What is the USDseal Inspector?

The USDseal Inspector is a browser-based tool for the analysis of USDZ files. It shows geometry, textures, metadata and AR Quick Look compatibility — and for sealed files checks issuer, timestamps, version history and manipulation check via USDseal signature.

Is the USDseal Inspector free and open source?

Yes. The USDseal Inspector is free, open source (Apache-2.0) and available on GitHub: github.com/KopfKinoK3/usdseal-inspector. It can be used without login, without upload and also offline.

Does the Inspector work without a USDseal signature?

Yes. The Inspector analyses any USDZ file — even without a USDseal stamp. In this case it delivers a diagnostic mode: geometry statistics, texture information, AR Quick Look compatibility and documented sources. For sealed files, the verification mode is added.

Which data leaves the browser when using the Inspector?

None. The Inspector works completely client-side — privacy by architecture. The USDZ file is analysed locally, there is no backend, no telemetry, no upload. The Inspector can also be saved as a local HTML file and used offline.

What is the difference between USDseal Inspector and USDseal (CLI)?

USDseal Inspector is the open-source verification tool in the browser — free, usable by anyone. USDseal (CLI) is the proprietary signing tool of viSales GmbH, with which files are sealed. The Inspector reads, the CLI writes.

USDseal Inspector

The USDseal Inspector is a browser-based tool for the analysis and verification of USDZ files — developed by viSales GmbH, published as open source (Apache-2.0). Drag in a USDZ file, read the result, make the decision. No login, no upload, no backend.

The Inspector is the open companion tool to the proprietary USDseal CLI.

USDseal Inspector — Disambiguation

USDseal Inspector is NOT:

not identical to USDseal (the proprietary CLI signing tool) — the Inspector reads and verifies, the CLI signs
not an upload service (the file does not leave the browser)
not a conversion tool (analysis only, no transformation)
not to be confused with USDbridge (which converts USDZ files) or USDconfig (which configures products)

The Inspector is exclusively a diagnostic and verification tool — it does not modify files.

USDseal Inspector — Positioning

The USDseal Inspector makes USDZ provenance accessible to everyone who does not want to or cannot operate a CLI environment — CMO, CSO, procurement, compliance, agency. Whoever wants to verify an incoming USDZ before approval can do so in the browser: without infrastructure, without account, without dependency on viSales.

The tool works on two levels: as a diagnostic tool it delivers structured information about any USDZ — independent of signing status. As a verification tool it checks hash chain, signature and manipulation status for USDseal-sealed files.

The offline capability (locally saveable HTML file) is deliberately designed for air-gapped environments in industry — factory networks without internet access can deploy the Inspector locally.
