Apple Launches 'Safari Technology Preview' Browser for Web Developers
Apple today launched Safari Technology Preview, a new version of its web browser aimed specifically at developers. Safari Technology Preview is aimed at giving developers a way to access new web technologies Apple is planning to implement in iOS and OS X, offering an early look at new developer tools, layout technologies, visual effects, and more.
According to TechCrunch, Apple's goal with Safari Technology Preview is to gather feedback from developers on its browser development ahead of launch through a method that's more easily accessible than WebKit.
Safari Technology Preview can be run side-by-side with the existing Safari browser, and it's able to be set as the default browser on a machine. It includes local data stores for history, bookmarks, cookies, and cache, and it supports syncing of browsing history and bookmarks over iCloud. Visually, the Safari Technology Preview icon is designed to resemble the Safari icon, but it is purple in color instead of blue.
