Scribbler

Scribbler is a browser-based JavaScript notebook that allows users to write and execute code instantly without setup or logins, combining code, text, and visual output in a notebook-style interface. It supports mixing markdown, JavaScript, HTML, and CSS, and allows easy import of ES6 packages via CDN, making it device-agnostic and completely free and open source. Unlike Jupyter Notebook, which requires a Python environment, Scribbler is designed for JavaScript experimentation and education, with plans to add collaboration features, richer sharing options, and multi-language support.
