About

Junie is JetBrains' AI coding agent for planning and executing complex software tasks. It can break work into steps, modify code across files, run terminal commands and tests, use external tools, and report progress while keeping developers in control. Junie works inside supported JetBrains IDEs and through its interactive CLI on Linux, macOS, and Windows. It can use project and IDE context, supports Ask and Code modes, and can roll back changes after an agent task. GitHub Actions and GitLab CI/CD integrations extend Junie into repository workflows. The agent supports multiple major model providers and offers Bring Your Own Key through the CLI, including OpenAI, Anthropic, Google, xAI, OpenRouter, and GitHub Copilot. Custom or self-hosted endpoints can also be connected through supported CLI configurations, while Agent Skills let teams package reusable instructions, scripts, and reference materials. Junie is aimed at developers and teams delegating multi-step coding work such as implementation, refactoring, debugging, migrations, testing, and code review. JetBrains also offers Junie Local for supported hardware, where the agent and model run locally without cloud credits or network dependency.
