Privacy-first, without stopping at pageviews
Umami and Fathom share the same philosophy: cookie-free, privacy-first analytics that don't need a consent banner. The difference is depth. Fathom deliberately stays a single simple dashboard — no funnels, cohorts, segments, session replay, or heatmaps. Umami keeps the simplicity but adds the tools you reach for when a number needs explaining: watch a session, build a funnel, compare cohorts.
Actively developed open source
Fathom's open-source version, Fathom Lite, has been feature-frozen for years — it receives only security fixes and lags far behind the paid product. Umami's MIT-licensed codebase is the product: the same software behind Umami Cloud, actively developed in the open with hundreds of contributors, and completely free to self-host.
Free to start
Fathom has no free plan — pricing starts at $15/month after a short trial. Umami Cloud has a free tier so you can start without a credit card, and self-hosting is free forever. When you outgrow the free tier, plans start at $20/month.
