JetBrains Junie
JetBrains Junie is a coding agent for work in JetBrains IDEs, a terminal, or headless CI/CD scripts. It offers chat assistance, codebase indexing, terminal access, and agent mode. Advanced Plan Mode lays out requirements, design, and delivery stages before code changes; plans can be edited and committed in.junie/plans. Users can review key actions, and the CLI requests approval for sensitive actions unless brave mode is enabled or an action is allowed. Junie supports models from OpenAI, Anthropic, Google, and xAI, while the CLI can use provider API keys directly. Remote Control lets users monitor asynchronous CLI runs in a web app. Project guidelines, Agent Skills packages, and slash commands shared across CLI and IDE through ACP are also supported. The IDE plugin works with listed JetBrains IDEs and Android Studio. The CLI runs on Linux, macOS, and Windows, though sandbox mode is limited to macOS and Linux. Free to Start is free with five AI credits; paid plans start at $8.33 a month per user.
