NullXray is a free safety and inspection tool for VRChat avatar packages.Before you import an avatar or prefab someone sent you, drag the .unitypackage onto NullXray. In seconds you see whether it is hiding anything dangerous, plus a full breakdown of what is inside.What it checks:- Safety: flags hidden scripts and DLLs, code that runs on import, and the real red flags (credential/token theft, shell launch, obfuscated loaders). Known tools like Poiyomi and VRCFury are recognized, so you do not get false alarms.- Contents: every asset, with file types, sizes, and thumbnails.- Performance: texture VRAM and material load, rated in VRChat terms.- Broken-link and missing-script checks: know if it will import clean.- Color and license: the avatar's palette, plus any readme or usage terms surfaced up front.It is fully static. NullXray reads the package, it never imports, compiles, or runs anything inside it. It is a heuristic scanner, not antivirus: it shows you the risk so you decide.Comes with a small Unity plugin that adds a Nullcore menu to your project for cleaning missing scripts.Free, no account needed.Note: the installer is not code-signed, so Windows SmartScreen may warn on first download.
