Ho lokolloa ha sethala se bulehileng sa webOS Open Source Edition 2.14 se hatisitsoe, se ka sebelisoang lisebelisoa tse fapaneng tse nkehang habonolo, liboto le litsamaiso tsa infotainment ea koloi. Liboto tsa Raspberry Pi 4 li nkuoa e le sethala sa lisebelisoa tsa lisebelisoa.

Sethala sa webOS se qapiloe ke Palm ka 2008 mme se sebelisoa ho li-smartphones tsa Palm Pre le Pixie. Ka 2020, ka mor'a ho fumana Palm, sethala se ile sa fetela matsohong a Hewlett-Packard, ka mor'a moo HP e ile ea leka ho sebelisa sethaleng sena ho bahatisi ba eona, matlapa, lilaptop le li-PC. Ka 2012, HP e phatlalalitse ho fetisetsoa ha webOS morerong o ikemetseng oa mohloli o bulehileng 'me ka 2013 e qala ho bula khoutu ea mohloli oa likarolo tsa eona. Sethala se ile sa fumanwa ho Hewlett-Packard ke LG ka 2013 mme jwale se se se sebediswa ho feta dimilione tse 70 tsa LG TV le disebediswa tsa bareki. Ka 2018, morero oa webOS Open Source Edition o ile oa thehoa, oo LG e ileng ea leka ho khutlela mokhoeng o bulehileng oa nts'etsopele, ho hohela barupeluoa ba bang le ho atolosa mefuta e mengata ea lisebelisoa tse tšehetsoeng ho webOS.
Tikoloho ea tsamaiso ea webOS e thehoa ka ho sebelisa OpenEmbedded toolkit le liphutheloana tsa motheo, hammoho le tsamaiso ea kaho le metadata e behiloeng ho tloha morero oa Yocto. Likarolo tse ka sehloohong tsa webOS ke tsamaiso le mookameli oa kopo (SAM, Motsamaisi oa Tsamaiso le Kopo), e ikarabellang bakeng sa ho tsamaisa lits'ebetso le lits'ebeletso, le Luna Surface Manager (LSM), e leng sebopeho sa mosebedisi. Likarolo li ngotsoe ho sebelisoa moralo oa Qt le enjene ea sebatli sa Chromium.
Ho fana ho etsoa ka mookameli oa sehlopha ea sebelisang protocol ea Wayland.
