VS Code vs IntelliJ IDEA vs Cursor: IDEs Compared

VS Code is a lightweight editor, IntelliJ IDEA is a full-featured IDE, and Cursor is an AI-first editor — three tools for writing code in 2026.

At a Glance

Key Differences

• Philosophy: VS Code is an editor that becomes an IDE through extensions — you assemble your toolchain from a marketplace of 40,000+ extensions. IntelliJ IDEA is a complete IDE that ships with a built-in compiler, debugger, profiler, and static analysis — everything works out of the box. Cursor is VS Code with AI deeply woven into the editing experience — inline code generation, multi-file editing, and a chat interface that understands your whole codebase.
• Refactoring: IntelliJ IDEA’s refactoring tools are the gold standard — rename across files with preview, extract method/variable/interface, change signature, and language-specific refactorings like “Convert to Kotlin.” VS Code and Cursor rely on basic text manipulation and language server capabilities. For large-scale refactoring in Java, C#, or Kotlin, IntelliJ saves hours.
• AI Integration: Cursor leads here — its AI understands your codebase context (open files, project structure, terminal output) and can edit multiple files in one operation. VS Code needs the Copilot extension for AI features. IntelliJ IDEA has JetBrains AI Assistant but it’s less integrated than Cursor’s model.
• Performance: VS Code and Cursor are snappy — they start in seconds and use reasonable memory. IntelliJ IDEA is heavier — it indexes your project on load, which takes time and memory, but this indexing powers its superior code navigation (find usages, type hierarchy, call hierarchy).

When to Choose VS Code

Choose VS Code when you want a fast, extensible editor that handles any language. VS Code is the most popular developer tool in 2026 — its extension ecosystem covers everything from Docker and Kubernetes to Jupyter notebooks and remote development over SSH. VS Code’s remote development feature lets you open folders in WSL, containers, or SSH hosts seamlessly. VS Code is ideal for frontend developers, Python developers, and anyone who works across multiple languages and wants a consistent experience.

When to Choose IntelliJ IDEA

Choose IntelliJ IDEA Ultimate when you work primarily with Java, Kotlin, or enterprise frameworks (Spring, Jakarta EE). IntelliJ’s deep framework understanding — autocomplete for Spring beans, navigation through JPA entities, and built-in HTTP client — makes it indispensable for backend development. IntelliJ’s debugger, profiler, and test runner are best-in-class. The Community Edition is free and excellent for Java, Kotlin, and Android development. Teams working on large Java/Kotlin codebases should pick IntelliJ.

When to Choose Cursor

Choose Cursor when AI-assisted development is central to your workflow. Cursor’s built-in AI can generate entire functions from comments, refactor code across multiple files, and explain complex code in natural language. Cursor is a fork of VS Code, so all VS Code extensions work. For developers who use AI daily — prototyping, code generation, bug fixing — Cursor’s tight integration delivers a step-change in productivity. At DodaTech, Cursor is the preferred editor for frontend development of Doda Browser.

Side by Side Code Example: Refactor a Java Class

VS Code

// VS Code: manual extract method using selection
// Select the println lines → right-click → "Refactor... → Extract Method"
// Or use the Copilot inline suggestion
public class Order {
    private double total;
    private String customer;

    public void printInvoice() {
        System.out.println("Customer: " + customer);
        System.out.println("Total: $" + total);
        // Manually select and extract
    }
}

IntelliJ IDEA

// IntelliJ: select lines → Ctrl+Alt+M → name the method
// IDE renames, updates callers, shows preview
public class Order {
    private double total;
    private String customer;

    public void printInvoice() {
        printLine("Customer: " + customer);
        printLine("Total: $" + total);
    }

    // IntelliJ automatically created this method
    private void printLine(String line) {
        System.out.println(line);
    }
}

Cursor

// Cursor: highlight lines → Ctrl+K → type "extract to method"
// AI refactors the code inline
public class Order {
    private double total;
    private String customer;

    public void printInvoice() {
        printInvoiceDetails();
    }

    // Cursor AI generated this method
    private void printInvoiceDetails() {
        System.out.println("Customer: " + customer);
        System.out.println("Total: $" + total);
    }
}

All three produce the same result — extracting a method — but the approach differs. IntelliJ gives you precise control with preview. Cursor interprets natural language. VS Code offers basic refactoring via the language server.
