▶ Product description

It is a capable and ergonomic IDE for JVM. Every aspect of IntelliJ IDEA has been designed to maximize developer productivity. Together, intelligent coding assistance and ergonomic design make development not only productive but also enjoyable.

Deep intelligence

After IntelliJ IDEA has indexed your source code, it offers a blazing fast and intelligent experience by providing relevant suggestions in every context: instant and clever code completion, on-the-fly code analysis, and reliable refactoring tools.

Out-of-the-box environment

Mission-critical tools such as integrated version control systems and a wide variety of supported languages and frameworks are all available — no plugin hassle included.

Smart code completion

While the basic completion feature suggests names of classes, methods, fields, and keywords within the visibility scope, Smart completion suggests only types that are expected in the current context.

Framework-specific assistance

While IntelliJ IDEA is an IDE for Java, it also understands and provides intelligent coding assistance for a large variety of other languages such as SQL, JPQL, HTML, JavaScript, etc., even if the language expression is injected into a string literal in your Java code.

Greater Productivity

IntelliJ IDEA predicts your needs and automates tedious and repetitive development tasks so that you can stay focused on the big picture.

Unobtrusive intelligence

The coding assistance in IntelliJ IDEA is not about only the editor: It helps you stay productive when dealing with other aspects as well (e.g., filling out a field, searching over a list of elements, accessing a tool window, or toggling a setting).

▶ Product features

Deep insight into your code

IntelliJ IDEA analyzes your code, looking for connections between symbols across all project files and languages. Using this information, it provides in-depth coding assistance, quick navigation, clever error analysis, and, of course, refactorings.

Ergonomic development environment

Every aspect of IntelliJ IDEA is designed with ergonomics in mind. IntelliJ IDEA is built on the principle that every minute a developer spends in the flow is a good minute, and things that break developers out of that flow are bad and should be avoided.
