Open-Source & Self-Hosted Alternatives to Google Analytics (GA4)
The dominant web analytics tool, burdened by complex GA4 UI, ad trackers, and GDPR compliance risks.
Why Migrate Away from Google Analytics (GA4)?
GA4 forces EU/global privacy headaches (cookie banners, GDPR/ePrivacy liability), slows down your site with heavy JavaScript tags, and samples your data. Self-hosting lightweight analytics gives you 100% data ownership, bypasses ad-blockers cleanly via your own domain, requires zero cookie banners, and loads in < 2KB.
