Using alternative browser engines in Japan
In iOS 26.2 and later, browser engines other than WebKit can be used in two types of apps for users in Japan: Dedicated browser apps that provide a full web browser experience, and apps from browser engine stewards that provide in-app browsing experiences using an embedded browser engine.
Apple will provide authorized developers access to technologies within the system that enable critical functionality and help them offer high-performance modern browser engines. These technologies include just-in-time compilation, multiprocess support, and more.
However, as browser engines are constantly exposed to untrusted and potentially malicious content and have visibility of sensitive user data, they are one of the most common attack vectors for bad actors. To help keep users safe online, Apple will only authorize developers to implement alternative browser engines after meeting specific criteria and who commit to a number of ongoing privacy and security requirements, including timely security updates to address emerging threats and vulnerabilities.
