Kotlin is a modern programming language developed by JetBrains, designed to interoperate with Java and run on the Java Virtual Machine (JVM). With features like null safety, type inference, and extension functions, Kotlin offers a concise and expressive syntax for building robust and scalable applications. Developers can learn Kotlin's language features, explore its ecosystem of libraries and frameworks, and leverage Kotlin for developing Android apps, server-side applications, and multi-platform projects.

The Kotlin Foundation is participating in Google Summer of Code (GSoC) 2026, offering students and eligible contributors the chance to work on real Kotlin open-source projects with mentorship from experienced engineers. Four projects are available this year: a Kotlin Compiler Fuzzer, Swift-to-Kotlin interop proof of concept, tail call support in Kotlin/Wasm, and a Kotlin Education landscape report. The contributor application period runs until March 31, with coding starting May 25. Non-students can also explore the Kotlin Ecosystem Mentorship Program.
