Roblox Lag Switch

A simple and clean lag switch designed exclusively for Roblox.

Features

• Toggle Connection – Block and unblock Roblox traffic with a single keypress.
• Custom Hotkey – Set any key as your toggle using the built-in key capture button.
• Auto Timed Reconnect – Automatically unblocks after 9 seconds to prevent disconnection.
• Focus Only Mode – Only blocks the Roblox window you're currently focused on.
• Volume Control – Adjustable beep volume with deeper, less harsh tones.
• Modern UI – Clean frameless dark theme with rounded corners and no clutter.
• Auto-Apply Settings – Changes save instantly, no restart required.

Usage

1. Run the .exe as administrator.
2. Set your desired hotkey.
3. Press the hotkey while in Roblox to toggle your connection.
4. With auto timed reconnect enabled, traffic unblocks automatically at 9 seconds.

Requirements

• Windows 10/11
• May require administrator privileges (sometimes required for firewall rules)

Building from Source

pip install pyqt5 psutil pynput pywin32
python main.py

Notes

• The lag switch works by creating temporary Windows Firewall rules to block Roblox traffic.
• All firewall rules are automatically cleaned up when the application closes.
• If focus only mode is enabled, the hotkey will only work when a Roblox window is in the foreground.
