Feature Comparison

Pros & Cons

Fathom Analytics

Pros

  • No cookies required, eliminating the need for consent banners on your site
  • Single-page dashboard shows all metrics at a glance with real-time data processing
  • Full GDPR, CCPA, ePrivacy, and PECR compliance verified by legal experts
  • Automatic bot and spam filtering for more accurate human visitor data
  • Forever data retention—no data expiration regardless of how long you're a customer
  • Single line of code setup that works with any website, CMS, or framework

Cons

  • No free tier—starts at $15/month, which may deter hobby sites or personal blogs
  • Deliberately simplified dashboard lacks the granular reporting and segmentation available in Google Analytics
  • No user-level tracking or cohort analysis, which limits behavioral analysis capabilities
  • Pricing based on pageviews can become expensive for high-traffic sites

Keen

Pros

  • Complete managed data pipeline from ingestion to visualization eliminates infrastructure overhead
  • Built-in data enrichment automatically adds geolocation, URL parsing, and other context to events
  • White-labeled visualization library allows embedding branded dashboards directly in customer-facing apps
  • Flexible JSON event schema with no rigid structure requirements

Cons

  • No free tier available — the entry price of $149/mo may be steep for small projects or prototyping
  • Overage charges can add up quickly ($1 per 5,000 events, $5 per 100 queries beyond plan limits)
  • 2-year data retention cap on Team and Business plans requires Custom tier for longer storage

Our Verdict

Both Fathom Analytics and Keen are excellent choices with similar feature sets. Your decision should depend on your specific needs, pricing, and whether you need self-hosting capabilities.
