Two Chromium extensions for Roblox. Run unlimited client instances side by side, and add real-time shaders to the picture.
Both load as unpacked extensions and run entirely in your browser.
Multi-account manager and mutex bypass
Isolated session cookies, no single-instance lock from RobloxPlayerBeta, and built-in playtime and revenue tracking.
Real-time post-processing pipeline
Screen-space reflections, HDR bloom, ambient occlusion and cinematic color grading, applied at presentation time.
Download a module and unzip it into a folder you won’t delete.
In Chrome, Brave or Edge, go to and turn on Developer mode in the top-right corner.
Click Load unpacked, pick the extracted folder, and launch as many Roblox accounts as you need.
MultiRoblox runs inside the Chromium Manifest V3 sandbox. It isolates cookie jars and manages launch tokens before the URI scheme fires. It does no memory injection or DLL hooking into RobloxPlayerBeta.exe, so it doesn’t trigger Hyperion anti-tamper heuristics.
The pipeline hooks the browser’s WebGL / WebGPU compositor. Lightweight GLSL passes handle bloom, ambient occlusion and color grading at presentation time, so no executable or asset on disk is changed.
Unpacked installs keep the full source on your machine so you can read it, skip Chrome Web Store restrictions, and avoid forced background updates.
Each client uses roughly 850 MB to 1.4 GB of RAM. For 5 instances, plan on at least 16 GB of memory and a DirectX 11/12 GPU like a GTX 1660 or better to hold 60 FPS per window.
