Floorplanner vs GstarCAD

Floorplanner is a browser-based editor for drawing floor plans and producing architectural visualizations with cloud rendering. Users create rooms, move walls, add doors and windows, and see changes in a real-time 3D view. The model library contains over 260,000 items at no extra cost. Projects can generate 2D, 3D, and photorealistic images, with advertised output up to 8K. A free account allows up to five projects; each free project supports three floors and three designs, while SD Lite exports are 960 × 540 pixels and carry a watermark. One-time credit purchases can raise projects to seven floors and ten designs per floor, remove the watermark, and unlock higher-resolution exports. Upgraded projects can add paid 3D tours and public Spaceplanner links. The editor runs in a browser without downloads or plug-ins and offers API and custom integrations.
