Alternatives to OpenSCAD
Code-based CAD for programmers
OpenSCAD ranks #12 of 13 in 3D modeling software, with an Alt Score of 32. It is licensed under GPL-2.0, free and available on Windows, macOS and Linux. 8 of 10 checklist rows are verified against a public source.
Programmers and technically minded makers who want to design 3D models by writing code rather than dragging shapes in a GUI, including hobbyists preparing parts for 3D printing and engineers who need precise, parametric geometry.
A free, open-source, cross-platform (Linux, Windows, macOS) CAD tool built around a scripting language for solid geometry, using constructive solid geometry (CSG) operations like union, difference, and intersection. Models are fully parametric, so changing a variable regenerates the whole design, and files are plain text, making them easy to version-control, script, and reuse across similar parts. It renders a preview and exports finished geometry to STL and other formats for 3D printing or downstream CAD use.
You write a script describing shapes and the boolean/transform operations that combine them, preview the rendered result in the built-in editor, and export the final solid (typically as STL) once satisfied.
