Migrating from Google Analytics: A Comparative Analysis of Umami, Plausible, and Fathom
Prompted by recent supply chain security concerns involving TanStack NPM packages, this article details the author's decision to replace Google Analytics (GA4) with privacy-focused alternatives across three side projects. The migration is driven by practical considerations rather than ideology, including reduced script weight, elimination of cookie consent banners, improved vendor trust, and the option for self-hosting. The author evaluates three specific contenders: Plausible, an open-source AGPL tool written in Elixir; Fathom, a commercial closed-source cloud service; and Umami, an open-source MIT platform built on Next.js. A two-week side-by-side test compares these tools on features such as open-source status, self-hosting capabilities, GDPR compliance, script size, and funnel tracking. The analysis highlights that while GA4 remains superior for advanced marketing features like remarketing, lightweight alternatives offer significant performance and privacy benefits. The article provides technical insights into the migration process, noting that replacing GA primarily involves swapping script tags. It serves as a practical guide for developers seeking to reduce third-party dependencies and enhance site performance through modern, privacy-centric analytics solutions.
