Light JavaScript Playground: A Standalone HTML/CSS/JS Editor

Light JavaScript Playground is a Chrome Extension providing a simple solution for testing and experimenting with HTML/CSS/JS directly in your browser. The standalone nature of the extension means that it doesn't rely on a backend, keeping your codes private unless exported to platforms like jsfiddle.net. While light by design and not feature-dense, it sports enough flexibility for most development needs and supports external libraries like jQuery and Bootstrap via CDNs. Export your work to a JS fiddle directly or contribute to its open-source code available on GitHub.

Great application. Allows for entirely local testing/development of simple JS programs. Has syntax highlighting, a well laid out 4-panel [css, js, html, run] layout, and easy upload to JSFiddle. Exactly what I was looking for! Thank you!
