What is this code editor?

This is a free, browser-based HTML, CSS, and JavaScript playground built by HixCode. It uses CodeMirror 5 for syntax highlighting, bracket matching, and a professional editor experience — no installation required. Your code is automatically saved in your browser so you never lose your work between page refreshes.

Perfect for learning web development, testing a CSS animation, prototyping a UI component, or showing a client a quick demo. The live preview updates as you type (debounced at 300 ms), the console panel captures console.log() output and errors, and the Download button exports everything as a standalone .html file.

How to use the online code editor

  1. Write your markup in the HTML tab.
  2. Switch to the CSS tab to style it, and the JS tab to add interactivity.
  3. Watch the Live Preview update as you type, and check the Console panel for console.log() output and errors.
  4. Click Copy to copy the current tab, or Download to save everything as one .html file.
  5. Click Reset any time to start again from the starter template.

Frequently asked questions

01Is the HixCode code editor free?

Yes. The editor is completely free with no sign-up, no account, and no usage limits. Open the page and start writing HTML, CSS, and JavaScript immediately.

02Is my code saved?

Your code is saved automatically in your browser's localStorage every time you type, so it survives page refreshes and browser restarts on the same device. Nothing is uploaded to a server. Clearing your browser data or switching devices will remove it, so use Download to keep a permanent copy.

03How do I download my code?

Click the Download button above the editor. Your HTML, CSS, and JavaScript are combined into a single standalone hixcode-project.html file that opens in any browser.

04Can I use external libraries like Tailwind CSS, Bootstrap, or jQuery?

Yes. Add a <script src="..."> or <link rel="stylesheet" href="..."> tag from a CDN such as cdnjs or jsDelivr in the HTML tab, and the library loads in the live preview.

05How do I see console.log() output?

Use console.log(), console.warn(), or console.error() in the JS tab. Output appears in the Console panel under the live preview, along with any JavaScript errors and their line numbers.

06Does it work on mobile?

Yes, the editor runs in any modern browser on desktop, tablet, or phone. A larger screen is more comfortable for editing because the code and the live preview sit side by side.

07Is my code private?

Yes. Your code runs entirely in your own browser inside a sandboxed preview frame. HixCode does not receive, store, or see the code you write.
