Rayon

per-editor subscription with a free tier Produce & Issue Documents

Browser-based, real-time-collaborative CAD/light-BIM design tool for architects and interior designers, positioned as a lighter alternative to AutoCAD/Revit/ArchiCAD for 2D floor plans, space planning, and AI-assisted visualization.

Agent-hostile

3.4 /5 composite score

Well-funded (~$6M seed, Northzone/Foundamental, backed by Norman Foster) browser-based collaborative CAD tool with transparent per-editor pricing and a free tier, but no public API/CLI/MCP was found and data interoperability is limited to DWG/DXF file exchange.
