Why MultiRoblox

Built for many accounts, zero fuss

A single portable app holds Roblox’s single-instance lock so every extra window stays open.

One button

Press Launch Instance once per Roblox window. Every press opens another client.

Live status

See every running instance with its uptime and stop them all with one click.

Safe & simple

No files patched, no admin rights. Just a clean lock while MultiRoblox is open.
