QCAD
QCAD is an open-source 2D computer-aided design (CAD) application developed by RibbonSoft, designed for creating technical drawings such as architectural plans, mechanical parts, schematics, and diagrams. Built on the Qt framework, it runs natively on Windows, macOS, and Linux, making it one of the few truly cross-platform CAD solutions. QCAD offers a comprehensive set of 2D drafting tools including layers, blocks, hatching, dimensioning, and scripting via ECMAScript (JavaScript). While the community edition is open-source and free, a commercial Pro version adds DWG import/export support and additional features. Its small footprint, clean interface, and low cost make it ideal for hobbyists, students, small businesses, and professionals needing straightforward 2D drafting without subscription overhead.

Expert Q&A
?What is QCAD used for?
QCAD is an open-source 2D CAD application for creating technical drawings such as architectural plans, mechanical parts, electrical schematics, and diagrams. It is widely used by hobbyists, students, and small businesses for its simplicity and affordability.
?How much does QCAD cost?
QCAD Community Edition is free and open-source. The Professional version costs approximately $39–$49 for a perpetual license and adds DWG import/export, additional part libraries, and commercial use rights.
?Is there a free version of QCAD?
Yes. QCAD Community Edition is completely free and open-source under the GPL license. It includes all core 2D drafting tools but lacks DWG support, which is available in the paid Pro version.
?What operating systems does QCAD support?
QCAD runs on Windows, macOS, and Linux. It is one of the few CAD applications offering native support for all three major desktop platforms.
?Which file formats does QCAD support?
QCAD supports DXF natively in the free version. The Pro version adds DWG import/export. Both versions support SVG and PDF export. Check the vendor's documentation for the complete list.
?What are the best alternatives to QCAD?
The closest alternatives within the 2D CAD space are LibreCAD (also open-source), DraftSight (freemium DWG CAD), and BricsCAD (paid DWG-compatible). For hobbyists, FreeCAD offers 2D and 3D capabilities. Compare them side-by-side using the CADGuide comparison tool.
