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.
FreeMILL
FREEBest for Quick 3D Toolpaths
Why we like it
A subset of MecSoft's commercial software; 100% free with no line-of-code limits; excellent for creating 3-axis roughing and finishing paths for mills and routers.
Keep in mind
Very limited toolpath strategies; mostly intended as a gateway to paid professional products like VisualCAD/CAM.
Blender CAM
Best for Artistic/Relief Work
Why we like it
Leverages Blender's powerful 3D engine for complex organic 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.
DeskProto (Free Edition)
FREEBest for 4-Axis Rotary
Why we like it
Unique among free tools for offering solid 4-axis rotary support in the free edition; very intuitive workflow; imports STL, DXF, and SVG files.
Keep in mind
Free version is limited in terms of high-end optimization and simultaneous 5-axis control.
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 to prevent crashes.
Keep in mind
Only a simulation tool; must be paired with another software (like FreeCAD) to generate the initial G-code.
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 DIY CNC Enthusiasts
Why we like it
Works directly with STL files; generates standard G-code for 3-axis mills; supports parallel and circular toolpaths for roughing and finishing.
Keep in mind
Computationally slow for large or complex high-polygon models; limited feature set compared to professional suites.
jscut
Best for Laser/Plasma/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 on 2.5D machines.
Keep in mind
No 3D capability; strictly for 2D profiling and pocketing on routers or laser cutters.
Estlcam (Demo Mode)
FREEBest for Desktop Routers
Why we like it
Incredibly popular for hobby routers; intuitive 2.5D features; the demo version is fully functional with only a startup delay; supports probing and leveling.
Keep in mind
Proprietary software; lacks industrial multi-tasking (MTM) and complex turning support.
Carbide Create (Free)
FREEBest for Beginners
Why we like it
Clean, modern interface; perfect for 2D and 2.5D work; includes a built-in library of materials and tools to get started quickly.
Keep in mind
Focused on basic router work; lacks advanced 3D surfacing and multi-axis features found in GibbsCAM.
CNCjs
Best Control Interface
Why we like it
A web-based interface for CNC control; works with GRBL, Marlin, Smoothieware, and TinyG; includes a 3D G-code visualizer and job management.
Keep in mind
Primarily a 'Control' tool; does not generate the initial toolpaths/G-code from a CAD model.
