Umami vs Fathom Analytics
Both are alternatives to Google Analytics. Here's how they stack up — verified facts, no spin.
Also searched as Fathom Analytics vs Umami — same comparison, one verdict.
Umami is open source (MIT) and Fathom Analytics is not (Proprietary) — so the real question is whether you want to own the web analytics stack or rent it.
Umami
Simple, fast, self-hostable web analytics.
Umami is an MIT-licensed, privacy-focused analytics app you host yourself, offering the essential metrics with a light footprint and a clean UI.
Fathom Analytics
Privacy-first analytics with no cookie banner — the easy hosted pick.
Fathom is a simple, privacy-first analytics service and the closest easy replacement for Google Analytics: one script, a clean dashboard, and no cookie-consent banner because it sets no cookies and collects no personal data (GDPR/CCPA compliant out of the box, with optional EU-isolation routing). It's a paid hosted service rather than open-source, so it's here as the honest “just make it work” pick alongside the self-hostable champions — you trade self-hosting for zero maintenance.

Which one fits you
The trade-offs above, turned into a decision. Find the line that describes your team.
Choose Umami
if you want the source and the option to fork it, and you would rather run it on your own hardware, and permissive MIT license.
Choose Fathom Analytics
if no cookie banner — sets no cookies, collects no personal data.
Neither, yet
if both carry a real cost you should weigh first — basic reporting by design, and proprietary and hosted — you don't own or self-host it. If either of those is a dealbreaker for your team, the shortlist is wrong rather than the choice.
What it takes to run these yourself
Real requirements and honest running costs, not the vendor quickstart.
Umami vs Fathom Analytics — common questions
Is Umami a better fit than Fathom Analytics for web analytics?
It depends on what you are optimising for, and the honest split is this: Umami scores 90 to Fathom Analytics's 40 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. Fathom Analytics earns its place on a different axis — no cookie banner — sets no cookies, collects no personal data. Neither is a wrong answer for every team; the table above is the actual comparison.
What happens if we want to switch later?
Neither of these is local-first by default, so plan the exit at the point you adopt rather than later. Export what matters on a schedule instead of trusting you can retrieve it on demand — that is the most common way a web analytics migration turns into a project instead of an afternoon.
Can I self-host Umami?
Umami can be self-hosted; Fathom Analytics cannot, so it stays on the vendor's infrastructure whatever you do.
Are Umami and Fathom Analytics both alternatives to Google Analytics?
Yes — both appear in our Google Analytics comparison, which is why they are worth putting side by side. People usually arrive here already having decided to move off Google Analytics and now choosing between the two replacements, which is a narrower and much easier question.
