DeviceLab
Renders your real ScreenGui on phone, tablet, desktop and console viewports side by side, live, in a Studio dock — no playtest.
What you get
It names what is broken: elements off screen, buttons under the topbar or in a notch margin, touch targets too small, text too small to read. Click a finding to outline it on every device.
How it holds up
Presets are read straight out of Studio's own Device Emulator, and your UI is laid out by Roblox's engine rather than a re-implementation. Measured against the emulator on four device classes: 0.00 px difference in position and size.
What it does not do
Screen UI only in this version. Never modifies your place; every script is stripped from the preview. Works offline, no telemetry.
The listing, word for word
Your Roblox UI may look perfect in Studio — until a player opens it on another device.
DeviceLab helps Roblox developers compare the same selected ScreenGui hierarchy across multiple enabled device views instead of repeatedly checking one device at a time.
Review your UI across phone, tablet, desktop, and console-style viewport setups. DeviceLab flags specific compatibility concerns such as off-screen elements, clipping, unsafe-area concerns, small touch targets, small text, and layout changes that need attention.
When a concern is found, DeviceLab helps connect the preview issue back to the source UI Instance so you can understand what needs fixing.
Built for Roblox UI iteration and compatibility reviews. DeviceLab improves your QA workflow — it does not replace full gameplay or runtime testing.
ONE UI. MULTIPLE DEVICES.
