gltf.report

glTF Report is a browser tool for inspecting 3D models in the glTF 2.0 format: drop in a .gltf or .glb file to view it, read its structure and see its validation report. Its Script tab runs the glTF Transform scripting API, so a model can be optimised or cleaned up in place without installing anything. Designers and 3D developers use it to check and slim down models before putting them on the web.
