Développé par Kagi, Orion Browser est un navigateur rapide et axé sur la confidentialité.
Il s'appuie sur le moteur WebKit d'Apple afin de garantir une sobriété énergétique maximale.
Sa force réside dans sa compatibilité native avec les extensions Chrome et Firefox.
Orion intègre un bloqueur de publicités et de traqueurs sans collecter aucune télémétrie.
Il consomme nettement moins de mémoire RAM et de batterie que ses rivaux sous Chromium.
Son interface fluide et épurée se personnalise facilement selon tes besoins quotidiens.
Les marque-pages et onglets sont synchronisés de manière chiffrée entre tes appareils.
Modèle éthique et gratuit, il offre une alternative moderne et respectueuse de ta vie privée.
Historiquement pensé pour l'écosystème Apple, il existe sur macOS, iOS et iPadOS.
Une version bêta pour Linux était disponible via un dépôt Flatpak et une version Windows devait arriver avant fin 2026, malheureusement le développeur abandonne ces plateformes mais promet d'ouvrir les sources pour qui veut reprendre le flambeau.
