L'environnement de bureau de base est construit sur Xfce (il est \u00e9galement possible d'installer la combinaison GNUstep + Window Maker + GWorkspace). Contrairement \u00e0 d'autres distributions de bureau de FreeBSD, MidnightBSD a \u00e9t\u00e9 initialement d\u00e9velopp\u00e9 comme un fork de FreeBSD 6.1-beta, qui a \u00e9t\u00e9 synchronis\u00e9 en 2011 avec la base de code de FreeBSD 7 et a ensuite int\u00e9gr\u00e9 de nombreuses fonctionnalit\u00e9s des branches FreeBSD 9-13. Pour la gestion des paquets, MidnightBSD utilise le syst\u00e8me mport, qui utilise une base de donn\u00e9es SQLite pour stocker les index et les m\u00e9tadonn\u00e9es, ou l'outil Ravenports.
