Overview:
Fathom Lite is a self-hosted, open-source website analytics tool. It was the initial version of Fathom Analytics, a paid hosted service positioned as an alternative to Google Analytics. Fathom Lite allows users to run their own analytics server and track website visitors without relying on a third-party service. It is suitable for developers and self-hosters who prefer to manage their own infrastructure for analytics.
Core Features:
Self-hosted deployment: Users run and maintain their own analytics server via Docker.
Tracking snippet: Provides a JavaScript snippet to embed on websites to start collecting visitor data.
Content Security Policy (CSP) support: Allows configuration of CSP directives for the tracking script.
Use Cases:
Developers who want to self-host website analytics on their own server infrastructure.
Site owners needing a simple, MIT-licensed analytics tool without managing a paid subscription.
Users with a single website install: The typical setup involves tracking one site per instance.
Why It Matters:
As an open-source release of a commercial analytics product, Fathom Lite offers a functional, self-hosted alternative for those who can manage their own server. Its MIT license permits broad use and modification. However, it lacks many features of the hosted version, such as API access, custom event tracking, email reports, and cookie-free tracking. The project is maintained for bug fixes but receives no new feature development.
