The Ultimate IDE for Professional Development with Minor Memory Hiccups **Rating:** 4.5/5.0 stars **Reviewed by:** Siddique K. | LLM Data Trainer Specialist, Computer Software, Small-Business (50 or fewer emp.) **Reviewed Date:** March 15, 2026 **What do you like best about IntelliJ IDEA?** I use IntelliJ IDEA for TypeScript, Node.js, and NestJS development and find it incredibly useful for building modular backend APIs, REST services, and full-stack applications. It smartly combines code completion, Git, Docker, and database tools in one place, which solves context-switching overhead for me. I really appreciate its ability to catch TypeScript errors early and make refactoring across large codebases fast and reliable. The intelligent code completion and deep TypeScript support are standout features for me, saving a lot of time, especially on complex projects. It reduces the time I spend looking up syntax or API references and auto-suggests the correct imports and method signatures instantly. Additionally, the TypeScript support helps catch type errors before runtime, which is critical for production-grade AI pipelines. I find the initial setup straightforward as well, with plugin installations taking only a few minutes. **What do you dislike about IntelliJ IDEA?** The biggest drawback is high memory consumption. Running IntelliJ alongside Docker containers, a local PostgreSQL instance, and a Node.js dev server can push RAM usage significantly, causing occasional slowdowns. The initial project indexing also takes too long on large monorepos. A lighter memory footprint would make it a near-perfect tool. **What problems is IntelliJ IDEA solving and how is that benefiting you?** IntelliJ IDEA reduces context-switching by combining tools like Git and Docker. It ensures early TypeScript error detection and accelerates refactoring across large codebases. Its intelligent code completion saves time by auto-suggesting correct imports and method signatures, particularly for complex NestJS projects. ### 29.

Powerful Productivity Boost, but Heavy on Resources and Can Feel Slow **Rating:** 3.0/5.0 stars **Reviewed by:** Mokhinur A. | Software Engineer, Mid-Market (51-1000 emp.) **Reviewed Date:** February 18, 2026 **What do you like best about IntelliJ IDEA?** 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. **What do you dislike about IntelliJ IDEA?** 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. **What problems is IntelliJ IDEA solving and how is that benefiting you?** For me, IntelliJ IDEA mainly solves the problem of dealing with complex projects without getting lost. When a codebase grows, it becomes hard to remember where everything is and how different parts are connected. IntelliJ makes it easy to navigate between classes and methods, and I can quickly find usages or references without manually searching through files. It also helps me avoid small but annoying mistakes. I like that it highlights errors immediately while I’m typing. Instead of running the program and then fixing issues, I can correct things on the spot. That saves a lot of time. Another big benefit is having everything in one place. I can manage Git, run builds, debug, and even check databases without switching between tools. It keeps my workflow more organized. Overall, it makes development feel more structured and less stressful, especially when working on larger or long-term projects. ### 41.
