IntelliJ IDEA Reviews & Product Details

I use IntelliJ IDEA daily for Java and Spring Boot development, along with occasional work on microservices and REST APIs. It’s my primary IDE for writing, debugging, and refactoring code, as well as managing Maven/Gradle projects. I think the best part of using this software is how intelligent and developer-friendly the IDE feels during daily use. The smart suggestions, quick fixes, and refactoring options are extremely accurate and save a lot of manual effort. Review collected by and hosted on G2.com.

A area that could be improved is the learning curve. With so many powerful features available, new users may feel overwhelmed and may not fully utilize the IDE at first. To improve this, better performance optimization for large projects and low-spec machines would be helpful. Review collected by and hosted on G2.com.

IntelliJ IDEA’s biggest strength is how much it takes off your mental load. Smart code completion, deep refactoring, and instant error detection let you focus on logic instead of syntax. It understands the codebase, not just the file you’re in, which makes navigating, debugging, and maintaining large projects faster and less error-prone. Review collected by and hosted on G2.com.

The main downside is how resource-heavy it can be. On large projects it consumes a lot of memory and CPU, which can slow things down on weaker machines. Startup time can also be noticeable, and some advanced features feel overkill when you just want to make a quick, lightweight change. Review collected by and hosted on G2.com.

IntelliJ IDEA stands out thanks to its smart code completion and deep understanding of code structure. It often anticipates what I’m about to write, flags potential issues in real time, and suggests quick fixes that genuinely save time. The refactoring tools feel extremely reliable, even when working on large, complex projects. On top of that, the built-in integrations for Git, Maven, and Gradle help keep day-to-day development smooth and efficient. Review collected by and hosted on G2.com.

It can be fairly resource-heavy, especially on systems with limited RAM. The initial startup time can also feel slow, and the Ultimate version is quite costly for individual developers or beginners. Review collected by and hosted on G2.com.

IntelliJ IDEA is one of the best IDEs on the market for Java development. It’s built to help developers focus on writing code rather than spending time configuring settings in the IDE. I have been using IntelliJ IDEA for the last two years, and I’m really loving it.

Some features, like code suggestions, autocomplete, running servers, and debugging, are amazing and make day-to-day development smoother. Syntax checking is also an important feature in my book. The built-in store for plugins is very helpful as well, since it makes it easy to add new capabilities to IntelliJ IDEA.

Overall, I like the UI: things are placed where they should be, and the color scheme is nice and helps me identify things quickly. Review collected by and hosted on G2.com.

I feel that IntelliJ IDEA is starting to fall behind in the AI race compared with the competition. At the moment, it doesn’t seem to offer any free AI code assistance, even with usage limits, while other tools do. 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.

IntelliJ IDEA makes coding faster and easier with some quite impressive features, like auto-completing the code when it understands the intention of the code I am typing, reducing the time in coding. It clearly highlights the errors in the code while typing or any other syntax errors. Debugging and running programs is simple and easy, and everything is available in one place.

IntelliJ IDEA needs to work on the system resource allocation, as it uses a lot of system memory and feels slow on low end laptops. While working on big projects, it takes lot of time to load the code, and the laptop heats up significantly. Some features must be purchased to use and for beginners it is not so easy to use.

Its powerful intelligence and developer productivity features.

Excellent code completion, refactoring, and static code analysis that catch issues early.

Deep understanding of Java, Spring Boot, and frameworks, making navigation and debugging very efficient.

Built-in tools for Git, testing, profiling, and database access reduce the need for external plugins.

Smart suggestions and inspections help write clean, maintainable code faster. Review collected by and hosted on G2.com.

It can be resource-heavy, consuming significant memory and CPU on large projects.

Some advanced features are locked behind the paid (Ultimate) edition, which can be costly. Review collected by and hosted on G2.com.

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.
