Roblox UI planning with script export
Roblox GUI Maker
Design a Roblox ScreenGui layout in the browser, arrange common UI components, tune the properties players actually notice, then export Luau that recreates the interface in Roblox Studio.
How to make a GUI in Roblox Studio
A good Roblox GUI starts with the job the player needs to complete. Menus, reward panels, shop buttons, and mobile controls all have different spacing needs. Start with one core frame and make sure it reads at a glance before adding decoration. On desktop, the player has space for a wider panel. On mobile, the same interface needs larger tap targets and less text. Use the screen presets in this tool to catch those problems early instead of discovering them after you paste a script into Studio.
In Roblox Studio, UI normally lives inside a ScreenGui under StarterGui. A ScreenGui can contain Frames, TextLabels, TextButtons, ImageLabels, ImageButtons, TextBoxes, and ScrollingFrames. Roblox positions these with UDim2 values. This MVP exports offset-based UDim2 values because they are predictable when you are sketching a first layout. Once the design is in Studio, you can convert important pieces to scale values, add constraints, or connect button scripts for your game logic.
Build the hierarchy before polishing colors
Roblox UI gets easier when the hierarchy is clean. Put related objects inside a Frame, then move the Frame instead of trying to reposition every label and button one by one. In this editor, adding a component while a Frame or ScrollingFrame is selected places the new child inside that container. That mirrors the way a ScreenGui tree should be organized in Studio and makes the generated script easier to read.
Use UICorner and UIStroke sparingly. Rounded buttons and a thin stroke can make a menu feel finished, but too many glowing borders make the screen harder to scan during play. As a Roblox player, the first test is simple: can I understand the next action in less than a second? If the button text, contrast, and spacing pass that test, then gradients and images can support the design without carrying it.
Export and paste the Luau
When the layout is ready, copy the generated Luau. For quick testing, paste it into a LocalScript while the game is running so it can access the local player's PlayerGui. For a permanent interface, inspect the created ScreenGui and move the finished objects into StarterGui. The generated code uses Instance.new calls and explicit property assignments, so it remains readable instead of hiding the UI inside a black-box export.
Image components accept a Roblox asset ID or an rbxassetid URL. Text components export Text, TextColor3, TextScaled, TextSize, and Font. Containers can include UIPadding and UIListLayout. This does not replace Studio's final preview across every device, but it speeds up the slow first step: getting a real ScreenGui structure on screen without manually creating every object from scratch.
Use Luau as the source of truth
The main export path is Luau because a creator can paste it into Studio, read every instance and property, and fix a line without reverse engineering a generated file. Saved behavior bindings export as a second Luau script; place that script in a LocalScript under the generated ScreenGui so button interactions can find the same instance names.
The RBXMX download is useful for experimentation and instance-tree inspection, but it should be treated as a helper rather than the final authority. Before publishing a game UI, run the exported ScreenGui in Studio, test it in Play Solo, and check mobile controls at phone size. A Roblox player cares less about the export format and more about whether the button is readable, tappable, and responsive.
FAQ
Does the GUI Maker export a real Roblox script?
Yes. The export is pasteable Luau that creates a ScreenGui and Roblox UI instances with properties such as Size, Position, AnchorPoint, colors, text, images, corners, strokes, gradients, padding, states, and layout helpers.
Should I use Luau or RBXMX first?
Use Luau as the primary path because it is readable, easy to paste, and easy to debug in Studio. RBXMX export is included as an experimental import helper for users who want to inspect a generated instance tree.
Does this run inside Roblox Studio?
The browser editor runs on Roblox Maker. The exported script is meant for Roblox Studio, where it can create the UI under PlayerGui while testing or StarterGui when you are ready to keep it.
Can button behavior be exported too?
Yes. Save behavior bindings in the editor, then copy or download the generated behavior bindings Luau and place it in a LocalScript under the exported ScreenGui.
Is the preview exactly the same as Roblox?
It is a planning preview, not the Roblox renderer. It maps the important layout and style properties so you can build the structure faster, then do final polish in Studio.
