Category: IDEVerified for 2025
Top Recommended Replacements
VS Code
FREETop Free Alternative
Why we like it
Extremely lightweight and fast; the 'C/C++ Dev Kit' extension provides essential IntelliSense; the 2025 'Agent Mode' allows for automated multi-file refactors; excellent for cross-platform remote development.
Keep in mind
Requires manual configuration of CMake and launch.json files to match CLion's out-of-the-box intelligence; debugging complex C++ templates can be less visual.
Windsurf Editor
FREEBest AI-Native Alternative
Why we like it
A breakout 2025 IDE featuring 'Cascade,' an AI agent that can understand your entire C++ project context, fix build errors in the terminal, and edit header/source files simultaneously.
Keep in mind
Lacks the specialized C++ features like Memory View or the Constexpr Debugger; high-end AI models require a monthly subscription.
Visual Studio 2022/2026
FREEBest for Windows/MSVC
Why we like it
The gold standard for Windows development; unmatched performance profilers and memory diagnostics; full support for the latest C++23/26 standards.
Keep in mind
Windows-only; extremely large installation size; 'Community' edition has strict commercial revenue limits.
Code::Blocks 25.x
FREEBest for Legacy & Low-End PCs
Why we like it
Incredibly lightweight; runs on hardware that modern IDEs won't touch; highly extensible via plugins; completely free with no account requirements.
Keep in mind
Interface is very dated (GTK+); lacks modern AI assistance, deep CMake integration, and advanced refactoring tools.
Qt Creator 15
FREEBest for UI & Cross-Platform
Why we like it
Specialized for the Qt framework but excellent for general C++; very fast and stable; built-in visual UI designer.
Keep in mind
The commercial licensing can be confusing; smaller plugin ecosystem compared to VS Code or JetBrains.
