR, CCPA, or PECR consent banner is required, which recovers the 30 to 50 percent of European traffic that consent-banner rejection typically loses.
Every plan includes the full feature set, API access, ecommerce tracking, and at least 50 sites, priced from $15/month with no tiered feature-gating. Data retention is forever on every plan, a deliberate contrast to tools that impose rolling data windows. The company is independently owned and bootstrapped, with no venture capital shaping the roadmap toward advertising or data monetization.
What Fathom does not attempt is qualitative behavioral analysis. There are no heatmaps, no session replay, and no way to watch what a specific visitor did on a page. If your question is "how many visitors and from where," Fathom answers it cleanly. If your question is "why did visitors abandon this specific form," it does not.

Hotjar
Heatmaps, session replay, and user feedback tools that show you what happens on your site and why
Hotjar is a behavioral analytics platform used on over 1.3 million websites, built around heatmaps, session recordings, and on-page surveys rather than page-view counting. The free tier covers 200,000 monthly sessions and includes replays, heatmaps, funnels, error monitoring, and 100 survey responses a month, which is enough for most small-to-mid-size sites to run without paying anything.
Since being fully absorbed into Contentsquare in 2024 (alongside Heap), Hotjar has gained zone-based heatmaps, journey analysis, impact quantification, and the Sense AI assistant on Growth and above, plus an MCP connector, available even on the free plan, that lets you query Contentsquare data in natural language from Claude, ChatGPT, or Copilot. The trade-off is that pricing now lives on the Contentsquare pricing page rather than hotjar.com, and the roadmap is being pulled toward a larger enterprise platform.
Where Hotjar is thinner is longitudinal data and product-analytics depth. Session replay recordings are capped at 2 months of retention even on paid Growth plans, and funnel analysis is page-level rather than event-level, which is simpler to set up but less granular than a dedicated product analytics tool.

Which should you choose?
HotjarFathom AnalyticsHotjarFathom AnalyticsHotjarFathom AnalyticsFathom and Hotjar are not really substitutes for each other; a meaningful number of sites run both at once, using Fathom for the traffic numbers and Hotjar for the qualitative "why." The decision point is really about what you are missing right now. If you already have a traffic dashboard and want to see actual user sessions, Hotjar's free tier gets you there without a procurement conversation. If you are tired of consent-banner data loss and want a clean, forever-retained record of your traffic, Fathom is the more focused tool.
Bottom line
Start with Hotjar's free tier if you need heatmaps and session replay today and 200,000 monthly sessions covers your traffic; it costs nothing to try. Choose Fathom Analytics if consent-banner data loss and GDPR overhead are actively costing you visibility into your traffic, or if you are an agency that needs predictable multi-site billing. Plenty of teams eventually run both.
Frequently asked questions
Can Fathom Analytics show me heatmaps or session recordings like Hotjar?
No. Fathom has no heatmaps and no session replay in any form; it reports on visitor counts, referrers, and manually defined conversion events. Hotjar is the tool built specifically for heatmaps and session recordings.
Does Hotjar require a cookie consent banner the way GA4 does?
Yes, Hotjar uses cookie-based tracking and relies on built-in GDPR and CCPA compliance controls rather than cookielessness. Fathom Analytics is the cookieless alternative in this comparison and needs no consent banner at all.
Is Hotjar's free tier actually usable for a real business?
Yes, for small to medium sites under 200,000 monthly sessions. The free tier includes heatmaps, session replay, funnels, error monitoring, and basic surveys. The main limits are the single-project cap and the lack of zone-based heatmaps or journey analysis, both reserved for Growth.
Why doesn't Fathom offer a free tier like Hotjar does?
Fathom is bootstrapped and independently owned, and its pricing philosophy is every plan gets the full feature set at a transparent rate starting at $15/month, with only a 7-day trial to evaluate. Hotjar uses a freemium model built to get a large volume of sites onto the platform before upselling Growth.
Is Hotjar still independent or is it fully part of Contentsquare now?
Hotjar is fully part of Contentsquare as of 2024, which also owns Heap. The Hotjar brand and core tools still exist, but pricing now lives on the Contentsquare pricing page and the roadmap is increasingly shaped by that larger enterprise platform. Fathom, by contrast, remains 100 percent independently owned with no outside investors.
Which tool is better for agencies managing several client sites?
Fathom Analytics. Every plan includes 50-plus sites with add-on packs at $10/month, which keeps multi-client billing predictable. Hotjar's free plan is capped at 1 project and Growth only adds 2 more, which is thin for an agency managing a real client roster.
