Best C++ IDEs of 2021

It’s hard to keep track of all the great IDEs (Integrated Development Environments) and IDE-like tools available to developers. In fact, this report by JetBrains showed 75% of respondents regularly use IDEs. These tools enhance developer’s workflows, reduce debugging time, and make them more productive.

IDEs go beyond typical text editors by integrating compiling, code completion, syntax highlighting, debugging, profiling, and testing and much more in one comprehensive user interface. Without the power of an IDE, you must use all these components separately in your development workflow. While some developers may prefer that, an IDE can significantly speed your programming and provide an overall better experience.

There is a wealth of choices in IDEs, so focusing on the best C++ IDEs helped narrow down the list of excellent options. In the end, personal preference will outweigh many of the pros and cons of each environment. To help you decide, we’ve assembled a compelling selection of choices along with an analysis of each. Ready? Here are our best C++ IDEs for 2021.

The Best C++ IDEs list – 1. Visual Studio

Visual Studio is the most popular choice for good reasons: this mature tool is cross-platform, supports many programming languages, and is packed with an incredible array of features. Visual Studio’s code compilation technology (named IntelliSense) is widely praised and relied on daily by many developers. It has excellent syntax highlighting, easy to use UI designer, CMake support, and a powerful debugger and profiler system. In addition, it has a huge community so there’s no shortage of know-hows, samples and more.

What functionality Microsoft doesn’t include is often provided by an impressive collection of available Visual Studio extensions. Developers will enjoy a wide selection of extensions for C++.

Fun Fact: Incredibuid is bundled inside Visual Studio to accelerate C++ builds.

4. Eclipse CDT (C/C++ Development Tooling)


Eclipse is a free and open-source cross-platform IDE written in Java and originally constructed to replace IBM’s now-discontinued VisualAge IDE. Eclipse is more of a framework than a complete IDE, relying on a wide array of plugins to provide language-specific functionality. Eclipse supports nearly thirty programming languages, and the C/C++ flavor is named Eclipse CDT (Eclipse C/C++ Development Tooling).

Eclipse is well known for its simplicity and broad community support. It offers all the standard features one would expect in a C/C++ IDE, like code completion, compilation and debugging support, static code analysis, profiling, and refactoring.

5. CodeLite


CodeLite is another free and open-source IDE. It supports C/C++, PHP, and JavaScript and is built with the wxWidgets cross-platform toolkit, allowing it to run on Windows, macOS, Linux, and FreeBSD. The editor is based on the open-source Scintilla project.

CodeLite provides a simple but comprehensive user interface and includes support for project management, refactoring, code completion, syntax highlighting, debugging via GNU’s gdb, and integration with source code management systems like Git and Subversion.

The IDE also includes a wxWidgets creation tool that allows developers to design cross-platform graphical user interfaces easily.

6. Apache NetBeans

Apache NetBeans

Apache NetBeans is an open-source, cross-platform IDE written in Java. It was a student project at Charles University in Prague, Czech Republic, and was initially named Xelfi. The name Xelfi name was a reference to the Delphi IDE for the Pascal programming language. Sun Microsystems bought NetBeans in 1999, then Oracle (which acquired Sun) released it to the Apache project in 2016.

NetBeans has excellent C/C++ support and features a debugger, code folding, projects, templates, and Qt Toolkit support. It also features plugins developed by an active community of contributors.

7. Qt Creator


Qt Creator is a commercial (with free trial) C++ cross-platform IDE for building superb GUI applications using the popular and feature-filled Qt toolkit.

In addition to offering the typical IDE features like compiling, debugging, code completion, profiling, and refactoring, Qt Creator developers benefit from a vibrant ecosystem of design and development tools centered around the Qt toolkit.

Additionally, Incredibuild has excellent integration with Qt creator to reduce Qt build time.

Best C++ IDEs – ID Your Chosen IDE

Choosing the right IDE for you is no easy task. We hope this list of best C++ IDEs has provided insight into the various options available.

While we’ve featured the major contenders and explore their feature sets, nothing will replace hands-on use. We recommend giving your favorites from this list a try with an actual project to see which works best for you.

Many developers use multiple IDEs in different situations. A Windows-centric development project might be best served with Visual Studio, and a macOS application may benefit from Xcode more than other IDEs. However, cross-platform projects, especially those using the wxWidgets toolkit, may benefit from independent projects like CodeLite. If you’re a JetBrains user, CLion is an obvious choice. It has good integration with other JetBrains tools and features a similar user interface and workflow. Qt developers will naturally gravitate toward Qt Creator.

And, of course, you don’t have to use an IDE. Sometimes a simple is well suited to a typical programmer’s editor like Visual Studio Code, Sublime, Atom, or Notepad++.

Whatever you choose, be it a full-blown IDE or a code editor, we recommend you using Incredibuild to accelerate your build-test cycles!
