Vulkan e akaretsa lipolanete tsohle tse fumanehang 'me e fana ka API e le' ngoe bakeng sa komporo, selefouno, le webo, e lumellang API e le 'ngoe e tloaelehileng hore e sebelisoe ho li-GPU tse ngata le lits'ebetso. Ka lebaka la meralo ea Vulkan ea meralo e mengata, e bolelang lisebelisoa tse sebetsang le GPU efe kapa efe, li-OEM li ka sebelisa lisebelisoa tse tloaelehileng tsa indasteri bakeng sa tlhahlobo ea khoutu, ho lokisa liphoso le ho hlahisa profil nakong ea nts'etsopele.

Ho laola lisebelisoa le li-skrini, Vulkan e fana ka sebopeho sa WSI (Window System Integration), se rarollang mathata a batlang a tšoana le a EGL ho OpenGL ES. Ts'ehetso ea WSI e fumaneha ka ntle ho lebokose la Wayland - lits'ebetso tsohle tse sebelisang Vulkan li ka sebetsa sebakeng sa li-server tsa Wayland tse sa fetoloang.
