IDEs
Current
The following is a non-exhaustive list of integrated development environments (IDEs) distributed by JetBrains.
The JetBrains Marketplace offers 8,860 plugins that extend the functionality of JetBrains IDEs.[47]
ReSharper
ReSharper is a Visual Studio extension for .NET developers, first released in 2004.[48] It is JetBrains' longest-standing commercial product and, according to JetBrains, has accumulated over 2.5 million downloads, making it the most popular extension on the Visual Studio Marketplace.[49] It was also a key revenue source for JetBrains in its early years.[50]
ReSharper provides on-the-fly code quality analysis for C#, VB.NET, XAML, ASP.NET, JavaScript, TypeScript, CSS, HTML, and XML.[51] Its features include code refactoring, code completion, navigation, find usages, and code formatting.[52] The extension offers more than 2,200 on-the-fly code inspections and over 60 refactorings and 450 context actions.[53]
Starting with version 2026.1, ReSharper expanded beyond Visual Studio to support Visual Studio Code and compatible editors such as Cursor, bringing JetBrains' C# tooling to a broader range of development environments.[54] The VS Code extension provides real-time code analysis, refactorings, and navigation for C#, XAML, Razor, and Blazor, and includes a Solution Explorer as well as built-in unit testing support for NUnit, xUnit.net, and MSTest.[55]
ReSharper's development influenced the creation of JetBrains' standalone .NET IDE, Rider; although plans for a dedicated ReSharper IDE were explored and later abandoned after the release of Visual Studio 2005, the work done on ReSharper ultimately formed the foundation for Rider.[56] ReSharper is available as a standalone license or as part of the dotUltimate subscription, which also includes Rider, dotTrace, dotCover, and dotMemory.[57]

Programming languages
Kotlin is an open-source, statically typed programming language that runs on the Java Virtual Machine and also compiles to JavaScript or native code (via LLVM).[58] The name comes from the Kotlin Island, near St. Petersburg.[59] In May 2017, Google announced first-class support for Kotlin on Android, and at Google I/O 2019, Google declared Kotlin its preferred language for Android app development.[60][61]
JetBrains MPS is an open-source language workbench for domain-specific languages.[62]
TeamCity is a continuous integration and continuous delivery server developed by JetBrains. It is a server-based web application written in Java. The New York Times reported that TeamCity may have been used by Russian hackers of US governmental and private agencies, in potentially "the biggest breach of United States networks in history".[67]
Upsource is a code review and repository browsing tool supporting Git, GitHub, Mercurial, Perforce and/or Subversion repositories from a central location. JetBrains released a new developer collaboration tool, Space, in 2019.[68][69] It began sunsetting Upsource in 2022, officially ending support for the product in January 2023.[70] In May 2024, a rebranding from Space to SpaceCode is initiated for the platform to focus on Git hosting and code reviews.[71]
JetBrains AI Assistant is a feature integrated into most JetBrains IDEs. It provides AI-powered code completion, explains code, generates documentation, and suggests refactorings. The assistant uses models from OpenAI and Google, as well as proprietary models developed by JetBrains, to provide its functionality.[75]
In April 2025, JetBrains released Mellum, a 4-billion-parameter large open-source language model created by JetBrains and released under the Apache 2.0 license. It was trained on a dataset of permissively licensed source code and is designed to be a "focal model" specializing in code completion and other coding-related tasks. It serves as one of the models powering the AI Assistant.[76][77][78][79]
Others
Datalore is a web application for data analysis and visualization, which is focused specifically on the machine learning environment in Python.[80] JetBrains Academy[81] is an online platform to learn programming, including such programming languages as Python, Java, and Kotlin. The Academy was introduced by JetBrains in 2019, and reached 200,000 users by July 2020.[82][83] Certifications were added in November 2021 after community feedback prioritized verifiability of the work done on projects.[84] JetBrains has also developed the EduTools plugin for students, which is compatible with IntelliJ IDEA (Ultimate, Community, Educational), Android Studio, CLion, GoLand, PhpStorm, PyCharm (Professional, Community, Educational), WebStorm.[37]
