Introduction to Junie CLI

Junie Cli
An LLM-agnostic coding agent built for real-world development — by JetBrains. Junie is an AI coding agent that lives in your terminal, integrates with your IDE and CI/CD pipelines, and helps you ship code faster. Give it a task in natural language — fix a bug, implement a feature, review a PR — and Junie handles the rest. Like your real coding buddy. Junie CLI Key Features:
  • AI coding agent in terminal
  • Multi-model (OpenAI, Anthropic, etc.)
  • Real-time interactive tasks
  • Deep codebase understanding
  • Plan mode (safe preview)
  • Command execution & automation
  • CI/CD & Git integration
  • Extensible (custom commands, MCP)

​
Step

1

Install Junie CLI

Firstly, install the newest LTS version of Node.js, and then use npm to install it globally in the terminal:
npm install -g @jetbrains/junie
2

Configure Junie CLI

Edit or create routerlink.json fileOn macOS & Linux: ~/.junie/models/routerlink.jsonOn Windows: C:\Users\<USERNAME>\.junie\models\routerlink.jsonMake sure to replace <ROUTERLINK_API_KEY> with your API key from RouterLink.
{
  "baseUrl": "https://router-link.world3.ai/api/v1/chat/completions",
  "id": "world3-router-north-america/anthropic/claude-sonnet-4.6",
  "apiKey": "<ROUTERLINK_API_KEY>",
  "apiType": "OpenAICompletion",
  "primaryModel": {
    "id": "world3-router-north-america/anthropic/claude-sonnet-4.6"
  },
  "fasterModel": {
    "id": "world3-router-north-america/anthropic/claude-sonnet-4.6"
  }
}
You can replace the “model” field with any model that is compatible with the OpenAI format.
