User-Agent Viewer

View and copy your browser user-agent string in a clean popup.

User-Agent Viewer is a lightweight Chrome extension that allows users to quickly view their browser’s user-agent string in a clean and modern popup. When the extension is opened, it displays the current browser user-agent in a readable format. Users can easily copy the user-agent string to the clipboard or refresh the view if needed. This is useful for debugging, testing, development, or sharing browser information with support teams. The extension runs entirely inside the popup and does not interact with web pages. All functionality works locally in the browser. No data is collected, stored, transmitted, or shared with any third parties, and no network access is used. User-Agent Viewer requires no special permissions and respects user privacy by design. It is suitable for developers, testers, and anyone who needs a quick and reliable way to view and copy their browser’s user-agent string.
