kotlin2.4.21

Compile Kotlin source code from the command line and turn it into applications for several kinds of devices and environments. Kotlin is a statically typed language, so value types participate directly in source code and the development process. Its main purpose is to help developers share code across platforms instead of maintaining entirely separate implementations.

JetBrains’ Kotlin supports backend, mobile, web, and desktop application development. Concise syntax makes programs less verbose, while null safety helps catch a major class of errors during development. The language also includes capabilities aimed at AI-assisted development, including open benchmarks and tooling designed for coding agents.

Kotlin suits professional software developers building modern multiplatform applications, as well as teams that need common code across different targets. Its command-line compiler is useful in development workflows where source files must be compiled directly or incorporated into broader build processes.

The current release is 2.4.21, published as open-source software for Linux on x86_64 (amd64) systems. Using it requires Linux with snapd, and the Linux build is provided by JetBrains.
