I use IntelliJ IDEA because it offers very seamless integration with my framework and GitHub. I appreciate its clean and organized UI, which makes navigating it a breeze. The Maven integration makes it smooth and quick to handle new pulls from the main branch. I also find the separate Copilot integration incredibly helpful for simplifying vibe coding. Previously, we were using VSCode, but it was very plain, whereas IntelliJ makes Java development really simple and hassle-free. The initial setup was pretty easy and straightforward.

The merge feature is awesome but can be improved for the excel type file merge conflict resolution. Review collected by and hosted on G2.com.

What I like most about IntelliJ IDEA is its intelligent coding assistant and the productivity boost it gives me. It feels like IntelliJ understands what’s happening in the backend of the code and instantly provides suggestions, whether that’s for code completion or JavaDocs to help fill in documentation. This is really helpful in real-life scenarios when I’m building more complex code, and it also makes it easier to organize and structure the code using OOP principles.

The main thing I dislike about IntelliJ IDEA is its high power consumption, especially for students with less RAM and low-end graphics in their laptops. The startup time, indexing, and background processes can sometimes use a significant amount of memory, particularly during launch. Review collected by and hosted on G2.com.

I use IntelliJ IDEA for Java-based application development, including Spring Boot and Kotlin. I appreciate its clean interface, which is very useful in complex scenarios. The support for different Java options, alongside its good autocomplete and debug features, makes it very efficient to use. It supports various Java versions simultaneously, and the autocomplete significantly enhances efficiency. The debug feature is excellent for catching exceptions before compilation. The initial setup was very easy too. Review collected by and hosted on G2.com.

I use the pro version which unlocks the chat for me, but they could give it in the free version itself with limits. Review collected by and hosted on G2.com.

I like how IntelliJ IDEA seems to understand my code. The smart autocompletion, instant error detection, and refactoring tools actually feel safe to use. It saves me time and helps me focus on thinking through the work, not fighting with the tools. Review collected by and hosted on G2.com.

On large projects, it can feel heavy and sluggish, especially while indexing, and it tends to use a lot of memory. On top of that, some genuinely useful features are locked behind the paid version, which is pretty frustrating. Review collected by and hosted on G2.com.

Its is very useful in terms of coding.

The auto-complete is very useful ,The coding intelligence of inteliij is on next level .

The debugging tools are also very helpful in intellij Idea . they help me in every issue and its very easy to debug. Review collected by and hosted on G2.com.

It is very very heavy on RAM , It almost consumes around 3gb of my ram which makes my system slow.

It has most features unlocked when we pay for the ultimate version Review collected by and hosted on G2.com.

It is easy to use due to its autocompletion features and has a very simple ease of implementation through a simple install and allows use of multiple plugins through marketplace. I use it daily for coding in java and python. It has good integration with Spring Boot, Gradle etc. It has very good customer support and they helped me with the co-pilot setup.

The free version could be provided with more features. Review collected by and hosted on G2.com.

Excellent code intelligence

IntelliJ IDEA is very good at understanding the structure of a project. Its autocomplete, navigation, inspections, and refactoring tools are especially strong for Java, Kotlin, Spring, Maven/Gradle, and large enterprise codebases. Review collected by and hosted on G2.com.

It can be resource-heavy.

IntelliJ IDEA can use a lot of memory and CPU, especially on large projects or when you have many plugins enabled. Indexing, Maven/Gradle builds, and enterprise Java applications can also add to the load. On lower-spec machines, it can end up feeling sluggish compared with lighter editors. Review collected by and hosted on G2.com.

The best parts, in my view:

1. Code intelligence that genuinely saves time

Its autocomplete, refactoring, and error detection are incredibly accurate. It understands context deeply whether you're working with Java, or even frameworks like Spring so it suggests the right thing, not just a thing.

2. Refactoring without fear

Renaming variables, extracting methods, restructuring code it handles complex refactors across large projects safely. This is where it really outshines lighter editors.

3. Built-in tools ecosystem

You don’t need to juggle plugins as much. Things like:

Git integration

Database tools

HTTP client

Debugger

are all first-class and polished.

4. Excellent debugging experience

The debugger is powerful but also easy to use inline values, smart step-into, and conditional breakpoints make tracking issues much faster.

5. Consistency and polish

Everything feels cohesive. UI, shortcuts, workflows they’re designed to work together instead of feeling bolted on.

6. Strong support for JVM languages (and beyond)

It’s especially unbeatable for Java, but it also handles JavaScript, Python (with plugins), and more quite well. Review collected by and hosted on G2.com.

It can be a RAM and CPU hog, especially on large projects. Indexing alone can spike usage and slow your machine on lower-end laptops, it’s very noticeable. Review collected by and hosted on G2.com.

What I like most about IntelliJ IDEA is how smart and helpful it feels while coding. The auto-suggestions, code completion, and built-in tools save a lot of time. It makes development smoother and helps catch mistakes early. Review collected by and hosted on G2.com.

One thing I don’t like about IntelliJ IDEA is that it can feel a bit heavy, especially on systems with lower RAM. Sometimes it takes time to start up or index projects. Also, a few advanced features are locked behind the paid version, which can be limiting. Review collected by and hosted on G2.com.

We do not need to install tons of extensions also there is no need of extra efforts for set up and integration.Debugging is very easy and fast.It is good multiple language selection, better performance. One Drawback is it uses more RAM else overall it is perfect for Developer and Tech Employees. Review collected by and hosted on G2.com.

Tt uses more RAM and the ultimate version is paid. Review collected by and hosted on G2.com.
