Junie

Install Junie CLI with a one-line script on macOS, Linux or Windows, or via Homebrew or npm, then run junie in your project. On the welcome screen you choose how usage is paid: your JetBrains subscription, a Junie API key for usage-based billing, your own provider keys, or a self-hosted endpoint such as Ollama or LM Studio.

Then type a task. Reference files with @, drag in screenshots or design specs, and run shell commands with !.

• •Bring Any Model - More than ten models through your own keys, including Claude, Gemini, GPT and Grok, plus custom endpoints.
• •Advanced Plan Mode - A structured plan you approve or redirect before any code changes, stored as editable, committable files, with planning and implementation on different models to save tokens.
• •Agentic Debugging - Junie can start a debugger, set breakpoints, inspect stack frames and evaluate expressions, including in compiled .class files and JARs on the JVM, autonomously or with your help.
• •Live Prompting and Human in the Loop - Steer the agent mid-task and approve key actions as it works, with a dynamic allowlist for trusted commands.
• •Remote and Parallel Work - Start a migration from your laptop, check progress from your phone and review the pull request later.

Junie fits developers who already work in JetBrains IDEs such as IntelliJ IDEA, PyCharm, WebStorm, GoLand, Rider or Android Studio and want an agent that uses the same code intelligence. JVM teams get particular value from agentic debugging.

It also suits developers who care about cost and model choice: start free with Junie Lite, run entirely on your own keys at provider rates, or use a local model.
