FNF MOB is an online platform for playing Friday Night Funkin’ mods directly in a web browser on mobile devices, tablets, and computers. Its catalog features a range of community-made rhythm games, including mods such as VS Whitty, Indie Cross, VS Tricky, QT, and Silly Billy, alongside the original Friday Night Funkin’. Players can start without downloading large files and use PC keyboard controls or customizable mobile touch layouts, including hitbox, left-control, right-control, and custom options.

The platform says it rebuilds open-source mods to support browser play across Android, iPhone and iPad, Windows, Mac, and Linux. It works with mods originally made for engines such as Psych Engine, Kade Engine, and V-Slice, aiming to make PC-focused fan creations accessible on mobile while preserving their gameplay. FNF MOB also points visitors to an Android game for additional mods and a community gameplay video section where players can discover or share videos. The site presents itself as part of the Friday Night Funkin’ modding community, with new mods promised regularly.
