Fathom Lite is the open-source, MIT-licensed first version of Fathom Analytics: simple, privacy-focused website analytics built with Go and Preact that you host yourself. It tracks thousands of websites from one install, showing page views, referrers, devices, and browsers on a real-time dashboard without the weight of Google Analytics. Its first version was downloaded millions of times, and the project now sits in maintenance mode with long-term bugfixes but no new features.[1]
Quick verdict
Site owners who want Google-free analytics on hardware they control will get the most from Fathom Lite: free, MIT-licensed, simple to run, and honest about what it measures. Its frozen feature set and cookie-based tracking are the price of that simplicity. Teams that need events, funnels, or managed reliability — or that simply will not operate a server — should budget hosted Fathom from $15 per month instead of stretching Lite past its maintenance-mode limits.[1][2][3]

Key features
Essential stats only Collects the essentials — page views, referrers, devices, browsers — on one dashboard, deliberately skipping the dimension sprawl that makes GA4 feel like cockpit training.[1]
Real-time dashboard Stats stream in real time, so a launch post or newsletter send shows its traffic shape within seconds rather than after a processing delay.[1]
Spam and bot blocking Filters spam and bot traffic out of the numbers, keeping small-site stats readable without manual exclusion rules.[1]
Thousands of sites per install One install can track thousands of websites, so freelancers and small networks consolidate client analytics on a single server they control.[1]
Self-hosted data ownership Runs on your own server, so visitor data never leaves infrastructure you control — the core of its privacy proposition.[1]
Docker deployment Ships as an official usefathom/fathom Docker image driven by a config file, alongside the build-it-yourself Go and npm path.[1]
Minute-scale onboarding Create the admin with `fathom user add`, log in on port 8080, register a site ID, and paste the tracking snippet — no pipeline or schema design stands between install and first pageview.[1]
Lockdown-friendly snippet Documents the exact Content Security Policy directives its tracker needs, so sites with strict CSP headers can allow it without opening broad script permissions.[1]
Who will love it
Privacy-conscious owners wanting a GA alternative without a monthly fee: Lite removes Google from the loop at the cost of running one small service.[1][2]
Self-hosters who insist visitor data stays on their own hardware: the single-binary-or-container footprint is modest next to full BI stacks.[1]
Small and simple sites content with essential stats: blogs, portfolios, and docs sites that need trends and referrers rather than funnels and cohorts.[1]
Who should avoid it
Teams needing a moving product: maintenance mode means bugs get fixed but the Lite UI, cookie-based tracking, and feature list are frozen where they stand.[1]
Operators needing events, UTMs, an API, EU data isolation, custom domains, GA import, email reports, CSV export, or shared dashboards: every one of these is hosted-only, and Lite will not gain them.[1]
Teams wanting managed reliability on a budget: a single typical install with community support means you own scaling, backups, and incident response yourself.[1]
Alternatives and compatibility
Reviewers of Fathom's hosted successor consistently praise how it disappears into the background: easy setup, a clean dashboard, and privacy-respecting tracking that needs no cookie banner on the hosted tier.[1]
The recurring counterpoint is depth: reviewers wanting richer analysis hit Lite's ceiling even sooner, since Lite freezes an older, smaller feature set than the hosted product they reviewed.[1][2]

Questions worth asking
What is the best Fathom Lite alternative for non-technical users?
Is Fathom Lite really no-code?
Half yes. Day-to-day use is a simple dashboard plus a paste-in tracking snippet per site, but getting there requires building or pulling the binary or Docker image, writing a config file, creating the admin user, and operating the server yourself. It is no-code to use, not no-ops to run.[1]
How much does Fathom Lite cost per month?
Lite itself costs nothing per month: it is MIT-licensed and self-hosted, so you pay only for whatever server it runs on. If you would rather not operate a server, hosted Fathom starts at $15 per month for up to 100,000 monthly pageviews, verified October 9, 2026. Budget the hosted plan when you need events, EU data isolation, or team features Lite does not have.[1][2]
Can you self-host Fathom Lite?
Yes. Ship the Go binary or the official usefathom/fathom Docker image with a config file, create an admin user with `fathom user add`, and open port 8080. Documented extras include Content Security Policy directives for locked-down sites. You own scaling, backups, and updates; maintenance-mode Lite gets bugfixes, not new features.[1]
