How to run multiple Roblox accounts at once on PC

If you need two (or more) Roblox clients open at the same time — trading, alts, grinding — MultiRoblox is built for that on Windows PC via Chrome / Edge.

What you need

• Google Chrome, Microsoft Edge, Brave, or another Chromium browser
• Developer mode in chrome://extensions (or edge://extensions)
• The free MultiRoblox ZIP from this site

Steps

1. Download MultiRoblox.zip and extract it to a folder you will keep.
2. Open extensions page → enable Developer mode → Load unpacked → select the extracted folder.
3. Sign into each Roblox account in the browser (one profile / session flow as the extension instructs).
4. Add accounts to the MultiRoblox roster, open a game on roblox.com, then use Launch / Launch all.
5. Each account starts in its own Roblox window — that is how you run multiple Roblox accounts at once on one PC.

Tips

• Keep the extension folder in place; moving it breaks “Load unpacked” until you reload the path.
• Close stuck Roblox processes in Task Manager if a launch hangs.
• MultiRoblox is not affiliated with Roblox Corporation.
