About this playground

The Node.js playground gives you a Linux machine with Node.js, npm and corepack for yarn and pnpm, and VS Code in your browser with ESLint and Prettier. Start a project, install packages, run a server and try it from the terminal. You have root access, and the machine is deleted when the session ends.

Frequently asked questions

Is there a free online Node.js environment?

Yes. With a free account you open a machine with Node.js and VS Code in your browser, for 60-minute sessions. When one ends you can start another straight away.

Are yarn and pnpm available?

Yes, through corepack. Run corepack enable and both are ready beside npm.

Do I need Node.js on my computer?

No. Node.js and VS Code run on the machine you open; all you need is a browser.

Is my project saved?

No. The machine is deleted when the session ends. Push the project to a Git repository before the time runs out.
