Write, run, and test JavaScript snippets & JSON offline
A simple playground to write, run, and test JavaScript snippets, with an in-UI console. Built for quick experiments, debugging, learning, testing ideas, and working with JavaScript without needing a full development environment. This tool is offline by design, providing a robust JavaScript playground directly within Chrome.
This idea came while I was preparing for a JavaScript interview.
There are plenty of online JavaScript playgrounds, but I found them surprisingly distracting—you open the browser to code, and the internet is right there to pull your attention elsewhere. Offline editors, on the other hand, often feel like full-blown IDEs when all I wanted was something simple.
So I built Offline JavaScript Playground: a focused JavaScript editor and runner that works entirely offline. No Node.js, no VS Code, no npm, no setup - just open it and start experimenting with JavaScript.
It’s intentionally lightweight and built with **pure JavaScript, without frameworks**.
The goal is simple: **open → write JavaScript → run → learn.** 🚀
