WLJS Notebook
Open-source Notebook interface for Wolfram Language
Typeset math input, syntactic sugar, multiple languages, and a fast, granular evaluation engine
Plot[1/x, {x,0,1}] 🪄 Everything you need to build amazing sharable notebooks
Feels like Mathematica and Jupyter
WLJS Notebook feels and works like Wolfram Mathematica (and it can open .nb files) and has a flat and minimal notebook structure like in Jupyter Lab.
Interactive & Powerful
Optimized for interactive computing and allows to make complex real-time visualizations. From the high-level Manipulate to low-level graphics primitives
Driven by real-world problem solving
Developed through the collaboration of physicists and programmers at University of Augsburg 🇩🇪 it is continuously refined in a feedback loop.
Super portable
Export and share your notebook as a standalone or embeddable .html or .mdx file—plots stay interactive, and sliders remain draggable.
Batteries included
More than 200 importers/exporters formats, 3000 functions. Vast standard library of Wolfram Engine is ready for every computational need.
Javascript Sandbox
First class support of Javascript cells with a dedicated communication channel to Wolfram Kernel. Use any library from web to enhance your visuals.
Digitally Signed
Our releases are digitally signed and checked by SignPath Foundation and Apple
