Safari

Safari is Apple's browser across Mac, iPhone, iPad and Vision, with Intelligent Tracking Prevention, Private Browsing that locks windows, customisation options and battery life optimisation, and Apple claims it is the world's fastest browser.

Battery life optimisation is the argument that carries the most weight in practice and it is one only Apple can make properly. Controlling the browser, the operating system and the silicon means Safari can be tuned against the specific hardware it runs on, which is why a laptop browsing in Safari genuinely lasts longer than the same laptop browsing in Chrome.

Intelligent Tracking Prevention was the change that reshaped the advertising industry more than any regulation did, because a default-on browser protection reaches everyone rather than the small share who would configure it, and Apple's willingness to ship it reflects that it does not sell advertising in the way its main rival does.

Safari's position on iOS is the part worth understanding before treating it as one browser among many: for most of its history every browser on iPhone rendered pages using Safari's engine, so what Safari supports has determined what web applications can do on the platform. Safari is free and included with Apple operating systems.
