A quick way to understand who this product may suit, where its limits matter, and which facts are most relevant before you compare alternatives.
Java and Kotlin developers who want code analysis, refactoring, debugging, build-tool support, and framework tooling in a desktop IDE.
Teams seeking a browser-hosted development environment or primarily focused on a non-JVM language may prefer another tool or a more specialized JetBrains IDE, and should evaluate alternatives such as Eclipse or Visual Studio Code instead.

IntelliJ IDEA is JetBrains’ desktop integrated development environment for Java, Kotlin, and JVM projects. It combines code navigation, completion, static analysis, refactoring, debugging, and build-tool workflows.
Since version 2025.3, JetBrains distributes one unified product. Core features remain free, while an Ultimate subscription unlocks additional tooling. New users can try Ultimate for 30 days, then continue with the free feature set or subscribe.
These are the product-specific differences that may matter when deciding whether the software fits your workflow. They are based on documented evidence rather than a universal ranking.
