Can you play Roblox on Linux or a Steam Deck?
You can play Roblox on Linux, but only through an unofficial community route, because Roblox has no native Linux client. The tool most people use is Sober, a Flatpak on Flathub that runs Roblox on Linux and on the Steam Deck's desktop mode. It works well for a lot of players, but since it is not made by Roblox, treat it as best-effort rather than guaranteed.
Whichever way you get in, our browser tools work everywhere, including in a Linux browser. The same free extension behind Roblox on Mac installs in Chrome or Firefox on Linux and improves the roblox.com website the same way it does on any other system.
Why there's no official Roblox on Linux
Roblox ships native apps for Windows, macOS, Chromebook, mobile and consoles, but not for desktop Linux. It has not committed to one, and its anti-cheat setup has historically been the sticking point. So there is no download button on the Roblox site that gives you a Linux client. That gap is exactly why the community built its own way in.
Sober: the Flatpak community route
Sober is a community-maintained Flatpak that runs the Roblox client on Linux. You install it from Flathub the same way you would any other Flatpak, sign in with your normal account, and launch experiences from there. It is not an exploit and it does not change the game to cheat. Just keep in mind that when Roblox updates, an unofficial wrapper can lag behind for a day or two until the maintainers catch up.
Roblox on a Steam Deck
The Steam Deck runs SteamOS, which is Linux, so the same rules apply. Drop into desktop mode, open the Discover software store, install Sober from Flathub, and you can add it back to Game Mode as a non-Steam shortcut. Plenty of Deck owners play Roblox this way. It is the practical answer for handheld Linux, with the same unofficial caveat.
Where BetterBLOX fits on Linux
The BetterBLOX extension runs in your Linux browser and upgrades roblox.com with a dark theme, server region and ping info, and profile tools. On the desktop-app side, BetterStrap ships on Windows and macOS, but not Linux, and a native Linux bootstrapper is not something we can promise yet. For now, the extension is the part that works on Linux out of the box.
