Alternatives to CLion
C/C++ IDE, free for non-commercial
CLion ranks #2 of 10 in IDEs, with an Alt Score of 89. It is proprietary, freemium from €109.00/year (Personal license, first year; renews at €87.00, then €65.00) and available on Windows, macOS and Linux. 11 of 12 checklist rows are verified against a public source.
CLion is for C and C++ developers who want a full-featured, dedicated IDE rather than a general-purpose editor — from embedded/firmware engineers to those building cross-platform desktop and systems software. It's free for non-commercial use (students, hobbyists, open-source contributors), with paid licenses for professional/commercial work.
On-the-fly static and data-flow analysis flags warnings and errors as you type, with quick-fixes and refactorings. Native support for CMake, Makefile, Gradle, and compilation-database projects, plus an integrated debugger, Valgrind/Google Sanitizers, and a CPU profiler for diagnosing memory and performance issues. Built-in test runners for Google Test, Boost.Test, Doctest, and Catch. Embedded development is supported with on-chip debugging, ARM Peripheral View, FreeRTOS thread view, and STM32CubeMX integration.
You open an existing CMake, Makefile, Gradle, or compilation-database project (or create a new one), and CLion configures the build target and code model automatically. From there you write and navigate code with smart completion, build and run targets, and set breakpoints to step through execution in the integrated debugger, with Git and other VCS integration built in throughout.
