JetBrains IDE Setup Guide

Configure IntelliJ IDEA, PyCharm, WebStorm, or any JetBrains IDE to use KorProxy

1Overview

JetBrains IDEs (IntelliJ IDEA, PyCharm, WebStorm, GoLand, etc.) can integrate AI assistants through the Continue plugin.

KorProxy lets you use your own AI subscriptions (Claude Pro, ChatGPT Plus, Google AI) instead of paying for additional API credits. The Continue plugin connects to KorProxy's OpenAI-compatible endpoint.

This guide covers setup via Continue. For general Continue configuration, see the Continue guide.

2Prerequisites

  • KorProxy app installed and running
  • JetBrains IDE installed (IntelliJ, PyCharm, WebStorm, etc.)
  • At least one provider authenticated in KorProxy

3Configuration Steps

Step 1: Install Continue Plugin

  • Open Settings → Plugins
  • Search for "Continue" in the Marketplace
  • Click Install and restart the IDE

Step 2: Configure Continue

Edit the Continue configuration file at ~/.continue/config.json:

{
  "models": [
    {
      "title": "Claude via KorProxy",
      "provider": "openai",
      "model": "claude-sonnet-4-5-20250929",
      "apiBase": "http://localhost:1337/v1",
      "apiKey": "korproxy"
    }
  ]
}

Step 3: API Key

  • The apiKey can be any string (e.g., korproxy)
  • KorProxy handles authentication via OAuth—the API key is just a placeholder

Alternative: HTTP Proxy Settings

For tools that don't support custom base URLs, you can configure the IDE's HTTP proxy:

  • Go to Settings → Appearance & Behavior → System Settings → HTTP Proxy
  • Select Manual proxy configuration
  • Set HTTP proxy to localhost port 1337

5Troubleshooting

Common Issues

  • 1

    Connection refused

    Check that KorProxy is running—look for the status indicator in the menu bar

  • 2

    Authentication errors

    Verify the provider is authenticated in KorProxy for the model you're using

  • 3

    Continue plugin not loading

    Ensure you're using a compatible JetBrains IDE version and restart after installation

  • 4

    Config file not found

    Open Continue once to generate the default config, then edit ~/.continue/config.json
