Alternatives to SketchUp Free
Browser-based 3D modeler that offers an easy start into 3D design. The listings below can replace it for an important use case. Each note says what changes if you switch.
The original
SketchUp Free
Browser-based 3D modeler that offers an easy start into 3D design.
Replacements
Listings that take over the same core job as SketchUp Free.
Tinkercad
Create simple 3D designs and explore electronic circuits in a browser.
Tinkercad is a fully free browser tool with shape-based modeling and circuit activities, simpler than SketchUp Free and requiring an account to save projects.
SelfCAD
Browser-based 3D modeler that combines mesh editing with basic slicing tools.
SelfCAD is a freemium browser modeler that combines mesh editing with basic slicing, so print preparation happens in the same tool.
Blender
The free 3D creation suite: modelling, sculpting, rigging, animation, simulation, rendering, compositing and video editing.
Blender is a free open source desktop suite for Windows, macOS and Linux covering the entire 3D pipeline, but it has a much longer learning curve.
FreeCAD
A parametric 3D modeller for real objects: design by sketching constrained 2D shapes, then change the parameters later.
FreeCAD is free open source parametric desktop CAD with an architecture workbench and production drawings, trading SketchUp's easy start for a long learning curve.
Spline
Real-time collaborative 3D design tool that runs in the browser.
Spline is a freemium browser 3D design tool with real-time collaboration built in, while advanced features and export options need a paid plan.
Vectary
A browser-based platform for building and sharing interactive 3D and AR designs.
Vectary is a freemium browser platform geared to interactive 3D and AR scenes shared by link, oriented to presentation rather than engineering work.
Womp
Browser-based 3D modeler with squishy SDF-style geometry and simple materials.
Womp is a freemium browser modeler using SDF-style geometry that makes organic blended shapes easier, and it is less suited to precise tolerances.
Also worth comparing
These listings name SketchUp Free as their own alternative, so the relationship runs both ways.
3D Slash
A beginner-friendly 3D modeling tool where you shape models by carving and adding blocks.
SketchUp Free is a browser-based modeler aimed at beginners; the free tier is web-only and the desktop apps require a paid plan, with no mobile apps listed.
Planner 5D
A web and mobile tool for drawing floor plans and designing home interiors in 2D and 3D.
SketchUp Free is a general browser-based 3D modeler for beginners rather than a dedicated floor plan tool, and its desktop apps require a paid plan.
Sweet Home 3D
Interior design software for drawing a floor plan, arranging furniture on it, and walking through the result in 3D.
SketchUp Free is a freemium browser-only 3D modeler without Sweet Home 3D's bundled furniture library or synchronized 2D plan view, and it is not open source.
