What is Claude Code Router?
Claude Code Router is an open-source Node.js CLI tool that revolutionizes AI-assisted coding by extending Anthropic's Claude Code with powerful multi-model routing capabilities. This advanced AI coding infrastructure enables developers to seamlessly route coding requests across various large language models from providers like OpenRouter, DeepSeek, Ollama, Google Gemini, and Volcengine. Whether you're optimizing for cost efficiency, specialized reasoning tasks, or handling large codebases, Claude Code Router delivers unparalleled flexibility and control over your AI coding workflow.
How to Use Claude Code Router
Claude Code Router offers intuitive setup that gets you started in minutes. First, ensure Node.js and npm are installed on your system. Install Anthropic's Claude Code CLI with npm install -g @anthropic-ai/claude-code, then add the router using npm install -g @musistudio/claude-code-router. Launch your enhanced coding environment by running ccr code, and you're ready to experience multi-model AI coding assistance.
Master Claude Code Router's advanced capabilities by configuring the ~/.claude-code-router/config.json file. Define custom routing rules, API keys, available models, and specialized roles for different tasks. Switch models dynamically during runtime using the /model provider,model command, allowing you to optimize your AI assistant for specific coding challenges on the fly.
Key Features of Claude Code Router
- Multi-Model Routing: Access any configured LLM provider or model with intelligent request routing and dynamic switching capabilities. Route queries to the most appropriate AI model based on task complexity, context length, or cost considerations.
- Specialized Model Roles: Designate specific models for background tasks, high-reasoning operations (think mode), and long-context handling. Optimize performance by matching model capabilities to task requirements automatically.
- Flexible Configuration System: Fully customizable JSON-based configuration allows precise control over providers, routing rules, API endpoints, and model behaviors. Tailor your AI coding infrastructure to match your exact workflow needs.
- Cost Optimization Engine: Significantly reduce AI coding expenses by routing routine tasks to cost-effective models while reserving powerful models for complex reasoning challenges. Maximize value without compromising quality.
- Extensible Architecture: Seamlessly integrate with image processing tools, web-search capabilities, detailed logging systems, and GitHub Actions for automated code reviews and CI/CD workflows.
Each feature is designed to enhance developer productivity, reduce operational costs, and provide unprecedented control over AI-assisted coding workflows. Featured on aitop-tools.com as a cutting-edge solution for modern development teams.

Frequently Asked Questions About Claude Code Router
What is the main purpose of Claude Code Router?
Claude Code Router extends Anthropic's Claude Code CLI to enable multi-model routing across various LLM providers. Its primary purpose is providing developers with flexible, cost-effective AI coding assistance by allowing dynamic selection of the most appropriate model for each specific task, whether that's background processing, complex reasoning, or long-context analysis.
How does Claude Code Router differ from Claude Code?
While Claude Code Router builds upon Anthropic's official Claude Code CLI, it adds powerful multi-provider routing capabilities, specialized model role assignments, and extensive customization options through JSON configuration. Claude Code Router enables cost optimization and dynamic model switching that the standard Claude Code CLI doesn't offer.
Which AI models and providers does Claude Code Router support?
Claude Code Router supports multiple leading LLM providers including OpenRouter, DeepSeek, Ollama, Google Gemini, and Volcengine. The extensible architecture allows integration with additional providers through the flexible configuration system, giving developers access to dozens of AI models from a single interface.
How is Claude Code Router configured?
Claude Code Router uses a JSON configuration file located at ~/.claude-code-router/config.json. This file defines API keys, base URLs, available models, and specific roles (default, background, think, longContext) for each provider. The intuitive configuration structure makes it easy to add new providers or adjust routing rules without modifying code.
Can I switch models dynamically while using Claude Code Router?
Yes, Claude Code Router supports real-time model switching using the /model provider,model command during active coding sessions. This allows developers to optimize AI assistance on the fly, switching to more powerful models for complex problems or economical models for routine tasks without restarting the CLI.
