See the Blueprint Behind Every Web Page.
What you see in the browser is the final render. What search engines and developers see first is the HTML source code—the foundational instructions, hidden tags, and structured data that dictate indexing, accessibility, and performance. Auditing this code is the first step in diagnosing SEO issues, security flaws, and technical debt.
Inspect Instantly with Our Free HTML Source Code Viewer.
Go beyond "View Source." Our tool fetches the raw, unrendered HTML of any public webpage in real-time, presenting it in a clean, readable format. Analyze meta tags, uncover hidden content, verify script placement, and check for structured data without any browser plugins or developer tools.
Why Analyzing Source Code is a Foundational Audit Skill:
Audit On-Page SEO Directly: Verify the existence and correctness of critical tags (title, meta description, canonical, h1-h6, alt text) that directly influence search rankings.
Uncover Hidden or Cloaked Content: Detect content that is present in the HTML but hidden from users via CSS (a potential spam signal), or identify lazy-loaded elements that search engines may not see.
Check Technical Implementation: Validate the placement of scripts (are render-blocking scripts in the <head>?), assess schema markup, and identify unminified code that slows page speed.
Diagnose Crawling & Indexing Issues: Find noindex directives, robots meta tags, or incorrect canonical links that might be preventing pages from being indexed as expected.
From Raw Code to Actionable Insights.
Our viewer is designed for analysis, not just display:
Clean, Formatted Output: The HTML is presented with syntax highlighting and proper indentation for easy reading.
Line Numbering: Reference specific lines when reporting issues or collaborating with developers.
Find Functionality: Quickly search the source for specific tags, keywords, or code snippets.
Character Encoding Detection: Shows the declared encoding, crucial for international SEO and proper rendering.
Link & Resource Extraction: Easily identify all external stylesheets, scripts, and images referenced in the code.
Your Technical SEO & Development Audit Protocol:
Enter the Target URL: Load the page you need to audit (your page or a competitor's).
Fetch the Source Code: Retrieve the latest, uncached version of the page's HTML.
Perform a Structured Scan:
Head Section: Check <title>, <meta> tags, and <link> relationships.
Body Structure: Review heading hierarchy (<h1> to <h6>), image alt attributes, and semantic HTML5 elements.
Scripts & Styles: Note the size and placement of CSS and JavaScript files.
Structured Data: Look for JSON-LD, Microdata, or RDFa markup.
Document Findings & Act: Note discrepancies, missing elements, or inefficiencies and create a prioritized fix list.
Critical For:
Technical SEO Specialists: Perform in-depth on-page technical audits beyond surface-level tools.
Web Developers & Front-End Engineers: Quickly inspect a live site's markup for debugging or learning purposes.
Digital Forensic & Security Researchers: Analyze page construction for hidden elements or malicious code injections.
Content Strategists: Verify that the intended SEO elements are actually present in the published page's code.
Students & Learners: Understand how real-world websites are built by examining their underlying structure.
Free, Direct, and Unfiltered.
Access to a website's foundational code should be straightforward. This viewer is 100% free, provides the exact HTML as delivered by the server, and respects robots.txt directives. The URLs you analyze are used solely for the fetch request and are not stored.
Look Beyond the Render. Understand the Foundation.
