Short verdict
Archshaper Site Analysis is designed for quick, consistent architectural diagram sets and preliminary environmental context. Autodesk Forma Site Design serves a different need: changing building massing while evaluating environmental performance. QGIS is stronger for custom data analysis, and Ladybug Tools for specialised climate workflows.

Official product detailsFrequently asked questions
What is the best site analysis software for architects?
It depends on the deliverable. Archshaper focuses on clear diagrams, Autodesk Forma supports environmental feedback on design models, QGIS is strong for custom spatial data, and Ladybug Tools supports specialist climate workflows.
Does Archshaper offer sun, wind and noise analysis?
Yes. Site Analysis includes selected sun and shadow diagrams, regional wind references, relative wind exposure and diagrammatic noise views. These are not validated CFD, measured acoustic or regulatory daylight studies.
Which site analysis software is free?
QGIS is open source and free. Ladybug Tools is also open source but a Rhino-based workflow requires access to Rhino. Other providers have varying previews, free tiers or paid exports.
Can I export architectural site analysis diagrams?
Several tools offer SVG, PDF or other output options. For Archshaper, select the analyses and check the export dialog for the formats and credit cost currently available.
