Link Highlighter Internal

Link Highlighter (Internal vs External) is a lightweight Chrome extension that helps users visually identify internal and external links on any web page.

With a single click, the extension highlights links that point to the same domain as the current page and distinguishes them from links that lead to external websites. This makes it easier to understand link structure, navigation paths, and outbound references without inspecting page source code.

The extension runs only on the active tab when the user interacts with it. All processing is performed locally in the browser. No user data is collected, stored, transmitted, or shared. The extension does not track browsing activity and does not require access to external servers.

Link Highlighter is useful for website owners, SEO specialists, developers, content editors, and anyone who wants a quick and simple way to analyze link types directly on a page. Its minimal design keeps the interface clean and focused while providing immediate visual feedback.
