Top Recommended Replacements
FreeCAD (CAM Workbench)
Best Overall FOSS Alternative
Why we like it
Complete integrated CAD/CAM environment; the CAM Workbench (formerly Path) supports 2.5D and 3D milling; extensive library of open-source post-processors for GRBL, LinuxCNC, and Fanuc.
Keep in mind
The 3D surfacing strategies are still considered experimental; steeper learning curve for users used to dedicated CAM interfaces.
Autodesk Fusion (Personal Edition)
FREEBest Professional Features for $0
Why we like it
The most polished UI in the market; includes high-speed machining (HSM) kernels; handles 2.5-axis and 3-axis milling, turning, and waterjet/laser cutting for free.
Keep in mind
The free version limits rapid feed rates, restricts simultaneous 4/5-axis machining, and limits the number of 'active' editable documents.
Blender CAM
Best for Artistic/Organic CNC
Why we like it
Leverages Blender's powerful 3D engine for complex artistic reliefs and textures; excellent for 3-axis relief carving and mold making; 100% free.
Keep in mind
Not designed for precise mechanical engineering; requires a solid understanding of Blender's unique interface.
HeeksCNC
Best for Lightweight Machining
Why we like it
Minimalist and fast; great for simple mechanical parts and 2.5D pocketing/contouring; includes a simple integrated CAD environment.
Keep in mind
Development has slowed in recent years; limited support for complex 3D toolpath strategies.
PyCAM
Best for Educational/DIY Use
Why we like it
Works directly with STL files; generates standard G-code for 3-axis mills; simple to use for roughing and finishing passes.
Keep in mind
Computationally slow for large or complex high-polygon models; limited feature set compared to professional suites.
jscut
Best for Laser/CNC Routers
Why we like it
Zero-install web-based CAM; converts SVG files to G-code instantly; perfect for flat-sheet parts and simple engraving.
Keep in mind
No 3D capability; strictly for 2D/2.5D work on routers or laser cutters.
Camotics
Best for G-Code Simulation
Why we like it
Does not generate toolpaths, but provides world-class 3D simulation of G-code; essential for verifying toolpaths before running them on a real machine.
Keep in mind
Only a simulation tool; must be paired with another software to generate the initial G-code.
DeskProto (Free Edition)
FREEBest for 3D Reliefs
Why we like it
Very intuitive workflow; the free edition supports STL and DXF files for 3-axis milling; great for model makers and jewelers.
Keep in mind
Free version is limited in terms of advanced optimization and simultaneous multi-axis control.
Estlcam (Demo Mode)
FREEBest for Desktop CNCs
Why we like it
Extremely popular for Stepcraft and hobby routers; intuitive 2.5D features; the demo version is fully functional with only a startup delay.
Keep in mind
Proprietary software; focused primarily on 2D/2.5D and simple 3D, lacks industrial multi-axis control.
OpenSCAD
Best for Programmatic Design
Why we like it
Allows for code-based modeling of parts; perfect for parametric jigs and fixtures; can be paired with FreeCAD for toolpath generation.
Keep in mind
No native CAM functionality; requires an external tool to turn designs into G-code.
FreeMILL
FREEBest Entry-level Plugin
Why we like it
A free module for Rhino and VisualCAD; excellent for basic 3-axis roughing and finishing from 3D models.
Keep in mind
Very limited toolpath strategies; mostly intended as a gateway to MecSoft's paid professional CAM products.
DXF2GCODE
Best for Simple 2D Profiling
Why we like it
Extremely lightweight; converts 2D DXF drawings to G-code for milling, laser, or plasma cutting; supports tool compensation.
Keep in mind
Purely 2D; lacks a 3D visualization environment.
