C00lgui V2

Gone are the days of the default grey box. C00lgui V2 ships with a Custom Theme Engine. Users can modify:

If you’ve been around the user interface customization scene for a while, you know the name. The original C00lgui was a staple for power users who wanted functionality over fluff. But let’s be honest: the UI was strictly utilitarian, a relic of a bygone era of clunky buttons and gray backgrounds.

Enter C00lgui V2.

I recently got my hands on the updated version, and it feels less like a patch update and more like a total reconstruction from the ground up. Here is why V2 is turning heads: C00lgui V2

One of the most interesting aspects is how V2 deliberately avoids modern UI conventions:

This suggests the developer understood not just automation, but operational security for the end user.

The first thing you notice is the "Glassmorphism." Gone are the heavy, opaque windows. V2 introduces a translucent, modern aesthetic that actually looks like it belongs on a modern OS. It’s sleek, it’s dark-mode friendly, and surprisingly, it’s readable.

Most complex scripts require multiple tabs. Here is how you create a tabbed interface in C00lgui V2: Gone are the days of the default grey box

local gui = shared.C00lgui.new(Title = "Multi-Tool Hub")
local combatTab = gui:AddTab("Combat")
local visualsTab = gui:AddTab("Visuals")
local utilityTab = gui:AddTab("Utility")
-- Combat features
combatTab:CreateSlider("Aimbot FOV", 0, 360, 120, function(value)
setAimbotFOV(value)
end)
-- Visuals features
visualsTab:CreateColorPicker("Chams Color", Color3.new(1,0,0), function(color)
setChamsColor(color)
end)
gui:Open()

Nothing is more frustrating than reopening a game and having to re-toggle all your hacks. C00lgui V2 includes a built-in State Manager. When you close the GUI, it saves your current configuration to a local JSON file. Re-inject the script, and C00lgui V2 auto-loads your last settings. This is a game-changer for grinding games like Blox Fruits or Pet Simulator.

One of the most annoying aspects of old GUIs was "drag lag"—the delay between moving your mouse and the window moving. C00lgui V2 introduces frame-independent dragging. Even if your executor is spamming errors or the game is running at 20 FPS, the GUI moves butter-smooth.

C00lgui V2 represents a second-generation iteration of a lightweight, custom graphical user interface (GUI) library. While not a mainstream enterprise framework (like Qt or WPF), C00lgui V2 has carved out a niche within enthusiast communities—particularly in game modification, simulation tooling, and “external overlay” development—due to its balance of visual flair, low system footprint, and ease of integration. This suggests the developer understood not just automation,
