Les exploitants de sites font face à la pression de suivre le comportement des utilisateurs tout en respectant des lois comme le RGPD. Les amendes pour non-conformité ont dépassé des milliards d'euros depuis 2018. Offen Fair Web Analytics y répond avec un outil où les utilisateurs optent volontairement, accèdent à leurs données et gardent le contrôle. Développé en Allemagne et arrivé à maturité à l'été 2024, il fournit des métriques essentielles sans collecter d'IP, d'user agents ni s'appuyer sur des tiers. Auto-hébergé via un binaire unique ou Docker, il utilise des cookies first-party et le chiffrement de bout en bout. Soutenu par l'initiative Next Generation Internet de la NLnet Foundation, Offen compte plus de 960 étoiles sur GitHub depuis 2019. Ce projet berlinois de Frederik Ring et Hendrik Niefeld priorise la souveraineté des données pour les utilisateurs européens.
Offen Fair Web Analytics
Open-source, self-hosted web analytics with opt-in consent, browser-side end-to-end encryption, and a shared Auditorium so visitors can see and control their own usage data.
This entry was drafted from publicly available information and still needs human review before treating it as final due-diligence guidance.
Key capabilities
Offen installs via a single binary or Docker image, requiring basic server resources. Operators embed a script to track pages across sites. No complex setup—configuration happens through environment variables. This keeps data on-premises, aiding compliance and reducing latency. Supports subdomains and team sharing for enterprises managing multiple properties.
Users enter the Auditorium with a first-party cookie to view their metrics: unique sessions, top pages visited. Explanations clarify each stat's meaning and privacy impact. Opt-out or data deletion is instant. Operators see aggregates like real-time page views, unique users, without personal identifiers. End-to-end encryption prevents server access to raw data.
Track page views, unique users/sessions, top pages, weekly retention. Filter by URL patterns, location, referrer, UTM parameters, landing, or exit pages. Real-time updates and visualizations help optimize content. No bloat—focuses on actionable insights without invasive profiling.
The consent banner adjusts for color, shape, and fonts. Displays in users' preferred language from six options. Developers extend via open-source contributions. Comprehensive docs cover monitoring, UTM tagging, and troubleshooting.
