IntelliJ IDEA (pronounced/ɪnˈtɛlɪdʒeɪ/in-TEL-ih-jay "idea"[3]) is anintegrated development environment (IDE) written inJava for developing computer software written in Java,Kotlin,Groovy, and otherJVM-based languages. It is developed byJetBrains (formerly known as IntelliJ) and is available as anApache 2 Licensed community edition withproprietary license for some bundled plugins,[2][4] and in a proprietary commercial edition. Both can be used for commercial development.[5][6]
The first version of IntelliJ IDEA was released in January 2001 and was one of the first available Java IDEs with advanced code navigation andcode refactoring capabilities integrated.[7][8]
In 2009, JetBrains released the source code for IntelliJ IDEA under theopen-sourceApache License 2.0.[9][10] JetBrains also began distributing a limited version of IntelliJ IDEA consisting of open-source features under the moniker Community Edition. The commercial Ultimate Edition provides additional features and remains available for a fee.
In a 2010InfoWorld report, IntelliJ received the highest test centre score out of the four top Java programming tools:Eclipse, IntelliJ IDEA,NetBeans andJDeveloper.[11]
In December 2014, Google announced version 1.0 ofAndroid Studio, anopen-source IDE forAndroid apps, based on the open source community edition.[12] Other development environments based on IntelliJ's framework includeAppCode,CLion,DataGrip,GoLand,PhpStorm,PyCharm,Rider,RubyMine,WebStorm, andMPS.[13]
In September 2020,Huawei announced and released version 1.0 ofDevEco Studio, an open-source IDE forHarmonyOS apps development, based onJetbrains IntelliJ IDEA with Huawei's SmartAssist forWindows andmacOS.[14]

It supports databases likeMicrosoft SQL Server,Oracle,PostgreSQL,SQLite, andMySQL can be accessed directly from the IDE in the Ultimate edition, through an embedded version ofDataGrip, another IDE developed by JetBrains.
