The Power of IntelliJ IDEA Wherever You Code

IntelliJ IDEA

The Java and Kotlin IDE for you and your agents

Download IntelliJ IDEA

Free – with 30 days of Ultimate included

One place to run agents and verify their work,
with jetbrains air

Configure how you work

Choose how each agent launches, in the GUI or the terminal, and what the IDE keeps front and center – your code or the agent session.

Move in parallel without losing context

Work with multiple agents at once, in one project or across several, without re-explaining state or codebase context.

Keep track of every session

See which sessions are currently running, done, or waiting on you. Comment on a line in the diff and send it back to the agent to act on.

Review and verify changes

Debugging, testing, profiling, and database tools are all one click away, so you can confirm that nothing breaks before you merge the change.

Deterministic tools for you and your agents

IntelliJ IDEA’s code intelligence resolves every usage, dependency, and type across the codebase. That way, your agents use fewer tokens and make fewer wrong turns. When a tricky problem requires your judgment, the same tools help you work it out faster and change the code safely.

Refactoring: one rename, every reference

Task: rename a method used across 100 files

Agent without IDE intelligence

  1. grep text matches
  2. edit 100 files
  3. Build failsmissed usages

fix → rebuild → repeat

105tool calls

Agent with IDE intelligence

  1. find symbol
  2. safe rename
  3. Doneevery reference updated

2tool calls

Illustrative example. Tool call counts include discovery, edits, and builds.

Your agents, your models, your subscriptions

Connect the agents you use and run them on your own API key, the subscription you already pay for, or JetBrains AI. Switch subscriptions anytime, even during a session.

Your whole stack, one IDE

  • Develop confidently with AI

    Generating code quickly with AI is the easy part. Trusting the result is harder. IntelliJ IDEA closes the loop: Generate with AI, and then validate immediately with a debugger, test runner, and built-in inspections. Ship with confidence, not just speed.

  • Professional Java and Kotlin development – from day one

    Get industry-leading support for Java and Kotlin, plus first-class Spring integration developed in close collaboration with the Spring Framework team, and deep support for other modern frameworks and technologies your applications rely on, including Jakarta EE, Micronaut, and Quarkus.

  • Deep code understanding everywhere in your project

    Work confidently with an IDE that understands your application in depth, with intelligent navigation, accurate refactorings, advanced inspections, and reliable debugging throughout your codebase.

  • All the tools you need, built in

    Everything you need is already part of IntelliJ IDEA. Work with databases, test APIs, profile applications, and more without leaving the IDE. Deeply integrated tools keep you focused, eliminate context switching, and streamline your entire workflow.

Customer Stories

Yasuaki Kato

Software Engineer at a healthcare and senior care technology company

“The reason we use IntelliJ IDEA is because we believe it is the most efficient choice for development.”

Jay

Backend Engineer at a company building software for self-service photo studios

“Git integration enables partial commits, branch comparisons, and rebasing within the IDE. For large-scale codebases, class diagrams and dependency analysis provide a clear view of structure and impact. When needed, tuning indexing and build caches improves speed even further."

Varij Kapil

A former Software Developer at a company building custom IT and cloud solutions

“Breaking changes and refactoring need to happen in multiple Java modules and React components. Making such huge changes would not have been possible without JetBrains products.”

Phan Manh Hung

CIO at a company building digital infrastructure for healthcare

“In healthcare software, the most expensive line of code is often the one nobody felt safe to refactor. Our team uses [...] IntelliJ IDEA for the Java/Spring Boot core of [our Health Platform], where you refactor carefully because the rules governing patient data don't move.”
