It is the first open-source solution featuring true 2D math input combined with powerful syntax sugar and the fastest granular interactive evaluation engine, making it ideal for advanced mathematical workflows, scientific computing, and data exploration.
The notebook combines live code in WL, JS, Mermaid and many more, GUI blocks for user input, equations, narrative text, visualizations, interactive widgets.
WLJS Notebook is free software based on the Wolfram Engine.
You don’t need Mathematica installed to use WLJS Notebook. No subscription required—just a one-time registration at wolfram.com for personal use.
See the license agreement for details.
Developed through the collaboration of physicists and programmers. Designed for real-world applications in science ⚗️, math 🧮, and education 📚.

Pages featuring real-world problems solved using WLJS Notebook, published as interactive notebooks running in your browser.
Notebooks presented as static web pages showcasing various examples demonstrating the power of Wolfram Language and our frontend.
Blazing-fast dynamics, GUI components, and powerful Mathematica syntax enhancements out of the box.
- No more static pre-rendered graphics! Most native Mathematica plotting functions are supported.
- Optimized for real-time dynamics and interactivity.
The entire scene above is generated on the Wolfram Kernel and streamed to WebGL buffers via low-latency binary sockets.
