JetBrains tools adhere to industry-leading security standards, including SOC 2 certification, ensuring your organization’s data is protected and our products are compliant with global regulations.
CLion does the job
Embedded development
CLion fully supports the STM32CubeMX and PlatformIO projects. You can use any embedded toolchain, including the IAR toolchain, and set up a custom compiler. Moreover, the on-chip debugging functionality includes RTOS integration and peripheral view.
What’s new in CLion 2025.1
Support for out-of-project files in CLion Nova
CLion Nova now provides complete code analysis and code assistance functionality for header and source files that are not included in a project. This can be helpful, for example, when you just need to edit some code in a .cpp file that is not part of the build.
Qt renderers in the debugger
When you’re examining a suspended Qt application, the debugger now allows you to view variables in a human-readable form. This makes it easier to develop and debug cross-platform applications with the Qt framework in CLion.
west build options and sysbuild support
When working with Zephyr projects, you can now use the west build command options, as well as sysbuild as your primary build system. This provides more flexibility when configuring Zephyr projects, including those involving hardware.
ST-LINK debug server experimental
We’ve added an ST-LINK debug server template designed specifically for STM32 chips. It contains only the most basic and essential settings, simplifying debugging for STM32 projects.
All essential integrations

A complete coding experience so you can develop in C and C++ quickly and safely without switching to external tools
What developers say about CLion
Matt Godbolt
Compiler Explorer
CLion takes a lot of the toil out of C++, allowing me to concentrate on the interesting part: problem solving.
Jason Turner
C++ Weekly, CppCast,
Trainer, Consultant
CLion has been indispensable for me when refactoring large codebases. The refactoring tools and the real-time feedback in the IDE about which lines still need to be updated are excellent time savers. Each release gets better and more responsive than the last!
Prof. Dr. Rodriguez-Losada
Conan, JFrog
CLion is fantastic, finally the C++ high quality cross-platform IDE with CMake as first class build system we were waiting for.
Erkki Salonen
Software Developer
CLion’s powerful refactoring and code model that understands dependencies between items have already changed my software design process. One can dig out quite a bunch of bugs even before running the application.
Matthew Davey
dotBunny
Both of these tools (CLion and Rider) help our team on a daily basis, allowing developers to perform their tasks quickly and efficiently, all the while seamlessly integrating with numerous parts of our pipeline.
