**An LLM-agnostic coding agent built for real-world development — by JetBrains.**

[Junie](https://github.com/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**

<Steps>
  <Step title="Install Junie CLI">
    <Tabs>
      <Tab title="CLI - Node.js">
        > Windows users may be unable to run scripts because of digital signature requirements. Please run the following command:\
        > **Windows PowerShell:**
        >
        > ```powershell theme={null}
        > Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy RemoteSigned -Force
        > ```

        Firstly, install [**the newest LTS version of Node.js**](https://nodejs.org/en/download/), and then use npm to install it globally in the terminal:

        ```shellscript theme={null}
        npm install -g @jetbrains/junie
        ```
      </Tab>

      <Tab title="CLI - Native Install">
        **macOS, Linux:**

        ```shellscript theme={null}
        curl -fsSL https://junie.jetbrains.com/install.sh | bash
        ```

        **Windows PowerShell:**

        ```powershell theme={null}
        powershell -NoProfile -ExecutionPolicy Bypass -Command "iex (irm 'https://junie.jetbrains.com/install.ps1')"
        ```
      </Tab>
    </Tabs>
  </Step>

  <Step title="Configure Junie CLI">
    **Edit or create** `routerlink.json` file

    On macOS & Linux: `~/.junie/models/routerlink.json`

    On Windows: `C:\Users\<USERNAME>\.junie\models\routerlink.json`

    Make sure to replace `<ROUTERLINK_API_KEY>` with your API key from [RouterLink](https://routerlink.ai/settings/api-keys). When replacing it, do not keep the angle brackets `<` and `>`.

    ```json theme={null}
    {
      "baseUrl": "https://router-link.world3.ai/api/v1/chat/completions",
      "id": "claude-sonnet-4-6",
      "apiKey": "<ROUTERLINK_API_KEY>",
      "apiType": "OpenAICompletion",
      "primaryModel": {
        "id": "claude-sonnet-4-6"
      },
      "fasterModel": {
        "id": "claude-sonnet-4-6"
      }
    }
    ```

    You can replace the “id” field with any [**model**](https://routerlink.ai/models) that is compatible with the OpenAI format:

  <Step title="First launch">
    > Windows users may encounter issues running the software due to missing VC runtime libraries. Please download and install [this software](https://aka.ms/vs/17/release/vc_redist.x64.exe).

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

    ```shellscript theme={null}
    junie --model custom:routerlink
    ```

    Now you can use Junie.
