Apple Launches ‘Safari Technology Preview’ for Developers to Test New Features

Wednesday, Apple announced immediate availability of a brand new browser created specifically for web developers. Safari Technology Preview, as it’s called, resembles an ordinary Safari browser with a distinctively purple app icon in the dock. With Safari Technology Preview, web developers can get their hands on improvements to WebKit and other web technologies and optimize their web code before these technologies trickle down in future releases of iOS and OS X.

“Get a sneak peek at upcoming Safari web technologies in OS X and iOS, and easily experiment with these technologies in your websites and extensions,” writes Apple.

Within the preview, developers will find tools, the latest layout for technologies and visual effects, and more. Users that try out the preview will be able to provide input for how those tools and technologies are implemented within Safari, which Apple hopes will help the company improve the overall experience within the browser where it is available.

Here’s what you can expect from the preview, as articulated by Apple:
  • Preview the latest web technologies. Get a preview of the latest advances in Safari web technologies, including HTML, JavaScript, and CSS. Safari Technology Preview includes the most recent version of WebKit, the rendering engine that powers Safari.
  • Easy to update. You can update Safari Technology Preview right from the Mac App Store. Updates occur every few weeks and include the most recent additions and improvements to WebKit.
  • Access powerful developer tools. Use the latest version of the powerful Web Inspector and Responsive Design Mode to modify, debug, and optimize your websites.
  • Provide feedback. Use Bug Reporter to send feedback directly to Apple about issues and enhancement requests. Simply select Report an Issue from the Help menu in Safari Technology Preview.
  • Run side-by-side with Safari. Safari Technology Preview is a standalone app that works side-by-side with the current version of Safari, so you can continue to use and reference the current release.
  • Surf seamlessly with iCloud. Safari Technology Preview works with iCloud, so you can access your latest Safari Favorites, bookmarks, and Reading List.
  • Keep current. The WebKit blog keeps you up-to-date on the latest developments in HTML, JavaScript, and CSS.
It’s worth noting that while this preview is meant for developers, the risk-taking public out there that might be interested in checking this out can do so, too. You’ll need OS X 10.11.4 or later to try it out, though.
