The most useful thing about IntelliJ IDEA is its excellent code intelligence and developer-friendly interface. Its smart code completion, navigation, debugging, refactoring, and error detection make development much faster and easier, especially for Java and Spring Boot projects. I also find its integrations with Git, Maven/Gradle, databases, testing frameworks, and other development tools very convenient because most of my workflow can be managed from one place. Performance is generally good for large projects, although it can use more system resources than lightweight editors. The pricing is reasonable for professional development because the productivity benefits can justify the cost, while the free options are useful for learning and basic development. The documentation, community, and built-in guidance also make onboarding easier. Its AI features are another useful addition for code generation, explanations, debugging, and refactoring. Overall, IntelliJ IDEA is a powerful IDE that significantly improves productivity and is particularly valuable for professional Java development. Review collected by and hosted on G2.com.

The main downside of IntelliJ IDEA is that it can feel heavy and use more RAM compared to lightweight editors like VS Code. Some features can also take time to learn, especially for beginners. The paid Ultimate version may be expensive for individual users, and some advanced features require a subscription. While its integrations and AI features are useful, they can sometimes feel overwhelming. Overall, it is powerful, but it may be more than necessary for small or simple projects.

I primarily use IntelliJ IDEA for Java backend development. I like its intelligent code completion, fast navigation, built-in debugging, and seamless Git integration. It makes Java development more efficient and improves productivity. It speeds up development with smart code completion, easy debugging, built-in Git support, and powerful refactoring tools. The smart code completion reduces typing, navigation makes it easy to find classes and methods, the debugger helps quickly identify issues, and Git integration simplifies version control without leaving the IDE. The initial setup was straightforward. The installation wizard and built-in support for Maven and Git made it easy to get started. Review collected by and hosted on G2.com.

I find IntelliJ IDEA can be resource-intensive on large projects, and some advanced features have a learning curve for new users like me. Features like advanced debugging, profiling, and custom IDE settings can take some time to learn. Review collected by and hosted on G2.com.

Feasible for writing the java code, and implementation of spring services was easily done with the less amount of steps also mostly we can use more extensions which makes to write our code in a structured way, easy to handle git commands, By seeing that UI our mind gets more interested and focused to write a code.

Slow startup times and high memory usage also Complex project setup like Initial configuration for external build tools, plugins, or specific non-standard frameworks can be tedious. Review collected by and hosted on G2.com.

Jetbrains IDEs have a consistent UI/UX over different Operating Systems, IntelliJ is no different. Your learning is used accross other IDEs and Operating System - they have been consistent for years, but also keep improving the experience with care for our workflow.

It is easy to add integration and plugins - and there are plenty on the community, of course for all AI major providers. Review collected by and hosted on G2.com.

Performance was a challenging in the past, but this has improved consistently over the years, and knowdays it isn't an issue anymore.

It is a bit pricier, as it is subscription based - but for professionals is well worth the price. Review collected by and hosted on G2.com.

I use IntelliJ IDEA for my day-to-day Java and Kotlin development. The thing I like most about it is the built-in debugger. The debugging experience in IntelliJ IDEA is really smooth and reliable. I’ve tried multiple IDEs, such as Cursor, Antigravity, and VS Code, but none of them has given me the same kind of debugging experience as IntelliJ IDEA. Review collected by and hosted on G2.com.

With the recent introduction of AI agents in coding IDEs, IntelliJ IDEA feels like it’s lacking. It does offer integration with GitHub Copilot and Cursor, but the accuracy and overall capability of the newer AI agent–powered tools are far better than what IntelliJ IDEA currently provides.

As a Java developer, I really like IntelliJ IDEA because it offers excellent support for Java and Spring Boot development. The intelligent code completion, strong refactoring tools, solid debugging features, Git integration, and built-in code inspections help me write clean, maintainable, and reliable code more efficiently. I also find the navigation features and project-wide search especially helpful when I’m working on large enterprise applications and need to move quickly across the codebase.

The main thing I dislike about IntelliJ IDEA is how resource-intensive it can be, especially with large Java/Spring Boot projects. It often uses a lot of RAM and CPU during indexing, and it can feel even heavier when I’m running multiple services at the same time. I also find that some of the more advanced features take a while to learn. Still, despite these drawbacks, the productivity benefits outweigh them for me overall.

As a Java Developer I would prefer Intellij IDEA as a IDE for java over anything, Intellij IDEA provides a very simple, easy to understand UI, the best thing is that you can write Java codes and execute them very easily. Review collected by and hosted on G2.com.

Using some other AI rather than JetBrains AI is a bit difficult, since in other IDEs we can use claude code or codex and attach files directly from the command line, but the same thing in Intellij IDEA is slightly difficult. Review collected by and hosted on G2.com.

IntelliJ IDEA makes Java development much faster and more efficient. Its intelligent code completion, refactoring support, and debugging tools help catch issues early and reduce development time. I also like how well it integrates with Maven, Gradle, Git, Spring Boot, and databases, allowing me to work from a single IDE without constantly switching tools.

What I like best about IntelliJ IDEA is its smart code assistance and auto-completion, which helps me write code faster and with fewer mistakes. It also has strong debugging tools and makes it easy to navigate large projects. Overall, it improves productivity and makes development more efficient. Review collected by and hosted on G2.com.

What I dislike about IntelliJ IDEA is that it can feel heavy and slow on lower-spec computers, especially when opening large projects. It also uses a lot of memory, which can affect performance if multiple applications are running.
