The Kwebby Get Source Code of Webpage tool fetches the raw HTML of any URL so you can read it, copy it or save it as a file. Enter an address, click Fetch, and the page source appears in a scrollable box with its status, size and final URL. This guide shows what the tool returns, where it stops, and how it compares with View Page Source in your browser. You can find more checks in our Free Developer Tools.
Key Takeaways
- The Kwebby tool fetches a URL on the server and shows the raw HTML response, with Status, Size and the final URL.
- You can copy the full source or download it as
source.html. The code box itself shows only the first 50,000 characters. - The tool shows the HTML before JavaScript runs. Content that scripts add later is not in this source.
- It follows redirects and lists each hop above the code, so you get the source of the final page.
- A search box filters the source to matching lines with line numbers.
- Google queues pages for rendering with headless Chromium and uses the rendered HTML to index them, so raw source is only the first step of what Google sees.
- The tool is free and needs no account.
What Is the Kwebby Get Source Code of Webpage Tool?
The Kwebby Get Source Code of Webpage tool is a free online source code viewer that shows the raw HTML a web server sends for a URL. It makes the request from our server with a desktop browser user agent, so you see the response without opening developer tools. Servers can send different HTML to different user agents, so the source can differ from what a phone or a search crawler receives.
Use it when you want to read a page's head tags, find structured data, check a script tag or save a copy of the HTML. The source is the document a browser starts from, before it builds the page you see.
Key Features and How It Works
The tool has a URL box, a Fetch button and a result area with four parts: a status bar, two buttons, a search box and a code box.
Status, Size and Final URL
Above the code, a bar shows the Status code, the Size of the response in bytes or KB, and the final URL of the request. On 4 October 2026, https://example.com returned status 200 and a size of 577 B.
Copy and Download
The Copy button puts the full source on your clipboard. The Download .html button saves it as a file named source.html. Both use the whole response, even when the code box is cut short.
A Scrollable Code Box
The box shows the first 50,000 characters of the response and scrolls inside a fixed height. A longer page ends with the note "(truncated for display, download or search for the full source)".
Search the Source
Type a word such as canonical, noindex or gtag into the search box, and the code box switches to the matching lines from the full source, each with its line number. The tool shows up to 200 matching lines. Clear the box to see the source again.
Raw HTML, Not the Rendered Page
The tool shows the HTML as the server sent it, before any script runs. If a page builds its content with JavaScript, that content will not appear here. To see it, open your browser's Inspect panel on the live page.
Redirects Are Followed
If your address redirects, the tool follows up to 10 redirects and shows the source of the final page. A line above the code lists each hop with its status code, and the status bar shows the final URL. To see the headers of each hop, use Get HTTP Headers.
Blocked and Error Pages
Some sites block automated requests. When the server answers 401, 403, 429 or 503, an amber note says the source is probably a block, login or error page and not the page a normal visitor sees. The tool keeps up to 5 MB of source.
Raw Source Versus What Google Sees
The raw source is the first thing Google fetches, but it is not the last. Google's JavaScript SEO guide says Googlebot crawls the URL, parses the HTML for links, and queues pages with a 200 status for rendering. A headless Chromium then renders the page and runs the JavaScript. Google also uses the rendered HTML to index the page.
Google adds that parsing the HTML response works well for classic or server-side rendered pages, where the response holds all the content. So if your key text and links appear in this tool's output, they are in the response from the first request. If they only appear in your browser, a script adds them later.
How to View Source Code in Your Browser
You can also view a page's source with one shortcut in most desktop browsers. BrowserStack's guide lists these:
- Chrome, Windows or Linux: Ctrl+U. On a Mac, press Cmd+Option+U.
- Firefox, Windows or Linux: Ctrl+U. On a Mac, press Cmd+U.
- Edge: Ctrl+U.
- Safari: Option+Command+U, after you turn on developer features.
- Any browser: right-click the page and choose View Page Source.
Browser source works on pages you can open yourself, including ones behind a login. The Kwebby tool is useful when you want a file you can download, a copy from a clean server request, or a quick look without opening a browser tab for the page.
How to Use the Get Source Code of Webpage Tool
- Open the tool and click the box that reads
https://example.com. - Type or paste the full address of the page.
- Click Fetch, or press Enter. The button reads "Fetching..." while the tool shows "Fetching page source...".
- Read the Status, Size and final URL above the code.
- Scroll the code box, and use your browser's find command to search the text.
- Click Copy for the full source, or Download .html to save
source.html.
If a red message such as "Unable to resolve hostname" appears, check the address for typos.
Best Practices for Reading Page Source
Start With the Head
Scroll to the <head> first. Look for the title, meta description, robots tag, canonical link and Open Graph tags. For a readable report of those tags, run the Meta Tags Analyzer.
Look for Structured Data
Search the text for application/ld+json to find JSON-LD blocks. Check that each block matches what the page shows.
Compare Raw and Rendered Pages
Open the page in your browser, inspect an element, and look for the same text in the tool's output. If the text is missing from the source, a script adds it, and Google needs to render the page to see it.
Enter the Final Address
If you see a 301 or 302 status, use the address the browser ends on, including the www prefix and https if the site uses them.
Respect the Code You Read
Reading source to learn is normal practice. Copying a site's code without permission is another matter, and SeoChecker's source viewer page cautions that doing so may infringe the owner's copyright. Write your own code, or use licensed themes and libraries.
Common Use Cases
- Tag checks. Confirm the title, meta description, canonical and robots tags are in the HTML.
- Structured data checks. Find JSON-LD, Microdata or RDFa markup.
- Script audits. Check that analytics or tag manager snippets are in the source.
- Link checks. Read the raw links, then count them with the Website Links Count Checker.
- Theme research. Look for
wp-content/themesto find a WordPress theme, or use the WordPress Theme Detector. - Offline copies. Save a page's HTML as
source.htmlfor later review.

Frequently Asked Questions (FAQs)
What is the source code of a webpage?
The source code of a webpage is the HTML document a web server sends to the browser. It holds the page structure, meta tags, links, inline styles and scripts, and references to other files.
How do I view the source code of a website?
Enter the address in the Kwebby tool and click Fetch. In most desktop browsers you can also press Ctrl+U, or Cmd+Option+U in Chrome on a Mac, to open View Page Source.
Can I see JavaScript-rendered content?
No. The tool shows the raw HTML the server sends, before any JavaScript runs. Content that scripts add later appears in the browser's Inspect panel, not in this source.
What happens when the URL redirects?
The tool follows the redirects and shows the source of the final page. A line above the code lists each redirect hop, and the status bar shows the final URL.
Why is the code cut off in the box?
The code box shows the first 50,000 characters and then a note that the display was truncated. The Copy button and the Download .html button still use the full source.
Is the Kwebby source code viewer free?
Yes. The tool is free to use and needs no account.
Final Thoughts
Page source is the quickest way to check what a server really sends. Fetch the page you care about, read the head tags, find the structured data and note anything that your browser adds later. Then check the response headers with Get HTTP Headers to see the full picture.
