Safari

Safari is Apple's default Web browser for OS X and iOS-based devices.  

In addition to features common to most current browsers, Safari's features include:

• Nitro JavaScript engine, said to execute JS much faster than Internet Explorer or Firefox.
• RSS feed aggregator.
• Synchronization of passwords, bookmarks, history, tabs and Reading List through iCloud.
• A private browsing mode that doesn't save browsing history or related information.
• The ability to zoom in on Web page details.
• Custom style sheets.
• Integrated Quicktime multimedia player.
• The ability to archive or email a Web page.
• Support for VoiceOver, an application that describes Web page content and reads text aloud.
• Options for keyboard-only navigation.
• A thumbnail display of the user's most visited sites.
• Apple's Keychain identify management scheme for password management.
• Integration with Apple's iWeb software.

Safari was originally released in 2003. The operating system is based upon Apple's Webkit, an application framework based upon two open source frameworks: WebCore and JavascriptCore. The source code for the non-rendering portions of Safari are all available at OpenDarwin.org.

The iPhone  and iPod Touch run an adapted version of Safari.
