Score: 6.7/10 (Innovation: 6, Technical: 7, Documentation: 4, Utility: 7)

Stonn is a federated civil engineering viewer that natively renders LandXML, IFC 4.3, GeoJSON, and TopoJSON in a single 3D scene without conversions or plugins. It addresses the real pain point of siloed infrastructure data formats, and its demonstrated adoption by survey teams and ability to handle billions of triangles suggests strong utility.

Target audience: civil engineers, surveyors, infrastructure data engineers
