MultiRoblox: multiple Roblox instances on one PC

MultiRoblox (people also type Multi Roblox) is an unofficial Windows helper for multiple Roblox instances. It is for a second account you own, a local playtest, or two Player windows without a second computer.

What it is actually for

The desktop Player is built as a single-instance app. A second click usually focuses the window you already have. MultiRoblox is one way to start another Player process on the same Windows login.

Accounts you own

Keep a main and an alt signed in without logging out or borrowing a laptop. Setup is in the accounts guide.

Dev

Two real clients

Studio playtests are still first. When you need two live Players, a second window is faster than asking a friend. See developer notes.

No second OS

A virtual machine isolates Windows, but it is a poor way to render two 3D clients. Compare VM vs MultiRoblox.

What MultiRoblox is not

It is not an executor, not a Robux generator, and not Roblox Studio. It does not ask for your password. If a site named MultiRoblox promises free limiteds or a “bypass,” close it and read the safety page.

If you only need two windows, install Roblox from the Microsoft Store and from roblox.com. Those two packages often run together with no extra tool. MultiRoblox is for extra desktop Player windows beyond that pair, or when you want both sessions as Player. Details: Store + Player.

Before you install anything

Confirm you are on this site, not an ad clone. Roblox Player must already be installed. Two clients use two shares of RAM, GPU, and network — budget from the requirements page, not from the size of the helper.

Windows download

The Download button saves MultiRoblox.exe. Hash and SmartScreen notes are on the download page. Do not use Discord attachments or survey gates.
