CLion

CLion’s Quick start guide shows you how to create and run your first project and introduces the product’s core capabilities. If you are new to CLion, there is a set of interactive courses that can help you get familiar with the essential functionalities.

Moving to CLion doesn't mean rebuilding your setup. Open your existing CMake project, Makefile, or compilation database, and CLion picks up your toolchain. Coming from VS Code, CLion reads the settings in c_cpp_properties.json (and applies any changes you make to it), and you can set up code insight for custom project formats and standalone files, too. Keep your OS, your compiler, and your shortcuts with a familiar keymap.If you have a paid license for a product that competes with CLion, we will give you a 25% discount on a standard commercial or personal subscription.Follow our Quick start guide for step-by-step setup instructions.

Yes. CLion works with the agents you already use, including Codex, GitHub Copilot, Junie, Cursor, and Claude, plus any other ACP-compatible agent. JetBrains Air, now in early access, lets you run several agents in parallel and review their work in one place, right in the IDE.

No. You can use your existing agent subscriptions or BYOK, and JetBrains AI is optional if you already have it or want it.

You can try JetBrains Air at no cost with Junie Lite, JetBrains' efficient coding agent for everyday tasks. You only need to sign in with a JetBrains Account. You can also bring agents you already have, using their own subscriptions.
