Bringing Kotlin to the Web

Developers often rewrite their apps in JavaScript to reach users on various platforms.
WebAssembly GC allows running cross-platform code written in supported languages with near-native performance inside all major browsers.
Experimental support for WebAssembly GC for Kotlin is now available, unlocking new code sharing opportunities for Android and Web developers.
Kotlin Multiplatform frameworks from JetBrains help developers share code between Android and iOS apps.
Bringing modern mobile languages like Kotlin to the Web required solving challenging technical problems.
WebAssembly allows combining the productivity of cross-platform development, the performance of native mobile apps, and the openness of the web.

Pulling it off

Multi-language garbage collection and JavaScript interoperability were challenging technical problems that needed to be solved to bring Kotlin to the Web.
Technical details about this innovative work will be shared on the V8 Blog soon.

WebAssembly allows developers to work on the Web and native experiences together with the productivity of cross-platform development and the performance of native mobile apps.
The openness of the web allows developers to reach new users easily, with no app stores getting in the way and no revenue split affecting profitability.
