Kot referen\u010dna strojna platforma so obravnavane plo\u0161\u010de Raspberry Pi 4.

Leta 2010, po prevzemu podjetja Palm, je platforma pre\u0161la v roke Hewlett-Packard, ki je posku\u0161al to platformo uporabiti v svojih tiskalnikih, tabli\u010dnih ra\u010dunalnikih, prenosnikih in osebnih ra\u010dunalnikih. Leta 2012 je podjetje HP napovedalo prehod webOS v neodvisen odprt projekt in leta 2013 za\u010delo objavljati izvorne kode njegovih komponent. Leta 2013 je platformo od Hewlett-Packard kupilo podjetje LG in se zdaj uporablja na ve\u010d kot 70 milijonih televizorjev in potro\u0161ni\u0161kih naprav LG. Leta 2018 je bil ustanovljen projekt webOS Open Source Edition, preko katerega se je podjetje LG posku\u0161alo vrniti k odprtemu modelu razvoja, privabiti druge udele\u017eence in raz\u0161iriti spekter naprav, ki jih podpira webOS.        <\/p>\n<p>Sistemsko okolje webOS je oblikovano z uporabo orodij in osnovnih paketov OpenEmbedded, ter sistema za sestavljanje in niza metapodatek projekta Yocto. Klju\u010dni komponenti webOS so upravitelj sistema in aplikacij (SAM, System and Application Manager), ki je odgovoren za izvajanje aplikacij in storitev, ter Luna Surface Manager (LSM), ki oblikuje uporabni\u0161ki vmesnik. Komponente so napisane z uporabo okvirja Qt in brskalni\u0161kega motorja Chromium.          <\/p>\n<\/p>\n<p>Prikaz se vr\u0161i putem kompozitnog menad\u017eera koji koristi Wayland protokol. Za razvoj korisni\u010dkih aplikacija preporu\u010duje se kori\u0161\u0107enje web tehnologija (CSS, HTML5 i JavaScript) i Enact okvira zasnovanog na Reactu, ali je mogu\u0107e i stvaranje programa na C-u i C++-u s interfejsom zasnovanim na Qt-u. Korisni\u010dka shell i ugra\u0111ene grafi\u010dke aplikacije uglavnom su implementirane kao nativni programi napisani koriste\u0107i QML tehnologiju. Podrazumevano se nudi Home Launcher shell, optimizovan za upravljanje na dodirom i koji nudi koncept menjanja kartica (umesto prozora).      <\/p>\n<p>Za \u010duvanje podataka u strukturiranom obliku koriste\u0107i JSON format primenjuje se DB8 skladi\u0161te, koje koristi LevelDB bazu podataka kao backend. Za inicijalizaciju se koristi bootd zasnovan na systemd-u. Za obradu multimedijalnog sadr\u017eaja nude se pod-sistemi uMediaServer i Media Display Controller (MDC), dok se za zvuk <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/sl\/server\/dts-los-angeles\/\"   title=\"stre\u017enika\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"3741\">stre\u017enika<\/a> koristi PulseAudio. Za automatsko a\u017euriranje firmvera koristi se OSTree i atomska zamena particija (pravi se dve sistemske particije, od kojih je jedna aktivna, dok se druga koristi za kopiranje a\u017euriranja).
