Some best free C++ IDEs you need to know

In some previous articles, we have introduced to you an overview about C++, some libraries, instruct you about C++ standard library. Now, we continue the series about C++ with its best free IDEs. We try to mention some of them and tell you its strengths and weaknesses. Now, let’s get started.

1. What is IDE?

An IDE is a coding environment that includes both an editor and a language-specific toolchain. A typical IDE allows the user to edit source code and build executables. A good IDE has the editor and the additional tools set up in such a way as to make a developer more productive.

2. Some of the best free C++ IDEs

2.1. Visual Studio

This IDE is very popular and is a great choice for many developers to build C++ and C# apps. Visual Studio is only available for Windows and macOS, it does not support Linux.

Visual Studio is a full-featured IDE for a reason: powerful debugging, task running, excellent syntax highlighting, easy to use UI, code completion, etc. It also has a very huge community which can support you with tutorials, samples and more.

Developers will enjoy a wide selection of extensions for C++, which Microsoft doesn’t include often.

However, it has a cost to run C++. You’ll need a powerful Windows development machine, and, if you intend to build commercial C++ applications you’ll need to purchase a Visual Studio license.

2.2. Dev C++

Dev C++ is an IDE for beginners in C++. It’s a free, full-featured and integrated IDE, but only support Windows unfortunately. Despite this limitation, it includes support for GCC-based compilers like Cygwin and MinGW.

It’s a quite impressive IDE, which has integrated debugger (using GDB, you can perform all the general debugging operations on source code), international language support, code compilation, syntax-highlighting editor, a tool manager, find and replace options, CVS support, and code printing.

2.3. Code::Blocks

Code:Blocks is another cross-platform, free and open-source IDE for C++ program development. You can expect many standard capabilities from it such as: compiling, debugging, auto code completion, code analysis, code coverage, profiling. It has an outstanding and intuitive interface, which lets you arrange elements by simply dragging and dropping.

This IDE is available for Windows, Linux and macOS. It supports multiple compilers, so you can consider it if you are working with a particular compiler.

However, Code:Blocks has downsides. Many of its functions are fairly basic compared to other more sophisticated and simplified IDEs on the market. Also, it has relatively few plugins available, and not all plugin perform well.

2.4. Eclipse

Another free and open-source IDE that can run on Windows, Linux and macOS for you. Eclipse is very popular and supports nearly thirty programming languages, and the C/C++ flavor is named Eclipse CDT (Eclipse C/C++ Development Tooling).

This IDE is well-known for standard features like code auto-completion, compilation, debugging tools, syntax highlighting, source navigation, static code analysis, profiling and refactoring. Like Code:Blocks, Eclipse also features an interface with drag-and-drop functionality.

However, Eclipse sometimes can crash and is not very stable when you use it on large projects, as it requires a lot of resources.

2.5. NetBeans

The final free and open-source IDE for building apps in C++ in this article is NetBeans. It’s written in Java like Eclipse.

Its features and supports are amazing with fast code completion and code folding, syntax highlighting, bracket matching, refactoring, integrated multi-session GDB debugger. The UI is clear, simple and friendly. You also can get plugins from its active community of contributors.

However, like Eclipse, sometimes it requires lots of memory and will end up perform kind of slow.

3. iRender - Powerful cloud service for C++

In this article we only mention some of the best free IDEs for C++. Of course there are many good IDEs out there for developers, but they are either not free or are limited to few platform. We will write about them in another article.

At iRender, we provide multiple GPUs for renting with state-of-the-art RTX3090. Our remote machines are Optimized for Scientific Computing, Machine Learning, Deep Learning.

We support not only C++, but also other programming languages such as: Python, Java, R, and many IDEs and libraries like above.

This is our packages tailored for AI/ Deep Learning:

You can also read our article about how RTX3090 be the best choice for AI/ Deep Learning (Is RTX3090 the best GPU for Deep Learning). Plus, at iRender, we provide you more support than just those hardware.

NVLink available for better performance

If 24GB VRam is not enough for your project, we always have NVLink to help you access more than that. You can access this article to know how to set up NVLink on our machine.

Free and convenient transferring tool

iRender offers a powerful and free file transfer tool: Gpuhub Sync. With fast file transfer speed, large data capacity, and completely free. You can transfer all the necessary data into our Gpuhub Sync tool at any time without connecting to the server. The data will be automatically synchronized in the Z drive inside the server, ready for you to use.

Flexible price

Besides hourly rental, you can always save from 10% to 20% with our Fixed Rental feature. For those who’s in need of a server for more than a day, or have extremely large projects, we advise to choose a daily/ weekly/monthly rental package. The discount is attractive (up to 10% for daily packages, 20% on weekly and monthly packages), and you don’t have to worry about over-charging if you forget to shutdown the server.

Real human 24/7 support service

Users can access our web-based online platform and use multiple nodes to render at the same time. Hence, with us, it does not matter where you are present – as long as you are connected to the internet, you can access and enjoy the 24/7 rendering services that we provide, and if you meet any issue, our real human 24/7 support team is always ready to support you.

With these advantages and no hidden cost when using our machine, we believe it’s worth trying your project. You can create an account via this link to experience our service. And don’t hesitate to contact us via WhatsApp: (+84) 916806116 for advice and support.


Thank you & Happy Training!
