Browser playground limits
• Code runs in a sandboxed browser preview, without Node.js, a backend, or private environment variables.
• The Console prompt can inspect browser globals and the rendered DOM, but not variables scoped inside ES modules or component state.
• Download the project when you need build plugins, server APIs, native modules, or a production dependency workflow.
How to use the HTML playground
Edit the JavaScript, HTML and CSS tabs — the live preview updates automatically.
Switch the target or styling from the toolbar, then open the tabs you need.
Use the console for logs and errors, and Format to tidy the active tab.
Share the complete snippet or download it as a single HTML file.

Frequently asked questions
Is the HTML playground free?
Yes. The HTML playground is completely free with no sign-up — write, run and share HTML code in your browser.
Do I need to install anything to run HTML online?
No. The live preview runs in your browser, and the single-file HTML export does not require a project setup.
Can I share or export my HTML code?
Yes. Share creates a link to your snippet. Download exports a single HTML file you can open in a browser.
Does the editor support autocomplete and live preview?
It does — a Monaco-powered editor with autocomplete and formatting, a live preview that updates as you type, and a console for logs and errors.
