    JSCAD (previously known as OpenJSCAD)

    JSCAD is a set of modular, browser and command line tools for creating parametric 2D and 3D designs with JavaScript code.

    There are many ways to use JSCAD:

    An online version, self hostable web based ui, as CLI (command-line interface) for server-side computations with Node.js, as well as an experimental desktop app or individual Node.js packages!!

    This repository is a monorepo (container of multiple packages and tools) maintained with Lerna

    Table of Contents


    There are different 'flavors' of JSCAD that you can use based on your needs

    • web: online (no install) simply go to
    • web: self hosted: can be found here
    • cli: command line interface : can be found here
    • desktop app: pre pre alpha work in progress can be found here!
    • node.js: custom mix and match of packages
      • all the packages are available on NPM under the '@jscad' name

    Immediate Use (no installation)

    Go to (Tested browsers include Chrome, Edge, Firefox, Opera, Safari)

    Use within a Web Site (pre built files, from GitHub)

    Please see here for details

    Use as Command Line Interface (CLI)

    Please see here for details

    Use of components and viewer in websites

    Please see here for details

    Use of the different modular components directly

    From version 1.0.0 onwards, almost all the individual parts of this project are available directly as scoped NPM packages, and can be used independently from the main repository. The full list of these is available here and here

    One example of what can be achieved with this can be found here This means you can :

    • easily create your own renderer for the 3D and 2D geometries
    • create custom UIs
    • use the specific packages as part of Node.js or Browserify projects
    • cherry pick formats you want to use for input/output without needing the dependencies of all packages
    • lots more !

    This will be expanded upon in the future, and is the backbone of the newer, modular JSCAD project.



    The various JSCAD packages and all source code are part of the JSCAD Organization, and maintained by a group of volunteers. We welcome and encourage anyone to pitch in but please take a moment to read the following guidelines.
