5 Free AutoCAD Alternatives for 2025
Discover powerful free alternatives to expensive AutoCAD software, including online CAD viewers, open-source tools, and web-based solutions.
Why Look for AutoCAD Alternatives?
AutoCAD is the industry standard for computer-aided design, but its high subscription cost (starting at $1,865/year) makes it inaccessible for many users. Whether you're a student, freelancer, or small business owner, these free AutoCAD alternatives offer powerful CAD capabilities without the hefty price tag.
AutoCAD Pricing Reality Check
- • AutoCAD LT: $420/year (2D only)
- • AutoCAD: $1,865/year (2D + 3D)
- • AutoCAD Plus: $2,040/year (includes additional tools)
For occasional use or viewing CAD files, these costs are often unjustifiable.
