Code Playground
Write HTML, CSS, and JavaScript and see it render live in a sandboxed preview — a quick CodePen-style scratchpad, right in your browser.
Runs in a sandboxed frame in your browser — your code isn’t uploaded, and it can’t touch this page. Work is auto-saved locally.
Frequently asked questions
Does my code run safely?+
Yes — it runs in a sandboxed iframe that can execute scripts but cannot access this page, your cookies, or the network origin. Nothing is uploaded.
Is my work saved?+
Your HTML, CSS, and JS are auto-saved in your browser's local storage, so they're still there when you come back. Use Reset to start fresh.
What's it good for?+
Quickly prototyping a component, testing a snippet, debugging a layout, or sharing a small demo — without setting up a project.
