Script Editor & Code Scanner – Live HTML, CSS & JS Preview (PC & Mobile)

Slim ABBAR and Hafedh KHAYATI built this editor while working on the Toolkit Rapid Free pages themselves — constantly needing to paste, preview and debug HTML snippets without opening a full IDE. The Script Editor & Code Scanner is the result: a free browser workspace to analyze, test, clean and understand complete web pages. Paste a full HTML document, preview it live and automatically extract CSS, JS and HTML into clean separated blocks.

Unlike basic editors, this tool is a true development laboratory directly in your browser. Visualize your project on desktop and mobile screen simultaneously, test responsiveness, layout and interactions — without installing any software.

Everything runs 100% locally in your browser. No uploads, no server processing, no data collection. Safe for private projects, templates, learning and debugging. If you find a bug or want a feature, write to us — we personally read every message.

Last updated: March 2026 · Everything on this page is designed for practical browser-based use with privacy in mind.

The built-in Quick Report scanner generates a technical audit: number of stylesheets, inline styles, external scripts and images — perfect to detect heavy resources or unnecessary dependencies.

Ideal for:

  • Learning HTML, CSS and JavaScript by analyzing real examples.
  • Cleaning and optimizing Blogger templates and landing pages.
  • Testing and debugging layouts before publishing.
  • Extracting reusable components from existing projects.
  • Validating responsive design on desktop and mobile viewports.
Quick start: paste your full page code into the Script Zone, preview it instantly in PC or Mobile mode, then extract the clean HTML, CSS and JavaScript blocks and use the Quick Report to spot heavy resources or unnecessary dependencies.

Privacy Note: All code is processed locally in your browser. Nothing is uploaded or stored on any server.

Why this tool exists: It was created to simplify real daily development tasks. Instead of switching between multiple apps, you can test, preview and clean code in one place instantly.

Limit: Some complex scripts, external APIs or advanced frameworks may not run fully in preview due to browser security limits.
