Hey everyone,
I wanted to use my CNC and laser more often and found that firing up a 3D CAD program was just too much, so I made RapidCAM.app. It let’s you quickly define objects and give them toolpaths, then send them right to your machine or to GSender over the network.
The app grew and is now a complete parametric 2.5D CAD/CAM.
The file format is open source with good documentation. Files are designed for use with version control and AI in mind.
The software operates locally on your machine, meaning your designs and G-code never leave your browser. It includes a full parametric sketch editor with constraint solving, variable formulas, and patterns. From there, you can generate toolpaths for profiling, pocket clearing, drilling, V-carving, V-carve inlays, rotary fourth-axis machining, laser operations, and 2.5D or 3D relief carving from imported STL files or images.
It also features 3D WebGL stock simulation, pre-flight safety checks to catch common programming errors before running, and direct G-code output for GRBL and LinuxCNC controllers. Projects save as clean JSON files that work well with version control.
It is free to use with nothing to install. I would appreciate any feedback or feature requests.
