Archistar vs Atlasly

Archistar has no write-up on Specifiction yet; its figures are above.

Atlasly provides early-stage site intelligence for architects, including first-pass screens of planning, flood, heritage, and related constraints. Its floor plan generator turns prompts into schematic 2D concept diagrams for ideation, not construction drawings. The free tool allows three generations per day without signup; free outputs are PNG, while DXF and DWG exports require an account. Atlasly says automated reports generate PDF site packs in under 60 seconds. Walkability AI provides pedestrian-network isochrones, four persona presets, weighted amenity categories, site comparisons, and GeoJSON, Shapefile, and SVG exports. Users can access Claude and ChatGPT through Atlasly’s hosted MCP server, and a Forma Site Design extension is listed. Atlasly says its earlier REST contract has been withdrawn, its OpenAPI document has no callable operations, and the REST API is not ready for client generation. The Starter plan is free, while Professional is £15 a month billed annually and Teams is £159 a month billed annually; both paid plans include a 14-day trial. Atlasly is a product of Parallel Labs Ltd, which works from Manchester, United Kingdom.
