IntelliJ IDEA

IntelliJ IDEA is a leading IDE from JetBrains for professional Java and Kotlin development, running smoothly and stably on macOS.

Providing developers with deep intelligent code completion, intelligent refactoring, real-time error detection, and a seamless debugging experience. The software deeply integrates the latest AI models, supports Claude, GPT, Gemini, Grok, and native models, and enables natural language code generation, database querying, and refactoring operations through multi-agent experiences including Junie, Claude Agent, Codex, and GitHub Copilot and Cursor, which are compatible with the Agent Client Protocol. IntelliJ IDEA 2026.1 adds full support for Java 26, including pattern matching and latency constant preview capabilities, as well as Spring application runtime code insights to view bean injection, endpoint configuration, and environment status without pausing execution. Database tools natively integrate with AI chat to support natural language analysis and modify data structures. The intelligent editor provides unlimited code completion and next edit suggestions, combined with Git worktrees parallel branching, allowing developers to work efficiently throughout the design, development, testing, and deployment process. The software’s focus on code quality, reducing technical debt with powerful analyzers, and built-in Spring, Jakarta EE, web development, cloud deployment, and remote development capabilities help users stay ahead of the rapidly evolving technology frontiers. The interface is designed for comfort and smoothness, and macOS users enjoy native theme synchronization, quick startup, and a pleasant coding process, while privacy protection provides explicit consent options to ensure data security. IntelliJ IDEA, which is the go-to tool for building high-quality software with a focus on innovation rather than trivial tasks, is designed for code quality.
