Compact tab bar

In the compact tab bar view, the browser interface yields to the content. Safari blends the tab bar into each website by matching its background color. As a web designer or developer, you can choose the color and code it into your HTML. The entire interface is on one line, and elements naturally appear when needed, making your content feel more expansive as each web page or web app extends to all four edges of the window.

Apple Pay on the Web

Provide an easy and secure way to make purchases in Safari 10 or later.

Because card numbers aren’t used and each transaction is confirmed with a fingerprint or passcode, Apple Pay is more secure than accepting credit and debit cards.

Web Push in Safari

Send notifications to people who use your website or web app in Safari 16 on macOS 13 — even when Safari isn’t running. Fully interoperable, Web Push’s standards-based implementation relies on the Push API, Notification API, and Service Workers. If you’ve already coded Web Push using industry best practices, it will automatically work on Safari. And you don’t need to be an Apple Developer Program member to implement this feature.
