Floorplanner vs QCAD Professional

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.

QCAD Professional is 2D CAD software for technical drawings such as building plans, mechanical parts, and diagrams. It runs on Linux, macOS, and Windows. Drawing tools include layers, blocks, construction and modification commands, object snaps, measuring, and scaled multipage printing. The Professional edition reads and writes DWG and DXF through version R32, covering 2018–2026, and supports PDF, SVG, bitmap, DWF, and DGN formats. Its Library Browser offers more than 5,000 CAD parts as free add-ons. An ECMAScript (JavaScript) interface supports creating and modifying entities and building interactive CAD tools. Command-line utilities batch-convert drawings to PDF, SVG, bitmaps, and other formats. QCAD offers Professional trial packages and a free, open-source Community Edition. The single-user perpetual license can be installed on multiple computers and operating systems for one user, with new-version updates included for one year. The download plan costs 48.00 USD once.
