Hi Product Hunt! I'm Alexandr, and I build this on my own.

I kept getting .unitypackage files — Asset Store packs, VRChat avatars from Booth — that I only wanted in Blender. Installing a 5+ GB editor just to look inside felt wrong, and the FBX alone loses Unity's material assignments, so textures had to be relinked by hand.

So the tool does it in the browser: it unpacks the archive locally, restores the real paths, reads Unity's materials, prefabs and scenes and follows their GUID links, then exports a GLB with the textures already connected. Nothing leaves your computer.

What it does today:

• 3D preview of models, prefabs and whole scenes

• GLB export — a single file, or a bulk ZIP that keeps the Unity folders

• the original FBX, the raw files, or all textures as PNG (PSD, TIFF, EXR, HDR, DDS converted)

• humanoid avatars (unitypackage, PMX, FBX, GLB) to VRM 1.0, plus a VRM viewer

• 9 interface languages

Honest limits: custom shaders become standard PBR materials, so stylized looks can change; very large scenes need a lot of memory; it reads .unitypackage archives, not built games or AssetBundles.

Opening, previewing and single exports are free with no sign-up. Pro is a one-time payment that removes the weekly limit on bulk ZIP exports.

I'd love to hear which packages break it and what you'd want next.
