libfive Studio
What libfive Studio is
libfive Studio is free desktop software for script-based solid modeling using the libfive kernel. Designs can be written in Python 3 or Guile Scheme, with code executing live in a background thread; Guile execution is sandboxed. Users can also click and drag models, and Studio back-propagates those edits into the script. The functional geometry kernel supports constructive solid geometry, arbitrarily high resolution, blends, and warps. The wider stack includes Python and Guile bindings, a standard shape-and-transform library, a C API, and a C++ library for building tools or applications. Studio exports STL and SVG files. A macOS app supports version 10.14 or later; Linux and Windows users build from source, with stated support for Ubuntu 20.04 LTS and Windows 10 source builds. The project is alpha software for experimentation and personal projects, and support is best-effort through GitHub issues. Core libraries use MPL licensing and the GUI uses GPL.
Who it suits
libfive Studio suits people exploring generative design, personal modeling projects, or tools built around its scripting and library stack. It is less suited to mission-critical work because the maker labels it alpha software.
What it does well
- Free open-source desktop software
- Python and Guile scripting
- Direct edits back-propagate into scripts
- Constructive solid geometry and high resolution
- STL and SVG export
What to know first
- Alpha software
- May not suit mission-critical applications
- Linux and Windows require source builds
- Support is best-effort through GitHub issues

Verdict
libfive Studio offers a script-centered modeling workflow with direct manipulation and a functional geometry kernel. Its free license and developer APIs support experimentation, while alpha status and source-build requirements may affect adoption.
