SpatialLens - 3D Web Page & Layer Inspector

Explodes 2D web pages into an interactive 3D view to inspect stacking contexts, z-index hierarchy, and nested DOM bounds.

Explodes 2D web pages into an interactive 3D view to inspect stacking contexts, z-index hierarchy, and nested DOM bounds. 🚀 KEY FEATURES: • Explode any page into an interactive 3D stack of its layers. • Inspect z-index, position and computed depth for each layer on hover. • Flags layers nested inside another stacking context, where a raw z-index reads differently from true paint order. • Wireframe and solo modes to isolate a single layer. • Export a spatial snapshot of the layer view as a PNG. 🔒 100% PRIVACY-FIRST: Everything runs locally in your browser. No account, no server, no analytics, no remote code. Nothing you view or type is transmitted anywhere — including to the developer.
