Source Code Viewer

Source Code Viewer

Inspect formatted HTML source code, DOM structure, stylesheets, and scripts of any public URL with clean syntax highlighting and line numbers.

About Source Code Viewer

The Source Code Viewer provides a fast, sandboxed environment to inspect the raw HTML markup, inline styles, client-side scripts, and structured data of any public URL. Built for software engineers, technical SEOs, and DevOps operators, this utility fetches the exact server response delivered to user agents, enabling rapid inspection without opening browser developer tools or downloading page assets.

Use the source viewer to audit OpenGraph meta tags, canonical link headers, Schema.org JSON-LD microdata, and external asset dependencies. The built-in syntax highlighter makes reading minified HTML, SVG assets, and embedded JavaScript templates effortless while debugging rendering anomalies or checking third-party tracking scripts.

How it works

What is the difference between View Source and Inspect Element?

View Source retrieves the original HTML document returned directly by the web server before JavaScript execution, while browser Inspect Element displays the live, rendered DOM tree after client-side scripts have run.

Can I use this tool to inspect structured data and SEO tags?

Yes, you can easily verify meta tags, OpenGraph properties, Twitter cards, and Schema.org JSON-LD payloads to ensure technical SEO compliance.

Does the source code viewer execute client-side JavaScript?

No, the tool operates in a sandboxed mode to safely fetch raw server markup without triggering client-side scripts, trackers, or cookies on your device.
