Student

The biggest advantage is how smart the IDE is ,code completion, debugging tools, and refactoring features save a lot of time compared to basic editors.

Private

Lack of control for a developer from my personal take, every script automated, the 'dev-support-team' finds a way to mitigate your ability to use it-

Associate software developer

Indexing large projects upon startup can take some time, and it consumes a significant amount of RAM so my device cry.

Business process engineer

Developer friendly because it provides all syntax and the autocomplete feature helps to do more work in less time.

Technical Executive

I develop Spring Boot powered Java backend Services and use the IDE to debug and develop the new services and methods, the inbuilt decompiler is also very useful in the case documentation is not available for an obsecure dependency

Enigneering Manager

It’s a powerful IDE with great features like smart code completion, powerful debugging tools, and seamless integration with version control systems

It also integrates really well with tools like Maven and Git, which makes project management easier.

The out-of-the-box features save me hours of configuration time every week.

Software Engineer

It does not provide the option to open the same project in two different windows which is a drawback for me.

Senior Systems Administrator

JetBrains knows their customer base and their suite of IDE's and developer tools proves this.

The code completion feature with AI is a real life-saver.

Software Developer

UI feels a bit outdated sometimes, overwhelming whit plugin and navigation could be smoother

The versatility and speed are my favorite features of IDEA.

IntelliJ IDEA also performs very well as I very rarely have any times where I need to wait long for it to keep up with code changes.

The only thing that really has bugged me with IntelliJ IDEA is how it does not seem to handle system shutdown well.  

Technical Lead

need better AI co pilot integration for code reviews, code suggestions.

I use it mainly for Scala development but it handles C# code well also.  

I chose to continue using it in my career because it makes sometimes tedious tasks rather simple and saves me a ton of time when building/mending dev environments.

UI UX Designer

Been tinkering with IntelliJ for yonks, it's a solid wizard spinning Java builds before coffee

Great integration with Maven, Gradle, and Git

Software Developer Senior

I use this with my students and for my own purposes when writing cross-platform applications.

Web Developer

It can be a little tough to set up for new users or students who are just starting to code.

Too many services are paid, Maybe provide the AI code completion on a trial without adding in card details

Customer Success Specialist

The software's graphical user interface (GUI) is appealing, and its functionality is exceptional, particularly its ability to execute code through buttons and its various operation modes, such as debugging mode.

Prefer a more ethical-value practise approach-

Jr. Full Stack Developer

It provides out-of-the-box plugin support, syntax highlighting, formatting, refactoring, git support, and plenty of inbuilt tools for making developer's life easier.

This IDE allows simple or complexity development

Fast setup and good integration with GitLab pipelines.

Very smart code completion and suggestions

A very detailed interface with lots of built in functionalities.

ICT Assistant

It helps my software and web development seem easy with its code completion function, it also helps me debug my code with ease.

Internship

Supports plugins, integration with other software like Git, developing Java apps is easy.

Full stack developer

IDEA why because it is time saving while you are developing softwares it is way faster in debugging and straight forward it gives you the best environment for you technology for example i use python and there is no better IDE than pycharm for python code except the UI which is what makes me chose between other IDEs

The easy to use interface and also the tour guide which helps to understand the working of the app.

I use IntelliJ for more than 10 years now and I've never found an IDEA that can compete with it in terms of features, stability and user interface.

Information Technology Engineering

The free version of IntelliJ IDEA, for students is truly groundbreaking as it gives them the opportunity to use a grade integrated development environment (IDE) without any financial strain.

My favorite feature in it is that it does intelligent code completion.

Developer

JetBrains IDEs are feature-rich, smart, and efficient but can be resource-heavy and expensive.

intern

It is unlikely that you have coded with the Java programming language and have never used this program. If this program is not the best in its field, it is undoubtedly one of the best.

I use this IDE for a variety of java programs that I have developed and continue to support.

My experience with IntelliJ started in college, working on mainly java applications so I became rather familiar and comfortable with it over time.

Developer 

My development approach has become tremendously effective because to the easy management of several projects in the same workspace and the smooth connection with version control systems.

The indexing process can be slow for large projects

Even if the software is far from being free, there are many many features that may never be used, but if needed are a life changer !

It can be a bit bulky, and occasionally crashes, or misbehaves.

The software is very expensive, and the support isn't easy to reach (only public forums, no kind of chat/mail/phone support).

It suggests relevant code with anticipation, hence saving lots of time and effort.

Ph.D. Student

The editor provides robust support for various programming languages, including Kotlin, Python, and JavaScript, among others.

Research Associate

Everywhere search lets you search everything from everywhere.

Analyst

Its intelligent code completion, robust refactoring tools and smart suggestions significantly boost my productivity.

I have a very fond recollection of my time with Code::Blocks, it made learning C++ development a very accessible process when compared to the smorgasbord of buttons and configurations needed to get a project building in VisualStudio.

System Software Engineer 

They can still improve the UI .The here are lot of features in code blocks but it's hard to learn about all those features. While handling some projects it's difficult to search for the options and most people don't have the knowledge of the options available.

I really like and love the way that provide differents tools and options for new developers and the way that you can use those tools and functions to learn while you are programming, code::blocks have a great graphic interface to start and learn the way that this kind of software works.

Several more capabilities, including keymap customizations, editor themes, and debuggers, are also included with the IDE.

Front-end developer

what i do not like about code blocks is that it does not have the best UI which could make it difficult for begginers to use for the first time.

A very easy to use IdE with a free access makes it the best choice for c/c++ programmers and provide great features that makes the user experience very smooth.

Principal Software Development Engineer

Researcher

The GUI is nice for learning development of programming.

The majority of my team members enjoy using the IDE because of how straightforward and user-friendly it is.

Software Product Manager

Most of the members love working with the IDE due to its simplicity and ease of operation.

Manager

This was the first integrated development environment (IDE) which I started using during my engineering studies and since then I have developed several academic as well as professional software using this IDE.

still the best editor for C++ but the interface is outdated and look old fashioned.

Freelancer - Developer

The user interface must be changed, it's too outdated for the present time.  

Code::Blocks looks out dated and a new interface would be refreshing.
