It’s my daily driver for Java and more. The plugin ecosystem is outstanding, and its seamless integration with a wide range of technologies lets me spin up complex environments quickly. I also appreciate how it brings support for so many different frameworks together in one place, which makes it easier to stay productive without constantly switching tools.

It can be fairly resource-heavy, particularly in terms of memory usage and the time it takes to index when opening large projects. To run smoothly, it really requires a powerful machine. Review collected by and hosted on G2.com.

The intelligent code completion and refactoring features in IntelliJ IDEA are truly impressive. The IDE seems to anticipate my intentions, providing context-aware suggestions that greatly accelerate the development process. Its built-in tools for debugging, version control integration with Git, and smooth support for testing frameworks such as TestNG and JUnit make it a comprehensive solution for QA automation tasks. Furthermore, the extensive plugin ecosystem enables us to tailor the IDE to our particular requirements, including integrations with Maven, Gradle, and various CI/CD tools.

IntelliJ IDEA tends to be resource-intensive and can become sluggish, particularly when handling large projects or running on computers with limited RAM. The initial indexing phase often requires a substantial amount of time, which can hinder productivity when starting new projects. Furthermore, the licensing cost for the Ultimate edition is quite high, especially for larger teams. The sheer number of features available may also be daunting for newcomers, resulting in a steeper learning curve compared to more lightweight IDEs such as VS Code.

I like IntelliJ IDEA because it automatically detects Spring configurations and provides smart suggestions for annotations. I find the running and testing of APIs directly inside the IDE very helpful. The built-in debugger and API testing tools are features I really appreciate, and it reduces the manual configurations, making configurations easy. The support for Java projects, especially for Spring, is much better compared to what I used before. Review collected by and hosted on G2.com.

I feel it's a bit heavyweight, sometimes lags my system a bit. High memory cost and startup time. Review collected by and hosted on G2.com.

I really appreciate how IntelliJ IDEA makes code navigation seamless. It's definitely better than other IDEs like VS Code when it comes to jumping from function to function and understanding the flow. The setup was also pretty easy and intuitive, making it straightforward even for a first-time user to navigate and install extensions. Overall, these aspects stand out for me and make my coding experience smoother. Review collected by and hosted on G2.com.

Sometimes I feel like IntelliJ IDEA crashes a lot when it maybe goes out of memory. I think the way it consumes memory can be improved so that it doesn't go into frequent crashes. Review collected by and hosted on G2.com.

“One of the new things I like about IntelliJ IDEA is its improved performance and smarter code assistance. Enhanced refactoring suggestions, better Spring and Java inspections, and more accurate code navigation help speed up development. The UI improvements and better integration with build tools and version control also make the overall experience smoother and more productive. Review collected by and hosted on G2.com.

“IntelliJ IDEA could improve startup time and memory usage, especially for large projects. Occasionally, indexing can be resource-intensive and slow down the system. Improving performance tuning options and making background processes more transparent and controllable would enhance the overall developer experience Review collected by and hosted on G2.com.

Best IDE possible, amazing UI, clean updates, really good performance, supports mostly every tool. In built support for Github Copilot elevates the experience. I use the ultimate version and support for any issue is resolved very quickly. Review collected by and hosted on G2.com.

In certain scenarios, i have seen it crashes and goes in loop until and unless you restart the application. Review collected by and hosted on G2.com.

What I like most about IntelliJ IDEA is how much it simplifies my daily development work. The code completion is very accurate and usually understands what I’m trying to write before I finish typing. It helps me move faster and make fewer mistakes.

I also really appreciate the refactoring tools. Renaming variables, extracting methods, or restructuring code feels safe because the IDE handles dependencies reliably. It gives me confidence when working on larger projects.

The debugger is another strong point. I can easily inspect variables, test expressions, and trace issues without wasting time. Git integration is smooth as well — committing, resolving conflicts, and reviewing changes is straightforward.

Overall, IntelliJ IDEA feels stable, well-designed, and built for developers who care about productivity. After using it for some time, it’s hard to switch to other IDEs because everything feels less efficient. Review collected by and hosted on G2.com.

One thing I dislike about IntelliJ IDEA is that it can be quite heavy on system resources. On larger projects, it sometimes consumes a lot of RAM and can feel slow, especially during indexing. If the machine isn’t powerful enough, the performance drop is noticeable.

Startup time can also be slower compared to lighter editors. When I just want to quickly open a small file or make a minor change, it sometimes feels like overkill.

Another minor frustration is that some advanced features are only available in the Ultimate version, which can be expensive for individual developers or students.

That said, most of these downsides are manageable, but performance and resource usage are probably the biggest drawbacks in my experience. Review collected by and hosted on G2.com.

I appreciate IntelliJ IDEA for its fast search capabilities, integration tests, and fast remote debugging. The best auto-completion feature stands out to me, and I’ve never experienced the IDE hanging even when I open 20 instances. I enjoy the Lombok support, custom code formatter support, the Git plugin, and the availability of plugins for all AI coding tools. Running local builds on Maven projects is smooth, and the community support is top-notch. I also find the extensive shortcuts and keymap support, along with the high performance, to be valuable.

Strong support for AI Coding assistants like Cursor. Review collected by and hosted on G2.com.

What stands out most about IntelliJ IDEA is how smart it feels while you’re coding. Its code completion, refactoring tools, and static analysis are some of the best available—they don’t just suggest syntax, they actually understand the structure and intent of your code. That makes writing and maintaining code much faster and less error-prone. Review collected by and hosted on G2.com.

One of the main downsides of IntelliJ IDEA is that it can be resource-heavy. It tends to use a lot of memory and CPU, especially on large projects, which can slow down your machine if you don’t have strong hardware. Review collected by and hosted on G2.com.
