The free Roblox UI kits people actually share, and what’s inside them
Search Medium for “free Roblox UI kit” and most of what comes back is Robux generator spam. The actual kits live on the Roblox DevForum and itch.io, and the “best free UI kits” roundups I found don’t name a single one. They describe categories and tell you to go browse.
So I went through the free packs developers really pass around and wrote down what each one gives you. I make one of these myself, so take my own entry with that in mind. I’ve kept its limits in.
Everything below is as of September 2026.
First, “free UI kit” means four different things
Before comparing, it helps to know what kind of file you’re getting, because it decides how much work is left.
Image files, usually a PSD. You get a design. You still rebuild every frame and button in Studio yourself.
A .rbxm with a few screens. You drag it into Studio and the frames are there. Usually only the open and close buttons are scripted.
A library. TopbarPlus, Fusion, Iris. These are code for scripters. They give you behaviour, not a look.
A Figma file. Nice to plan with, but nothing in it imports into Roblox. It’s a picture of a UI.
UI Pack Plus (mine)
Free, on zerodev.tools. It’s a .rbxm with eight finished screens: main menu, shop, inventory, character sheet, options, trade, a confirm popup and a HUD. Plus the pieces they’re made of (panels, buttons, sliders, item cards, slots, bars and so on) so you can build screens that aren’t in the box. Everything shares one carved-stone style, so things you put together still match.
Hover and click animations work out of the box, and so does fitting the screen. It’s laid out in pixels with one UIScale at the root that follows the window, so it shrinks to fit a phone in landscape instead of breaking. You don’t write any code to get either of those.
Now the limits. It doesn’t script your game. A shop button looks and animates like a shop button, but what happens when someone buys is still your code, hooked to your game passes or currency. On a phone it’s the same layout made smaller, not rearranged. It’s one art style, so if carved stone isn’t your game, it won’t fit. And it isn’t open source: you can use it in games that make Robux, but you can’t reupload the file.
Setup is dragging the file in, then moving ShardUI into ReplicatedStorage and ShardUIPack into StarterGui. Most people who say “nothing shows up” skipped that second part.

Free Simulator UI Kit by FramedBlake
Posted on the DevForum in September 2021, 40 likes. It’s a single Photoshop file, about 7.7 MB, in a simulator style. The creator is upfront that it’s “a free kit, not meant to be the best thing in the world.”

What you get is the art. To use it you open the PSD (Photopea works if you don’t own Photoshop), export the pieces and rebuild the screens in Studio. One person in the thread couldn’t open the file at all. Good if you want to learn by building. Not a shortcut.
Biscuit’s Free UI Pack V.2
DevForum, November 2021. This one is in Studio already: a settings screen, a rebirths screen, a codes screen and a pet inventory. The author says only the open and exit buttons are scripted and “you will have to script the rest of the things by yourself.”
The replies are worth reading before you use it. People report screens that end up out of place in the mobile emulator and break when the window size changes. If your players are on phones, test it there first.
Modern GUIs Pack
DevForum, August 2022, 32 likes. A small .rbxm (24.6 KB) with a search screen, a settings screen and a shop. When someone asked if it was fully scripted, the creator said no, only the toggle button is.
It’s clean and it’s tiny. Three screens is also not much of a game.
FREE Cartoony Roblox UI Pack by Zxgly
On itch.io, and probably the strongest free pack right now. It’s a 17 KB .rbxm in a cartoony simulator style with seven screens: inventory, store, settings, promo codes, quests, a daily rewards calendar and player stats. Unlike the DevForum packs, it’s scripted beyond open and close. There’s a UI manager, tween animations and sound built in. It’s also still maintained, with five updates since December 2025.
One thing from the comments: someone reported image IDs in the inventory showing up as private, so the images didn’t load. The author said it would be fixed in an update. Worth checking after you import it.
If you want the most scripting for free, start here.
General UI Kit by RBLX Essentials (paid, for comparison)
Not free, but it’s what the free packs get compared to, so it belongs here. It’s $14.99 on itch.io. You get 14 menus and 12 HUD buttons, tag-based, with live data binding. RBLX Essentials does give away some smaller system kits for free, like a notification kit. The General UI Kit itself isn’t one of them.
How to pick one
A few questions sort them out fast.
Does it open in Studio, or is it an image file? If it’s a PSD, budget the time to rebuild it.
Whole screens or loose parts? A pile of buttons still leaves you designing the layout.
What exactly is scripted? Almost every free pack scripts open and close and stops there. That’s normal, just know it going in.
How does it look on a phone? In Studio, turn on Device emulation and pick a phone in landscape. It takes a minute and it’s where most free packs fall apart.
Can you use it in a game that earns Robux? Read the licence, some packs are fine with it and some don’t say.
If one of these helped you, or you know a free pack I missed, tell me in the comments. I’ll add it.
