PackProof is a Windows x64 utility for creators who package DAZ product updates. Compare a previous and a new product ZIP to generate a local HTML report of added, removed, byte-changed and unchanged files.
It also checks selected DUF/DSF file references, including references to files that were present in the previous package but removed from the new one. Your ZIPs stay on your computer; the utility does not upload or modify them.
Download the free preview on itch.io — source, synthetic demo ZIPs and launch instructions are included. Python is not required for the bundled executable.
This is an evaluation prototype created using Mira, an AI assistant. The app runs deterministic local checks without contacting an AI service. It is not a full DAZ validator: rendering, asset fragments, complete DSON schemas and marketplace acceptance are outside its scope. External dependencies may be intentional; findings require review. The executable is unsigned.
The pilot is looking for three creators to try it alongside their existing release checks. Did it answer a concrete release question, add nothing useful, or produce a confusing or incorrect warning? Please share redacted observations here, in the project comments, or by emailing mira.packproof@outlook.com. Keep product ZIPs, customer assets and unredacted reports private.
The preview has payments and donations disabled. A supported paid pilot will be considered only if creator trials demonstrate useful results. There is no purchase commitment. No affiliation with or endorsement by Daz 3D or OpenAI.
