A clearer 3D handoff
Check a GLB/glTF batch, compare it with your previous report and keep the original files together. $29 per batch, with private download access for 30 days from preparation. Preparation happens before payment.
Prepare your ZIP
Include batch.json, your assets and every local buffer or image they reference. Use ordinary relative file names. External URLs and parent-directory paths are unsupported. The supported workload is 1–20 assets, a 16 MiB upload and 64 MiB expanded archive.

Choose your profile
web-light-v1 checks a 5 MiB asset-and-resource budget, 100,000 triangles and 2048-pixel texture dimensions. core-handoff-v1 checks 16 MiB, 1,000,000 triangles and 8192-pixel textures. Extensions outside the disclosed profile are flagged for review.
The report contains technical findings and the selected profile checks. It does not repair assets, judge appearance, certify renderer compatibility or measure device performance. A finding does not establish that an asset will fail in your application.
The free Khronos single-asset validator remains available. This service adds batch handling, profiles, comparisons and private packaged delivery.
