What is the IntelliJ Platform?

The IntelliJ Platform is a platform for building smart, language-aware IDEs with a comprehensive set of components, including:

  • virtual file system
  • UI framework (action system, toolwindows, etc.)
  • text editor
  • lexing, parsing, abstract syntax trees and other language-specific infrastructure
  • frameworks for implementing navigation, code completion, inspections, intentions, refactorings, etc.
  • version control integration
  • debugger framework
  • graphical unit test runner
The following JetBrains products are based on the IntelliJ Platform:
IntelliJ IDEA

The most intelligent Java IDE


New Objective-C IDE building iPhone, iPad and Mac OS applications


Ruby and Rails IDE with the full stack of essential developer tools


Professional IDE for Web and PHP developers


Lightweight HTML, JavaScript and CSS editor


Lightweight IDE for Python with support of Web development with Django framework


Language Oriented Programming toolset

The IntelliJ Platform is open source, and the code is covered by the Apache 2.0 license. This means that you can build both open source and commercial products on top of the platform without paying any royalties to JetBrains.

Please note that the IntelliJ Platform is not a general desktop application framework, and is only designed to be used for IDE-like applications. Basically, if your application requires a code editor, there's a very good chance that the IntelliJ Platform will be suitable as the underlying framework.
