IntelliJ IDEA 2026.1 brings built-in support for more AI agents, including Codex, Cursor, and any ACP-compatible agent, and delivers targeted, first-class improvements for Java, Kotlin, and Spring. The release also advances IntelliJ IDEA’s mission to provide support for the latest languages and tools from day one.
Any agent, built-in:
- ACP Registry: Browse and install AI agents in one click.
- Git worktrees: Work in parallel branches and hand one off to an agent while you keep moving in another.
- Database access for AI agents: Let Codex or Claude Agent query and modify your data sources natively.
Intelligence in the platform:
- Quota-free next edit suggestions: Propagate changes throughout a given file with IDE-driven assistance.
- Spring runtime insight: Inspect injected beans, endpoint security, and property values without pausing execution.
- Kotlin-aware JPA: Detect and fix Kotlin-specific pitfalls in Jakarta Persistence entities.
First-class language support:
- Java 26: Enjoy day-one support, including preview features.
- Kotlin 2.3.20: Enjoy day-one support, including experimental features.
- C/C++ in IntelliJ IDEA: Access first-class C/C++ coding assistance for multi-language projects.
- Support for JavaScript without an Ultimate subscription.
Productivity and environment:
- Expanded command completion, now with AI actions, postfix templates, and config file support.
- Better performance for large-scale TypeScript projects.
- Native Dev Container workflow: Open containerized projects as if they were local.
Along with new features, 2026.1 delivers numerous stability, performance, and usability improvements across the platform. These are described in a separate What’s Fixed blog post.
