Fathom Lite - simple website analytics

Fathom Lite is a previous and open-source version of Fathom Analytics (a paid, hosted Google Analytics alternative). It was the very first version of our software, and has been downloaded millions of times!

While we are no longer adding features to this Lite version, we will be continuing to maintain it long-term and fix any bugs that come up.

Fathom Lite vs Fathom (hosted)

Today’s Fathom Analytics is a hosted product with simple pricing based on monthly pageviews. The same core capabilities are included on every plan: for example API access, up to 50 sites, custom events and ecommerce tracking, unlimited email reports and CSV exports, and forever data retention—with privacy-law compliance and no cookie banner required for analytics.

If you’d rather not run servers or maintenance yourself, try a 30-day free trial (that link applies a $10 credit on your first invoice). Browse all features or the live demo.
