How to Switch Claude Code to Crazyrouter: Base URL, Setup, and Model Routing

If you use AI coding agents like Claude Code, OpenAI Codex, or Gemini CLI, you know the pain of managing API keys, base URLs, and config files across multiple tools. CC-Switch solves this with a single desktop app — and Crazyrouter is a fully supported provider out of the box.

What is CC-Switch?#

CC-Switch is an open-source desktop application (18,000+ stars on GitHub) built with Tauri 2 that lets you manage all your AI CLI coding agents from one place:

• Claude Code — Anthropic's terminal AI assistant
• OpenAI Codex — OpenAI's coding agent
• Gemini CLI — Google's command-line AI tool
• OpenCode — Open-source AI coding assistant

Instead of manually editing ~/.claude/settings.json, ~/.codex/auth.json, or ~/.gemini/.env every time you want to switch providers, CC-Switch gives you a clean GUI with one-click switching.

Why Use Crazyrouter with CC-Switch?#

Crazyrouter provides unified API access to 300+ AI models through a single endpoint. When paired with CC-Switch, you get:

Step 3: Configure Models (Optional)#

CC-Switch supports granular model configuration with 4 tiers:

• Haiku tier — Fast, lightweight models (e.g., claude-sonnet-4-20250514)
• Sonnet tier — Balanced performance (e.g., claude-sonnet-4-20250514)
• Opus tier — Maximum capability (e.g., claude-opus-4-20250514)
• Custom — Any model available on Crazyrouter

Since Crazyrouter supports 300+ models, you can configure any combination across tiers.

Step 4: Switch with One Click#

Once configured, switching to Crazyrouter is instant:

• From the app: Click the Crazyrouter entry in your provider list
• From system tray: Right-click the CC-Switch icon → select Crazyrouter
• Via deep link: Use ccswitch:// protocol links for one-click import

CC-Switch automatically updates the config files for whichever AI tools you have installed.

MCP Server Management#

CC-Switch also provides a unified panel for managing MCP (Model Context Protocol) servers across all your AI tools. This means you can:

• Add MCP servers once and sync them to Claude Code, Codex, and Gemini CLI
• Toggle servers on/off per tool
• Import/export MCP configurations
• Use built-in templates for common servers (filesystem, fetch, etc.)

This works seamlessly with Crazyrouter since MCP server configuration is independent of your API provider.

Speed Testing#

CC-Switch includes a built-in speed test feature. You can measure the latency of your Crazyrouter endpoint compared to other providers, helping you choose the fastest option for your region.
