Source Sniffer is a free Chrome add-on developed by kardagan that allows you to search for specific text or code within the HTML source code of a website while you navigate. With this tool, you can program your own sniffers and receive alerts whenever they find something.

Whether you want to remove an old HTML block that is no longer needed and is slowing down your page, or you want to add code to all the pages of your website for SEO purposes, Source Sniffer makes it easy. Instead of manually searching through the source code page by page, you can simply program a sniffer to search for the desired text or code and be alerted if it exists on any of your pages.

Source Sniffer is a valuable tool for website owners and developers who need to quickly search for specific elements within the source code of their websites. It simplifies the process and saves time by automating the search and alert process.
