Safari app extensions leverage web technologies and native code to extend the web-browsing experience in Safari

Safari app extensions leverage web technologies and native code to extend the web-browsing experience in Safari.

Safari app extensions are available in OS X 10.12 and later and in OS X 10.11.5 when Safari 10 is installed. Using a Safari app extension, you can add new functionality to Safari, read and modify web page content, and communicate with your native application to integrate its content into Safari or send web data to your app.

Safari app extensions are written using a combination of JavaScript, CSS, and native code written in Objective-C or Swift. Safari app extensions are built on the standard app extension model.
