About the Free Live Code Editor

The Live Code Editor is a lightweight HTML, CSS, and JavaScript playground that runs entirely in your browser. Write code in three synchronized editors and watch the output update in a live preview iframe — no server, no setup, no account.

Key Features

Three-Panel Editor: HTML, CSS, and JavaScript paneled side-by-side with syntax highlighting and line numbers.
Live Preview: The iframe output refreshes automatically as you type (and instantly when you hit Run).
Error Awareness: Script errors are surfaced inside the preview so you always know what broke.
Auto-Save: Your code is persisted to localStorage and restored on the next visit.
One-Click Export: Download your whole page as a single, self-contained .html file.

Why Keep a Scratchpad Open?

A live code sandbox is the fastest way to experiment with CSS animations, test a JS snippet, or prototype a layout without creating a project. Because everything is saved locally, you can close the tab and pick up exactly where you left off.

How It Works

The editor opens with a demo template so you can see how panels and preview connect.
Edit any of the three panels — the preview rerenders on the fly.
Hit Run to force a refresh at any moment.
Use Download .html to save a standalone file.
Use Reset Template to restore the starter example.
