Quickstart

Step 1: Install Junie CLI

In the terminal or command prompt of your choice, run:

Step 2: Start Junie in your project

Navigate to the root directory of the project where you want to use Junie CLI and run junie:

Step 3: Authenticate

On the Junie welcome screen, select one of the available authentication options:

• Log in with your JetBrains Account

  Use Junie CLI as part of your subscription plan with JetBrains. When selecting this option, you'll be redirected to the JetBrains Junie login page in your browser.

• Use JUNIE_API_KEY

  Run Junie CLI with usage-based billing. When selecting this option, you'll be prompted to provide an access token. To generate your JUNIE_API_KEY access token, go to junie.jetbrains.com/cli.

• Bring Your Own Key (BYOK)

  Use your own API keys or OAuth tokens from Anthropic, OpenAI, Google, or other third-party LLM providers. Junie CLI uses these API keys to send requests to LLMs directly without requiring a JetBrains AI subscription.

  BYOK can be used on its own or together with JetBrains Account authorization or Junie API key. If a model is available through both the BYOK API key and JetBrains AI subscription, the requests are billed to your BYOK provider directly.

Step 4: Type your prompt

Type the prompt in the interactive CLI, for example:

Use @ to attach a file or folder from the current project to the request context. To see the list of available slash commands and use them, type /.
