Another great product from JetBrains! I couldn't be more happier developing applications using Java (and on some other Python) with this IDE. great features and friendly environment. Debug features and more important cross-platform feature is very reliable and strong. Review collected by and hosted on G2.com.

The installation and setup is a bit bulky I would say. moreover licensing fee always are a bit of concern for developers and companies. Review collected by and hosted on G2.com.

what i like best about the IntelliJ Idea everything will get in single platform for example we can easily manage the git and debugging is so easy as compare to another tool and what i most like tool with nice UI. Review collected by and hosted on G2.com.

its not a disadvantage but as a fresher tool is more complex for initial stage. Review collected by and hosted on G2.com.

IntelliJ IDEA has been instrumental in boosting my productivity as a B.Tech ECE student working on Python, AI, and embedded systems projects. The smart code completion is exceptionally accurate and context-aware, often predicting exactly what I need to write next. The extensive plugin ecosystem allows me to customize the IDE for different workflows, from Python development with scientific libraries to embedded C/C++ programming. The integrated debugging tools are powerful and intuitive, making it much easier to track down issues in complex codebases. The built-in version control integration streamlines my Git workflows, and the code refactoring capabilities help maintain clean, maintainable code across projects.

The main drawback I've encountered is the significant resource consumption, particularly RAM usage which can be demanding on mid-range laptops. During large project loads, the initial indexing process can take considerable time and occasionally causes lag, which interrupts the workflow. The IDE can feel sluggish when working with multiple projects simultaneously or when plugins are heavily utilized. Additionally, the learning curve for some advanced features is steep, and the sheer number of configuration options can be overwhelming for newcomers. Review collected by and hosted on G2.com.

I like IntelliJ IDEA for its intelligent code completion, powerful refactoring tools, and excellent debugging support. It boosts my productivity by understanding my code in depth, helping me catch errors early, and making even complex codebases easier to navigate, work with, and maintain over time.

IntelliJ IDEA can be fairly resource-intensive, particularly when working on large projects, and it may feel sluggish on systems with limited memory. In addition, some of the more advanced features are only available in the paid version, which can be a drawback. Review collected by and hosted on G2.com.

IntelliJ IDEA is best ide for Java development, now it has support for few other languages and frameworks Review collected by and hosted on G2.com.

Dislike about IntelliJ IDE is it consumes more CPU and RAM. It takes longer to load during opening Review collected by and hosted on G2.com.

I primarily use IntelliJ IDEA for backend and full-stack development, especially for Java, Kotlin, and large codebases. I like how it saves me time and mental effort by handling heavy lifting, code navigation, refactoring, and catching issues early on. This makes working with large and unfamiliar codebases less painful and allows me to focus on the logic instead of worrying about the IDE. What I like most is its reliable code intelligence, where navigation, refactoring, and error detection are dependable even in large projects. The consistency of the experience across different projects is great, as the shortcuts and workflows remain the same, reducing context switching. Most features are well thought out and stable, which is important when using the IDE daily. Additionally, we switched from using Eclipse and lighter editors mainly because IntelliJ offered better out-of-the-box code intelligence, navigation, and refactoring, especially for larger Java and Kotlin projects.

The main downside for me is the performance. It can be heavy on memory and CPU, especially with large projects, and it's noticeable when indexing or running multiple services locally. It works best when the machine has enough resources. Another thing is the learning curve. It's very powerful, but that also means a lot of settings and features, which can feel a bit overwhelming at first. You don't benefit from everything immediately unless you spend time learning the IDE. Also, the paid version can feel expensive for individual developers, even though the features are solid, but you have to decide if the cost makes sense for your use case.

Intelligent Code Analysis: Unlike basic editors, IntelliJ "understands" the context of my code. The way it suggests naming conventions, detects dead code, and offers "Quick-fixes" (Alt+Enter) saves me from thousands of small errors daily.

Refactoring Power: The automated refactoring tools—like renaming classes across the entire project or extracting methods—are incredibly safe and reliable. It handles the dependency updates perfectly.

Integrated Ecosystem: I love that I don't have to leave the IDE. The built-in Database Client, HTTP Client (for testing APIs), and the deep Git integration (especially the conflict resolution tool) are superior to standalone tools.

Framework Support: Its native support for Spring Boot and Micronaut makes configuring beans and navigating endpoints seamless. Review collected by and hosted on G2.com.

Resource Intensity: It is a "heavy" application. On machines with less than 16GB of RAM, performance can lag, especially during the initial project indexing phase which can be quite slow.

Pricing: The Ultimate Edition is quite expensive for individual freelancers or small teams compared to free alternatives like VS Code.

Steep Learning Curve: There are so many features and keyboard shortcuts that it takes a few months to truly master the workflow and find where everything is buried in the settings.

UI Updates: Some of the recent "New UI" changes can be polarizing for long-time users who prefer the classic, more information-dense layout. Review collected by and hosted on G2.com.

What I like the most about IntelliJ is how intelligent it actually is. The code suggestions and auto-completion feel s amazing. It detects issues in real time, gives quick-fix options, and helps me write cleaner, more consistent code. I also love the integrated Git tools, I can commit, push, or view diffs without leaving the ide. Another big plus is how well it handles frameworks like spring boot and languages like kotlin or javascript everything works seamlessly out of the box. Review collected by and hosted on G2.com.

The only downside for me is how heavy it can be. On a mid-range laptop, it sometimes slows down when working on large projects, especially during indexing. I also think the pricing could be more accessible for individual developers or small freelancers. Apart from that, it’s a powerful but resource-hungry ide. Review collected by and hosted on G2.com.

I’ve been using IntelliJ IDEA for my Java and RestAssured automation work, and it has really boosted my productivity. The interface feels clean, intuitive, and packed with features that make coding smoother. I particularly like the powerful code suggestions and debugging tools—finding and fixing issues has become much faster. RestAssured integration works seamlessly, and IntelliJ’s smart autocomplete saves a lot of time when writing test scripts.

The ability to manage dependencies through Maven/Gradle is another highlight, and built-in test runners make it easy to execute and analyze results. Overall, IntelliJ feels like a complete package for someone working heavily with Java and APIs. Review collected by and hosted on G2.com.

It can be resource-heavy at times, especially on lower-spec machines. Review collected by and hosted on G2.com.

I like IntelliJ IDEA for its intelligent assistance and developer-focused experience. The smart code completion, real-time code analysis, and quick-fix suggestions significantly reduce errors and help me write clean, efficient code faster. I really value the powerful debugging and refactoring tools, which make it easy to understand complex logic, optimize code, and safely improve existing implementations. The clean and intuitive UI with fast navigation saves time during both development and interview practice. Features like Search Everywhere, Go to Definition, and Find Usages make understanding large codebases much easier. I appreciate that it integrates very well with other tools and software, especially Git and GitHub, making version control seamless. Additionally, the initial setup was fairly easy and straightforward, with a setup wizard that made the first experience smooth. Review collected by and hosted on G2.com.

One challenge is its high system resource usage. On machines with limited RAM or lower specifications, the IDE can feel heavy, with slower startup times and occasional lag, especially when working on larger projects. Another area is the learning curve for beginners. Because IntelliJ IDEA offers so many advanced features, new users may initially feel overwhelmed and may not fully utilize its capabilities without guidance. Review collected by and hosted on G2.com.
