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.
ReSharper is a Visual Studio extension for.NET developers, first released in 2004. 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. It was also a key revenue source for JetBrains in its early years.
ReSharper provides on-the-fly code quality analysis for C#, VB.NET, XAML, ASP.NET, JavaScript, TypeScript, CSS, HTML, and XML. Its features include code refactoring, code completion, navigation, find usages, and code formatting. The extension offers more than 2,200 on-the-fly code inspections and over 60 refactorings and 450 context actions.

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. The VS Code extension provides real-time code analysis, refactorings, and navigation for C#, XAML, Razor, and Blazor, and includes a Solution Explorer and built-in unit testing support for NUnit, xUnit.net, and MSTest.
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. ReSharper is available as a standalone license or as part of the dotUltimate subscription, which also includes Rider, dotTrace, dotCover, and dotMemory.
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). The name comes from the Kotlin Island, near St. Petersburg. 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.
JetBrains MPS is an open-source language workbench for domain-specific languages.
Ktor is a Kotlin-based programming framework for developing "connected applications", using the same framework on both server (JVM) and client (JavaScript, Android, and iOS).
Kotlin Multiplatform (KMP) is a JetBrains technology that allows developers to share Kotlin code across multiple platforms, including Android, iOS, desktop, web, and server. It reached stable status with the release of Kotlin 1.9.20 in November 2023. The related Compose Multiplatform framework, which enables shared user interfaces, became stable for iOS in 2025.
Team tools
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".
Upsource was 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. It began sunsetting Upsource in 2022, officially ending support for the product in January 2023. In May 2024, JetBrains rebranded Space to SpaceCode to focus on Git hosting and code reviews.
YouTrack is a proprietary, commercial web-based bug tracker, issue tracking system, and project management software developed by JetBrains.
Qodana is a code quality analysis tool that uses static code analysis to help users with code reviews, building quality gates, and the implementation of code quality guidelines. It was publicly launched in July 2023 and can be used with IDEs in JetBrains's ecosystem, has CI/CD pipeline integration, while supporting code analysis in over 60 programming languages.
AI tools
JetBrains AI Assistant is offered in most JetBrains IDEs as a set of AI-assisted software development tools. The assistant uses models from OpenAI and Google, and proprietary models developed by JetBrains, such as the Mellum model released in April 2025.
Junie is an AI coding agent developed by JetBrains, launched in January 2025 in closed preview. Unlike the AI Assistant, which focuses on code completion, Junie is designed to function as an AI agent for coding. In April 2025, JetBrains made Junie generally available.
Others
Datalore is a web application for data analysis and visualization, which is focused specifically on the machine learning environment in Python. JetBrains Academy 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. Certifications were added in November 2021 after community feedback prioritized verifiability of the work done on projects. 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.
Open source projects
In 2009, JetBrains open-sourced the core functionality of IntelliJ IDEA by offering the free Community Edition. It is built on the IntelliJ Platform and includes its sources. JetBrains released both under Apache License 2.0. In 2010, Android support became a part of the Community Edition, and two years later Google announced its Android Studio, the IDE for mobile development on Android platform built on the Community Edition of IntelliJ IDEA and an official alternative to Eclipse Android Developer Tool. After two years of development JetBrains open-sourced Kotlin in February 2012. In June 2015, it was announced that the support of Eclipse ADT would be discontinued, making Android Studio the official tool for Android App development.
In January 2020, JetBrains released a geometric monospaced font named JetBrains Mono, made the default font for its IDEs, under the Apache License 2.0. The font is designed for reading source code by being optimized for reading vertically with support for programming ligatures.
Financials and business model
As a private company, JetBrains does not disclose detailed financial statements. However, its annual highlight reports indicate consistent growth. In its 2023 highlights, the company reported a 5.6% year-over-year revenue growth and noted 11.4 million recurring active users. This followed an 11% revenue growth in 2022, when the company reported having 15.9 million users.
The company's business model is primarily based on software subscriptions. In recent years, JetBrains has adjusted its model in response to market trends. This includes making more of its IDEs available with free, non-commercial licenses, such as for RustRover, and unifying its flagship IDE, IntelliJ IDEA, to offer a single download with both free and paid features.
Educational and research projects
Before the Russian invasion of Ukraine started - between 2012 and 2021 - the company ran and supported several educational and research projects in Russia, often in partnership with universities and other organizations, including:
The Computer Science Club at the St. Petersburg Department of Steklov Mathematical Institute of the Russian Academy of Sciences, which is a joint initiative of JetBrains and the Yandex School of Data Analysis.
The JetBrains Laboratory at Saint Petersburg State University.
The BioLabs Laboratory, a consortium of scientific teams under JetBrains Research.
A Laboratory of Mobile Robot Algorithms.
