Safari for Developers
Safari is the best way to see the sites on iPhone, iPad, and Mac. Thanks to blazing-fast performance and industry-leading energy efficiency, hundreds of millions of users enjoy exploring the web with Safari. Take advantage of powerful new features, advanced developer tools, and cutting edge technologies in Safari to deliver the best-in class websites and apps.
Apple Pay on the Web
Give customers an easy and secure way to make purchases in Safari 10 or later. Apple Pay allows customers to quickly pay without entering payment, shipping, or contact information on supported websites from their Mac, iPhone, or iPad. Because card numbers aren’t used and every transaction is confirmed with a fingerprint or passcode, Apple Pay is more secure than accepting credit and debit cards.

Safari Extensions on the Mac App Store
The new Extensions category on the Mac App Store showcases Safari extensions, with editorial spotlights and top charts to help users discover and download great extensions from the developer community. Use Xcode to develop your extensions, with the option to get started using App Extension templates, and implement new capabilities using powerful native APIs and familiar web technologies. Xcode 12 supports the popular WebExtension API and includes a porting tool to make it easy to bring your extensions to Safari. And if you’ve already developed an app, you can give users access to your app’s functionality and content, right in Safari.
HTML5 and Legacy Plug-ins on macOS
To deliver faster load times, better battery life, and stronger security, Safari is optimized for HTML5, and will load this content whenever it is available. For websites that use proprietary formats, Safari supports the use of plug-ins such as Flash. In Safari 10, plug-ins are supported for websites where HTML5 is unavailable and may be enabled by users for each individual website. Users can choose to enable plug-ins for one session or every time they visit a specific website. For frequently-visited websites, enabled plug-ins will remain active. For infrequently-visited websites, plug-ins will be disabled.
Content Blockers on macOS
If you previously created Content Blockers for Safari on iOS, you can easily bring them to macOS. You’ll be able to distribute and sell Content Blockers through the Mac App Store. Just like the new Safari Extensions, Xcode makes it easy to create Content Blockers using App Extension templates.
Autoplay and Inline Video on iOS
To help users easily discover your video content, you can now autoplay videos and play them inline with other content on your webpages on all iOS devices. Safari supports autoplay on iOS devices for videos without sound, keeping down the number of distractions on the web.
Split View in Safari on iPad
Users can now view two websites at the same time on their iPad using Split View. Responsive Design Mode makes it easy to see how your websites will render in this view — just tap the iPad preview until it turns into a Split View.
