IntelliJ IDEA vs. VS Code for Java in 2025: Which IDE Should You Choose?
Walk into any Java shop in 2025 and you’ll see two editors on developers’ screens: IntelliJ IDEA and Visual Studio Code. The split is real. JetBrains’ own developer survey has consistently placed IntelliJ IDEA as the most-used IDE among Java developers, while Stack Overflow’s developer surveys show VS Code as the most popular editor overall across all languages—and climbing steadily among Java users too.
So which one should you pick? The honest answer is that it depends on what kind of Java work you do, how much you value out-of-the-box depth versus lightweight flexibility, and whether your team is willing to pay for tooling. Here’s a practical breakdown.
The Short Version
- IntelliJ IDEA is a purpose-built Java IDE. Its Ultimate edition is the stronger choice for enterprise Java, Spring, Jakarta EE, and large multi-module codebases.
- VS Code is a fast, extensible editor that handles Java surprisingly well through the Extension Pack for Java and, for serious work, the paid GitHub Copilot and Oracle Java extensions—though the deeper Java tooling increasingly comes from third parties.
- Cost matters: IntelliJ IDEA Community is free; Ultimate is a subscription. VS Code is free, but the best Java experience may involve paid add-ons.
IntelliJ IDEA: The Java-First Powerhouse
IntelliJ IDEA was designed around Java from day one, and it shows in ways that are hard to replicate with a general-purpose editor.
Refactoring and code intelligence
JetBrains’ static analysis engine understands Java semantics deeply. Rename refactorings, extract method, inline, change signature, and safe delete work reliably across large projects. The IDE’s inspections catch subtle issues—nullability problems, resource leaks, unused code—before they reach code review. For developers working in legacy codebases with hundreds of thousands of lines, this is often the deciding factor.
Framework support
IntelliJ IDEA Ultimate ships with first-class support for Spring, Spring Boot, Jakarta EE, Micronaut, Quarkus, and JPA/Hibernate. That means endpoint navigation from annotations, bean dependency diagrams, database schema inspection, and HTTP client tooling without installing anything. If you spend your day in Spring Boot, this integration alone can justify the subscription.
Built-in tooling
The IDE bundles a profiler, a database tool window, a terminal, a diff/merge tool, and a built-in HTTP client. Fewer context switches, fewer plugins to manage.
The catch
IntelliJ IDEA is heavier. It wants RAM (8 GB minimum is realistic; 16 GB is comfortable), and indexing a large project on first open takes time. The Community edition is genuinely capable for plain Java and JVM languages, but it lacks the framework and database support that many teams rely on. Ultimate pricing is per user per year, with discounts that improve after the first year—worth checking current JetBrains pricing rather than assuming last year’s numbers.
VS Code: Lightweight, Ubiquitous, Improving
VS Code started as a general editor and became a Java option through Microsoft’s Java extensions and the Language Support for Java extension built on the Eclipse JDT language server.
Speed and footprint
VS Code launches fast, uses less memory at idle, and feels responsive even on modest hardware. If you switch between Java, TypeScript, Python, and infrastructure files in the same day, having one editor for everything is a real workflow advantage.
The Java experience
With the Extension Pack for Java, you get code completion, debugging, Maven/Gradle support, test running, and project management. It’s solid for smaller services, scripting, and developers who touch Java occasionally. Spring Boot support exists through extensions but is less integrated than in IntelliJ Ultimate.
Where it falls short
Deep refactorings are less reliable. Large multi-module Maven or Gradle builds can strain the language server. Some advanced framework tooling requires paid extensions—notably, the official Java extension for VS Code from Oracle is a paid product, and GitHub Copilot is a separate subscription. The result is a capable but more assembled experience: you’re curating a toolchain rather than using one that was built for Java.
Head-to-Head Comparison
| Dimension | IntelliJ IDEA | VS Code |
|---|---|---|
| Java-first design | Yes | No (via extensions) |
| Refactoring depth | Excellent | Good but shallower |
| Spring/framework support | Built-in (Ultimate) | Extension-based |
| Startup and memory | Heavier | Lighter |
| Cost | Community free; Ultimate paid | Free; some add-ons paid |
| Multi-language workflow | Good | Excellent |
| Debugging | Excellent | Very good |
| Learning curve | Steeper | Gentler |
How to Decide
Choose IntelliJ IDEA if:
- You work primarily in Java, Kotlin, or Scala.
- Your projects are large, multi-module, or framework-heavy (Spring, Jakarta EE).
- You value refactoring safety and deep static analysis.
- Your employer covers the Ultimate license—many do, because the productivity gains are easy to justify.
Choose VS Code if:
- Java is one of several languages you use daily.
- You work on smaller services, scripts, or learning projects.
- You’re on constrained hardware or want fast startup.
- You’re comfortable assembling extensions and don’t need the deepest framework tooling.
A pragmatic middle path
Plenty of developers run both: IntelliJ IDEA for deep Java work and VS Code for quick edits, config files, and front-end code. There’s no rule requiring loyalty to one editor.
What’s Changing in 2025
Two trends matter. First, AI assistance is now table stakes in both tools—JetBrains bundles AI features into its ecosystem, and VS Code leans on GitHub Copilot. Second, the language server protocol has narrowed the gap: VS Code’s Java support keeps improving because the underlying JDT engine does. IntelliJ still leads on Java-specific depth, but the margin is narrower than it was five years ago.
The Takeaway
For dedicated Java development—especially enterprise, Spring-based, or large-scale codebases—IntelliJ IDEA remains the stronger choice in 2025, and Ultimate’s framework integration is hard to match. VS Code is the better fit for polyglot developers, lighter workflows, and teams that prefer a free, fast, extensible editor. Pick based on the work in front of you, not on popularity alone—and if you can, try both on your actual project for a week before committing.
