[architecture] Should I self-host Matomo instead of using Google Analytics 4?

Self-host Matomo On-Premise when GDPR/data sovereignty, no data sampling, and consent-banner-free tracking are hard requirements. Stay with GA4 if your workflow depends on Google Ads attribution, BigQuery export, and a managed zero-ops stack. Budget for premium plugins if you need funnels, heatmaps, session recording, or form analytics.

Journey Context:
Matomo is the mature open-source GA alternative: PHP/MySQL, GPL-3.0, full raw-data access, and CNIL-approved GDPR compliance. The catch is the 'free core' model: advanced features like funnels, user flows, and heatmaps are paid premium plugins, and self-hosting means you manage MySQL, PHP, cron archiving, and scaling. Matomo's tracking script is also heavier than lightweight alternatives. GA4 is free, integrates tightly with Google marketing tools, and exports to BigQuery, but it samples data on the free tier and creates privacy/legal exposure in the EU. The decision usually hinges on whether you are optimizing for marketing attribution \(GA4\) or data ownership and compliance \(Matomo\).
