How to view a web page's source code online

1. Enter the page URL

   Paste the public web address into the URL field. The https:// prefix is optional — the tool adds it if you omit it. Private IPs and localhost are blocked.

2. Fetch the source

   Press the button. The HTML is fetched server-side and displayed directly in the viewer. This is the raw server response before JavaScript runs — not the post-execution DOM. Single-page apps may show only a minimal HTML shell.

3. Read the source inline

   The source is displayed in a scrollable code block. Use your browser's built-in Ctrl+F (or Cmd+F) to search for specific tags, meta content, structured data blocks, or script URLs within the fetched HTML.

4. Save as a file if needed

   Use the accompanying download option to save the source as a .txt file for offline inspection. This viewer and the source-code-downloader tool fetch from the same endpoint — the viewer adds inline display while the downloader triggers a file save directly.
