The definitive IDE for JVM development, now featuring a 'Unified Distribution' where professional tools are unlocked via subscription. Known for its unparalleled static analysis and the new 'Junie' AI agent, it remains the gold standard for complex enterprise Java/Kotlin, though its heavy resource footprint and high cost drive hobbyists toward AI-first editors.

The premier specialized IDE for modern JavaScript and TypeScript. Following its 2025 transition to a free non-commercial license, it is now the top choice for hobbyists wanting pro-grade tools. The 2025.3 update introduces native Claude Agent integration, a high-performance service-powered TypeScript engine, and unified settings for Bun, Deno, and Node.js. It remains heavier than text editors but offers unmatched deep-code analysis and out-of-the-box refactoring.
