Take a quick tour of CLion

Smart Editor Code better, refactor easily

Knowing your code through and through, CLion can take care of the routine while you focus on the important things. Boost your productivity with the keyboard-centric approach (Vim-emulation plugin is also available in plugin repository), full coding assistance, smart and relevant code completion, fast project navigation, intelligent intention actions, and reliable refactorings.

Problem Solver Improve code quality on the fly

With CLion, you can create code that's beautiful and correct at the same time. Potential code issues are identified instantly and fixed as you type.

Code Generation Code faster

Save time on unnecessary typing as the IDE generates code for you. Add class members, wrap a block of code with a statement and more, with simple keyboard shortcuts.

CMake Benefit from seamless integration

CLion supports the well-known CMake build system and uses it as a project model. It takes all the project's information (like source files, compiler settings, targets description, etc.) and handles all your changes in CMake-files automatically, also running the 'cmake' command during the build phase.

Debugger Inspect the state of your app easily

Investigate and solve problems with ease using breakpoints, watches and expression evaluation through CLion's convenient interface. Change variable values even as you debug to investigate an issue in more depth.

Universal Environment Everything you need is inside

In addition to C/C++, in CLion you can use JavaScript, XML, HTML and CSS and enjoy the same code editing and transformation features like syntax highlighting, analysis, completion, navigation and refactoring. The IDE seamlessly integrates with the most popular version control systems including Git, Mercurial, and Perforce, and a number of issue trackers.
