The State of Kotlin in 2026 Report
The State of Kotlin in 2026 Report
In 2026, Kotlin turned fifteen. Over those fifteen years, Kotlin has built a mature ecosystem, been adopted by companies around the world, and established a large and active developer community.
Fifteen years is long enough to understand which technology trends lasted and which didn’t. This report looks back at Kotlin’s first fifteen years to see what they reveal about how the language matured, while answering questions like: “Is Kotlin here to stay?”, “Can Kotlin scale across platforms?”, and “How does Kotlin fit into the AI era?”
Today, developers worldwide use Kotlin across a diverse range of applications, including mobile, backend, and multiplatform. The language is also finding its place in the rapidly evolving AI space, where Kotlin’s strengths, like static typing, null safety, and coroutines, take on new relevance. Kotlin is actively participating in the shift toward AI-assisted development: Among surveyed Kotlin developers, 93% use at least one AI coding tool, while 81% already use or are likely to try AI coding agents. An equal share – 81% – say that AI-generated Kotlin code is fully correct or requires only minor fixes.
The State of Kotlin in 2026 report combines data from JetBrains research with independent industry data and real-world adoption evidence. Some findings confirmed what we expected; others challenged some familiar assumptions. While the language remains deeply established in Android development, more than half of Kotlin developers now report working on backend projects, highlighting how far its usage has expanded beyond mobile.
Together, these findings point to a broader story: Kotlin’s evolution isn’t just about growth, but about how diverse its usage has become, spanning backend, multiplatform, AI-assisted development, and more. At the same time, the developer community itself has grown more experienced.
