Roughly speaking, yes. Alternative browsers for iOS can offer a different UI or a different way of handling bookmarks, but they're always powered by the same rendering engine and JavaScript engine that Safari uses. Apple even seems to forbid extending the capabilities of WebKit and JavaScript Core, presumably you wouldn't be permitted to add support for additional video codecs for instance. [0] The only exception is Opera Mini, which is a frontend for Opera's cloud-based HTML rendering infrastructure, [1] so it doesn't count as a browser under Apple's rules. (Opera Mini for iOS has been discontinued.) [0] https://developer.apple.com/app-store/review/guidelines/#third-party-software https://developer.apple.com/app-store/review/guidelines/#thi...
