See how your site behaves in various browsers by tweaking the user agent. NOTE: Websites may still use fingerprinting techniques to determine what browser you are using. Unguent does not actually change the browser engine used by Safari. The user agent tells a website what browser (including the version) you are currently using. By detecting the user agent, websites can change their behavior appropriately (such as by disabling features where not supported). Features - Choose from a set of preset user agents, or add and manage your own presets - Set a user agent as a global user agent, or set user agents per site - Update preset user agents Unagent does not collect any data, and only rewrites the User-Agent header where necessary.
