Best Open-Source Analytics in 2026

Q: What is the best open-source analytics?

Our top pick is Plausible: Privacy-first, cookieless, 1KB script. Self-host or use $9/mo cloud. Best for marketing sites.

Google Analytics is invasive (cookies, GDPR pain) and slow. The best open-source analytics in 2026 are privacy-first, GDPR-safe by default, faster scripts, and (often) more useful insights than GA4.
