Source Code Viewer is a Chrome extension that lets you view the complete source code of any website in a clear, organized tabbed interface. It extracts the full HTML document along with all external and inline CSS and JavaScript files, displaying each in its own labeled tab. Key features include: Viewing the entire HTML source (documentElement.outerHTML). Fetching and showing each external CSS and JS file in separate tabs, including inline styles and scripts. One-click copy buttons for easy copying of any code block. A loading indicator and user-friendly error messages if files fail to load. Ability to download the entire source code as a ZIP file. The extension requires permissions to access the active tab, inject scripts to gather source code, and fetch external resources. You can install it, visit any webpage, click the extension icon, and instantly browse or download the full source code for offline use or analysis.
