Setup

Three steps, then you are in

No separate launcher and no account system. It runs from the browser you already use for Roblox.

  1. 01

    Capture

    Sign in to an account once and save the session to your local panel with a label.

  2. 02

    Mark

    Tick the accounts you want to open — your main, alts, farm accounts, the whole roster or just a few.

  3. 03

    Launch

    Hit Start marked. Every selected account opens in its own window, already signed in.

Product

What it does

Many at once

Several Roblox windows, side by side

Open as many accounts as you need at the same time, each isolated in its own window. No more logging out and back in.

Live state

See what is open

The panel shows which accounts are open right now and which are idle, so you never lose track.

Skip the login loop

Captured sessions reopen instantly. No re-login between alts.

Open only what you need

Mark specific accounts and start just those — or hit Start all.

Stays on this PC

Sessions live in the browser extension. Nothing is uploaded with the account list.

Local

Everything stays on your machine

Accounts and sessions live in your browser’s local storage. There is no account to create on rbxuniversal.com.
