Voidstrap

Voidstrap is an open source Roblox launcher for Linux. It installs and launches Roblox through Sober, bringing settings, mods, and everyday tools together in one app.

Use classic character sounds, choose a different cursor, adjust graphics settings, or customize the launcher. Save FastFlag profiles for different setups and switch between them without rebuilding your configuration each time.

Sober and launching: set up Sober, launch Roblox experiences, and manage your launch preferences.

Graphics and performance: adjust available options, edit FastFlags, and create, rename, or switch saved profiles.

Mods: manage custom cursors, character sounds, fonts, textures, and other visual replacements.

Appearance: choose themes, colors, gradients, and launcher styles to match your desktop.

Roblox tools: access account and server tools, view session information, and track your playtime.

Desktop integration: customize Discord Rich Presence and use shortcuts to open Roblox or Voidstrap settings.

Roblox runs through Sober on Linux. The effect of individual FastFlags and mods depends on the current Roblox and Sober versions.
