Basilisk est un navigateur internet "laboratoire", c'est-à-dire, que les développeurs le considère comme toujours en phase "bêta". Originellement crée par les développeurs de MoonChild Productions, éditeur du navigateur Pale Moon, il était destiné à tester certaines fonctions avant intégration à Pale Moon. Désormais, depuis août 2022, Basilisk vole de ses propres ailes grâce à une nouvelle équipe.
Toujours clone de Firefox et basé sur le moteur Goanna (fork de Gecko), cette nouvelle équipe continuera à développer le code (basé sur XUL) abandonné par l'équipe de Mozilla lors du basculement de Firefox 56 à 57 tout en le modernisant.
De ce fait, Basilisk est désormais un navigateur totalement indépendant et suit donc son propre rythme de mise à jour. Il est cependant disponible que sur Windows (à partir de Windows 7) et Linux. Une version compatible pour macOS ARM (M1/M2) est en préparation...
