OpenSCADFree (open source)

OpenSCAD is a free, open-source program that builds solid 3D models from a text script instead of interactive drawing. Changing a parameter regenerates the whole model, which makes it popular for customizable 3D-printable parts. It runs on Windows, macOS and Linux.

5 OpenSCAD Alternatives in 2026

Considerations for OpenSCAD

  • No interactive sketching or mouse-driven modeling
  • Fillets and organic shapes are awkward to express in code
  • Not suited to large assemblies or production drawings
5 alternatives comparedConfirm current terms with providers
FreeCAD
Best for: Open-source parametric 3D CAD for engineering
FreeOpen Source
FreeCAD is an open-source parametric 3D modeler for designing real-life objects of any size, from mechanical parts to buildings. It runs on Windows, macOS and Linux, with workbenches for part design, sketching, assemblies, 2D drawings, FEM analysis and CAM.
  • History-based parametric modeling with a constraint sketcher
  • Assembly, TechDraw drawing, FEM and CAM workbenches built in
  • Free for any use, including commercial, on Windows, macOS and Linux

SolveSpace
Best for: Lightweight constraint-based parametric CAD
FreeOpen Source
SolveSpace is a free (GPLv3) parametric 2D and 3D CAD tool built around a geometric constraint solver. It models parts with extrudes, revolves, helixes and Boolean operations, can simulate planar and spatial linkages, and exports STL, STEP, DXF, PDF and SVG.
  • Constraint-based parametric sketches and 3D parts
  • Mechanism simulation with pin, ball and slide joints
  • Exports STEP and STL for CAM and 3D printing, and DXF or SVG for laser cutting

Tinkercad
Best for: Beginner 3D design in the browser
Free
Tinkercad is Autodesk's free browser-based app for 3D design, electronics circuits and code blocks. Shapes are combined and subtracted by drag and drop, which makes it a common first step for students and 3D-printing hobbyists before moving to full CAD.
  • Runs in a web browser with no installation
  • Drag-and-drop shape modeling with STL export for 3D printing
  • Circuits and Codeblocks workspaces for teaching

Onshape
Best for: Browser-based CAD with built-in version control
Free
Onshape is cloud-native parametric CAD from PTC that runs in a web browser and on iOS and Android, with nothing to install. Version history, branching and real-time collaboration are built in. The free plan is for non-commercial use only and makes every document public.
  • Runs in the browser on any OS, including Linux and Chromebooks
  • Built-in version control with branching and merging
  • Several people can edit the same design at the same time
Free tier: Listed as free — verify limitsPricing: Free (public, non-commercial) / $1,500/yr Standard / $2,500/yr Professional
