See how your site behaves in various browsers by tweaking the user agent. The user agent tells a website which browser and device you're using, and sites use it to decide what to show you. Make Safari present like Chrome, Firefox, Edge, a game console, or a search engine crawler, so you can see how a site behaves in other browsers. Presets - Built-in presets for browsers, apps, search engines, AI crawlers, game consoles, and other devices, including older browsers like Internet Explorer - Create your own presets - Fill in the device's current OS version in your own presets automatically - Update the built-in presets to the latest browser versions, and see where each user agent comes from Site Settings - Set a global user agent for all websites, or a different one for each site - Per-site settings take priority over the global setting - Choose a desktop, tablet, or mobile viewport to change how large a site is shown - Change the user agent for the current site or for all sites from the Unagent extension in Safari Websites may still be able to tell that you're using Safari, for example through browser fingerprinting. Unagent does not change the browser engine Safari uses.
