Features

  • Share directly to social media platforms or copy the link for custom sharing
  • Interactive Annotation Mode: Click highlighted elements to add comments for AI or team collaboration
  • Smart Snippets: Wraps code in standard HTML/Head/Body tags and auto-injects Tailwind CSS or Bootstrap when selected
  • Import HTML from local files and export your work as custom-named HTML files (defaults to index.html)
  • One-click code formatting to keep your HTML clean and readable
  • Toggleable Dark and Light themes

How this tool works

  1. Write, paste, or import your HTML code into the editor.
  2. Click the 'Run' button to update the live preview on the right side.
  3. Use the Snippet tool to quickly test raw code-the tool will automatically add document wrappers and necessary CSS libraries (Tailwind/Bootstrap).
  4. Toggle 'Annotation Mode' and click any element in the preview to attach comments that won't break your site layout.
  5. Drag the divider to resize panes, or click 'New Tab' to inspect the clean preview using your browser's native developer tools.
  6. When finished, export your code as an HTML file or generate a password-protected URL to share with your team or an AI.
