Roblox normally allows only one client per computer by holding two named
kernel objects (ROBLOX_singletonMutex and ROBLOX_singletonEvent).
MultiRoblox owns those objects itself while its window is open, so every
additional client you launch is allowed to stay alive. Nothing is patched or
modified on disk, and no administrator rights are needed.
MultiRoblox.exe — a single portable .exe. Download, run, press Launch Instance.
Prefer Start Menu shortcuts and auto-update? Run the installer from PowerShell:
powershell -NoProfile -ExecutionPolicy Bypass -Command "iwr -useb https://raw.githubusercontent.com/HyperlinksSpace/MultiRoblox/main/installer/Install-MultiRoblox.ps1 | iex"- Run MultiRoblox.exe.
- Press Launch Instance — once for every Roblox window you want open.
- Sign into a different Roblox account in each window.
- Keep MultiRoblox open while playing. Click Stop All to close every client.
- Windows 10 or 11.
- The Roblox player installed (from roblox.com).
./build.ps1 # produces dist/MultiRobloxController.exeUses the .NET Framework csc.exe that ships with Windows, so no extra SDK is
required.
Every push to main triggers .github/workflows/release.yml, which:
- Builds
MultiRobloxController.exe - Packages the installer scripts + zip
- Publishes a new GitHub Release (
v1.<run>.0) with those assets
The download site is served by GitHub Pages from the docs/ folder on main.
