Roblox launcher for Windows

Your Roblox. Your launcher.

Defblox puts the games people are playing right now, a server picker, community chat and game invites into one clean black and white launcher.

We only use your email to tell you when Defblox opens.

Safe by design

Your account stays yours.

No password, ever

Defblox never asks for your Roblox password. You prove an account is yours by pasting a one-time code into your own profile.

Nothing is modified

No cheats, no injected code, no changed game files. Games open in the official Roblox app exactly as Roblox ships it.
