fathom

Fathom Lite is the original open-source release of Fathom Analytics, described in its README as a simple, privacy-focused website analytics tool and a Google Analytics alternative. The project is MIT licensed, and the README states that the Lite version no longer receives new features but will continue to be maintained long-term, with bugs fixed as they come up. What it does - Self-hosted website analytics: you run the server and updates yourself. - A tracking snippet, copied from the dashboard, is placed on the websites you want to measure. - A dashboard shows the collected analytics data; the frontend is built with Preact. - The backend and command-line tooling are written in Go. Installation and running - Production guidance is provided in the repository documentation (docs/Installation instructions.md). - Development flow: install Go and NPM, clone the repository, compile with make build, optionally set custom configuration values (docs/Configuration.md), register an account with ./fathom user add --email=... --password=..., then start the webserver with ./fathom server and open http://localhost:8080. - Docker: build with docker build -t fathom . and run with docker run -d -p 8080:8080 fathom, or run the published image usefathom/fathom:latest. Tracking and CSP If a tracked site uses a Content Security Policy, the README notes that the directives script-src and img-src must include the URL of the Fathom instance, replacing yourfathom.com with your own address. Comparison with the hosted product The README contrasts the Lite edition with the paid hosted Fathom Analytics. According to that comparison table, Lite is self-hosted and uses cookies, has an older dashboard, provides no API, and lacks custom events, ecommerce and UTM tracking, EU isolation and custom-domain script hosting, GA import, email reports, CSV export and shared dashboards. It is typically a single install with community support only, and CDN, scaling and backups are your responsibility. The hosted version lists managed hosting with pricing based on monthly pageviews, cookie-free tracking, a full real-time dashboard, API access on all plans, events and revenue tracking, EU isolation, GA import, unlimited reports and exports, up to 50 sites, support on every plan, and ongoing feature development. The repository also notes that Fathom and the Fathom logo are trademarks of Fathom Analytics.
