When you download Google Chrome or Mozilla Firefox on your iPhone, you might expect the same browsing engine that powers those browsers on desktop and Android. Instead, you get Safari wearing a different skin. Apple mandates that every browser on iOS use its WebKit rendering engine, effectively eliminating browser competition on the world's most profitable mobile platform. This policy has consequences far beyond user preference.
How WebKit Restrictions Harm the Open Web

WebKit consistently trails Google's Blink and Mozilla's Gecko engines in supporting modern web standards, particularly progressive web apps (PWAs). PWAs can function like native apps with offline support, push notifications, and hardware access. A fully capable PWA ecosystem would undermine the App Store's role as the sole distribution channel for iOS applications. By restricting browser engines, Apple ensures that web apps remain second-class citizens on iPhone, protecting its App Store revenue stream. The Open Web Advocacy group documented over 100 web features supported by Chrome and Firefox on other platforms but unavailable on iOS due to WebKit limitations.

This arrangement gives Apple a massive financial incentive to keep Safari dominant and to prevent competing browsers with different default search agreements from gaining traction on iOS. The DOJ's antitrust case against Google identified this payment as a central mechanism for maintaining Google's search monopoly, making Apple a co-beneficiary of the arrangement.

The EU's Digital Markets Act required Apple to allow alternative browser engines in Europe. Mozilla has begun developing a true Gecko-based Firefox for iOS in the EU, and Google is working on a Blink-powered Chrome. Early benchmarks show significant performance improvements. For users outside Europe, the wait continues as similar legislation moves slowly through other jurisdictions. The browser engine restriction remains one of the least visible but most consequential elements of Apple's platform control.
