Featured web technologies

Safari Extensions

Safari extensions are a powerful way to add new features to Safari. They are built in Xcode with web technologies, such as HTML5, CSS3, and JavaScript and powerful native APIs. Now you can distribute and sell them through the App Store on Mac, iPhone and iPad.

Universal links

Seamlessly link to content within your app or on your website in iOS, iPadOS, and macOS. With universal links, you can always give users the most integrated mobile experience, even when your app isn’t installed on their device.

Smart App Banners

Make it easy for people to discover and download your app using iOS, iPadOS, and macOS. With Safari Smart App Banners, you can display a banner that provides a direct link to your app on the App Store, or opens the app if the user already has it installed. Smart App Banners integrate seamlessly and are easy to implement.

HTTP Live Streaming (HLS)

Deliver streaming media to apps on iOS and iPadOS or HTML5-based websites using an ordinary web server.

Safari iCloud Keychain

Easily create more secure logins for users in iOS 15, iPadOS 15, and macOS Monterey or later using iCloud Keychain verification codes. Take advantage of verification codes, AutoFill, iCloud Keychain sync, and two-tap setup to simplify the multistep sign-in process.

Safari Push Notifications

Use the Apple Push Notifications Service to send notifications to your website vistors, right on their Mac desktop — even when Safari isn’t running. These notifications display your website icon and notification text, which people can click to go right to your website.


Introduced by Apple, WebKit is the most advanced rendering engine, drawing the web pages in Safari on iOS, iPadOS, and macOS.


Write automated tests to exercise web content in Safari to ensure a good user experience, and run those same tests against other browsers with a WebDriver-compliant driver.
