Unleash the full potential of your Roblox experience with seamless multi-instance management, advanced FPS optimization, and next-generation script integration.
Engineered for power users, modders, and competitive gamers who demand more from their platform.
MultipleRobloxInstances is a robust, open-source utility that redefines how you interact with Roblox on Windows. Whether you're running multiple game instances simultaneously, boosting your frames per second, or diving into advanced script execution, this tool provides a unified, modular, and extensible framework. Inspired by projects like Bloxstrap, RBXFPSUnlocker, and script hubs, this repository consolidates the best of Roblox modding into a single, maintainable codebase.
Why this exists:
Roblox's native architecture restricts users to a single game instance, locks frame rates, and offers limited modding capabilities. This project breaks those barriers—ethically and legally—by providing a transparent, community-driven solution that respects Roblox's Terms of Service while empowering advanced workflows.

Create a profiles.json file in the application directory to define custom instance profiles:
{
"profiles": [
{
"name": "Competitive Gaming",
"multi_instance_count": 3,
"fps_limit": 240,
"bloxstrap_path": "C:\\Bloxstrap",
"script_enabled": true,
"script_file": "scripts/aim_assist.lua",
"language": "en",
"api_keys": {
"openai": "your-openai-api-key-here",
"claude": "your-claude-api-key-here"
}
},
{
"name": "AFK Farming",
"multi_instance_count": 5,
"fps_limit": 60,
"bloxstrap_path": "C:\\Bloxstrap",
"script_enabled": false,
"language": "ja",
"api_keys": {}
}
]
}Launch the launcher with a specific profile directly via Command Prompt or PowerShell:
MRI_Launcher.exe --profile "Competitive Gaming" --headless --log-level verboseArguments:
--profile <name>: Load a predefined profile fromprofiles.json--headless: Run without the GUI (console-only mode)--log-level <verbose|info|error>: Control logging verbosity

Leverage generative AI for script development and optimization:
- Script Auto-Completion: While writing Lua scripts in the built-in editor, press
Ctrl+Spaceto invoke AI-powered suggestions. - Error Analysis: When a script fails, the tool can send the error to OpenAI or Claude for explanation and fixes.
- Optimization Suggestions: The AI can analyze your FPS unlocker configuration and recommend optimal settings based on your hardware.
Configuration: Set your API keys in the config.json file or via the UI under "Settings > AI Integration".
A curated collection of scripts for:
- Anti-Idle bypass (respecting server limits)
- Camera manipulation (FOV, rotation, clipping)
- Inventory management (auto-reorganization)
- UI enhancements (transparent overlays)
All scripts are sandboxed—they run in isolated environments and cannot access system files.
