What is Multi Roblox?

Multi Roblox is a free Chrome extension that lets you run multiple Roblox accounts from one toolbar panel. Search for "multi roblox" and you'll find players looking for exactly this — a way to keep mains and alts signed in, switch instantly, and launch parallel game windows without the logout loop.

MultiRBX is built for Multi Roblox use: traders with storage alts, developers testing with QA accounts, and anyone who runs more than one identity on the same PC.

Multi Roblox features

• Multi Roblox roster — every main and alt in one panel with live avatars.
• Parallel launch — run multiple Roblox clients on Windows, Mac, or Linux.
• Same-place join — selected accounts join the game on your current tab.
• Instant switch — change active account without signing out of Roblox.
