ViewportGuard — Responsive UI Auditor

Find responsive UI failures before players do. ViewportGuard measures your interface as Roblox renders it, on the devices you support, and tells you which object failed, on which device, and by how much. SIX CHECKS Off-screen content. Clipped by a container. Text that does not fit. Safe-area overlap. Unreachable scrolling content. Controls under your minimum target size. SIX PROFILES Phone portrait and landscape, tablet, desktop, widescreen, console. Each names the exact Device Emulator preset. You select each profile in Roblox's own emulator. ViewportGuard recognises it, measures every object, and combines the results into one cross-profile matrix. It never changes your emulator settings. Coverage is stated before any finding. Cannot-determine carries a reason and is never a pass. No overall score. Every failure carries its measurements, and Locate in Explorer selects the exact Instance. Read-only: no network, no telemetry, your game is never modified.
