CLion2026.2.2

CLion lets developers write, edit, build, test, and debug C and C++ software within one integrated development environment. It reduces the friction of combining a language-aware editor with separate build, testing, and debugging tools, while also supporting embedded and remote development workflows.

Its language engine understands modern C and C++, including templates, constexpr code, and features from the latest standards, so completion, inferred types, function signatures, documentation, and navigation respond to context. Real-time analysis, data-flow analysis, Clangd checks, and Clang-Tidy flag unused or unreachable code, dangling pointers, and null-pointer dereferences as you type. Developers can jump to definitions, declarations, and usages, browse code hierarchies, find files or IDE actions through Search Everywhere, and apply automated refactorings that keep code consistent.

CLion works with major toolchains, popular build systems, and unit-testing frameworks, and includes advanced debugging for everyday application development. Next-edit suggestions and unlimited code completion assist with writing code, while transparent AI costs avoid vendor lock-in. The environment suits beginners, professional C and C++ teams, embedded programmers, and people maintaining large native-code projects.

The freeware Developer Tools release 2026.2.3,262.10968.117 runs on macOS 12 Monterey or later and supports Apple Silicon arm64 hardware. JetBrains aligns CLion with industry security standards, including SOC 2 attestation, and provides SOC 2 reports, penetration-testing summaries, and security questionnaires through its Trust Center to support data protection and compliance with global regulations.
