Safari is a web browser developed by Apple. It is built into several of Apple's operating systems, including macOS, iOS, iPadOS, and visionOS, and uses Apple's open-source browser engine WebKit, which was derived from KHTML.

Safari was introduced in Mac OS X Panther in January 2003. It has been included with the iPhone since the first-generation iPhone in 2007. At that time, Safari was the fastest browser on the Mac. Between 2007 and 2012, Apple maintained a Windows version, but abandoned it due to low market share. In 2010, Safari 5 introduced a reader mode, extensions, and developer tools. Safari 11, released in 2017, added Intelligent Tracking Prevention, which uses artificial intelligence to block web tracking. Safari 13 added support for Apple Pay, and authentication with FIDO2 security keys. Its interface was redesigned in Safari 15.
