AutoCAD
Autodesk's 2D drafting and 3D CAD application, available on the desktop and in the browser.
AutoCAD uses the native DWG format and covers 2D drafting and 3D modelling across desktop and web, with expensive licensing and a required Autodesk account.
BricsCAD
Native-DWG CAD software with 2D drafting, 3D modeling, BIM, and mechanical variants.
BricsCAD offers native DWG with 2D drafting, 3D modelling and BIM variants, and runs on Windows, macOS and Linux rather than Windows only.
ZWCAD
Commercial 2D drafting and 3D CAD software with native DWG compatibility, offered as an AutoCAD alternative.
ZWCAD is a Windows DWG-compatible CAD package with a perpetual licence option and 2D and 3D work, but has a high upfront cost.
GstarCAD
Commercial CAD software for 2D drafting and 3D design that works natively with DWG files.
GstarCAD works directly in DWG on Windows, covers 2D drafting and 3D design, and sells mechanical and architectural industry editions as separate products.
progeCAD Professional
AutoCAD-compatible 2D and 3D DWG CAD software for Windows sold with a perpetual licence.
progeCAD Professional offers AutoCAD-style DWG drafting on Windows with a perpetual licence and imports Revit, IFC, STEP and PDF files.
nanoCAD
A DWG-compatible 2D drafting and 3D modelling CAD platform for Windows with optional modules.
nanoCAD is freemium DWG-compatible CAD for Windows with modular add-ons for mechanical, construction and survey work, and parametric constraints in the Pro bundle.
LibreCAD
A 2D CAD program for DXF and DWG drawings, built from the free edition of QCAD.
LibreCAD is free and open source on Windows, macOS and Linux, reads DWG and writes DXF, DWG, PDF and SVG, but is strictly 2D.
QCAD
A 2D CAD program for technical drawings: floor plans, mechanical parts, schematics and diagrams, with DXF and DWG in and out.
QCAD is open source 2D CAD with DXF input and output on all desktop platforms, while DWG support sits in its paid Professional edition.
Also worth comparing
These listings name DraftSight as their own alternative, so the relationship runs both ways.
TurboCAD
Commercial 2D and 3D CAD software for drafting and mechanical and architectural design on Windows and Mac.
DraftSight is Dassault Systèmes' paid Windows CAD focused mainly on 2D DWG drafting, with less emphasis on 3D modelling.
