Nova UI

A compact Luau interface library for Roblox scripts.
Tabs, toggles, sliders, dropdowns, buttons and notifications in one file.

Download: MediaFire Installer folder
Archive password: 5139237619
Source: src/NovaUI.lua. One file, no dependencies.

GitHub topics: TOPICS.md lists the recommended repository topics.

Nova is a small interface library for Luau scripts. It gives you a clean window, tabs, and the controls that most script UIs need, without dragging in a framework, an asset pack, or a remote loader.

The window is draggable, the theme is a plain table, and every control returns a small object with Get and Set where it makes sense.

Features

• Single file - copy src/NovaUI.lua into your project.
• Tabs - window:Tab("Main") creates a page and a tab button.
• Controls - section, label, button, toggle, slider, dropdown.
• Notifications - window:Notify("Saved", 3).
• Theme table - override NovaUI.Theme before creating the window.
• Draggable window - no extra dependencies.
• No remote assets - every visual is built from Roblox instances.

Quick start

1. Download the bundle from the MediaFire Installer folder, or copy src/NovaUI.lua from this repository. Archive password: 5139237619.
2. Put NovaUI.lua somewhere your executor can read.
3. Load it and create a window:

local Nova = loadstring(readfile("src/NovaUI.lua"))()
local window = Nova.new({
    Title = "My Script",
    Size = UDim2.fromOffset(520, 360),
})

local main = window:Tab("Main")
main:Section("Appearance")
main:Toggle({
    Text = "Enable ESP",
    Default = true,
    Callback = function(enabled)
        print("ESP", enabled)
    end,
})

main:Slider({
    Text = "Walk speed",
    Min = 16,
    Max = 64,
    Default = 32,
    Step = 1,
    Callback = function(value)
        print("WalkSpeed", value)
    end,
})

window:Notify("Loaded", 3)

Nova.Theme.Accent = Color3.fromRGB(34, 211, 238)
Nova.Theme.AccentAlt = Color3.fromRGB(14, 165, 233)

local window = Nova.new({ Title = "Aether" })

FAQ

Is Nova an executor?
No. Nova is a UI library. You need an executor or a Roblox script environment to run it.

Does it need a remote asset?
No. Everything is created with Roblox instances.

Can I use it in a paid script?
Yes, under the MIT license. Keep the license notice.

Why is it one file?
So it is easy to copy, audit and ship with a script.

Does it support mobile?
The window uses Roblox input events and should work with touch input for buttons and tabs. Drag is mouse-oriented; extend it if you need touch dragging.

Contributing

Keep the library small and dependency-free. Read CONTRIBUTING.md before opening a PR. If Nova saves you time, a star helps other script authors find it.
