CrazyrouterCC-Switch + Crazyrouter: Claude Code Base URL Setup Guide
Set up Crazyrouter in CC-Switch for Claude Code-style workflows, with base URL notes, model routing tips, and compatibility caveats for current tool versions.
If you use AI coding agents like Claude Code, OpenAI Codex, Gemini CLI, or OpenCode, you know the pain of managing API keys, base URLs, and config files across multiple tools. CC-Switch is a third-party desktop app that can help manage those local settings. Crazyrouter can be added as a unified API endpoint, but compatibility depends on the installed tool version and the config fields that tool currently supports.
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 files such as ~/.claude/settings.json, ~/.codex/auth.json, or ~/.gemini/.env, CC-Switch gives you a GUI for switching supported provider settings. Always confirm the generated config against the current documentation for Claude Code, Codex, Gemini CLI, or OpenCode before relying on it in production.
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:
| Feature | Benefit |
|---|---|
| One API key for everything | Access Claude, GPT, Gemini, and more without separate accounts |
| Faster switching | Switch supported provider profiles from the app or system tray |
| Automatic config sync | CC-Switch writes the correct config files for each tool |
| Cost savings | Competitive pricing with pay-as-you-go billing |
| 30% first top-up bonus | Exclusive for CC-Switch users (details below) |
Setup Guide#
Step 1: Install CC-Switch#
Download CC-Switch for your platform:
- Windows: MSI installer or portable ZIP from GitHub Releases
- macOS:
brew install --cask farion1231/tap/cc-switch - Linux: DEB, RPM, AppImage, or Flatpak available
Step 2: Add Crazyrouter as a Provider#
- Open CC-Switch
- Click "Add Provider"
- Fill in the configuration:
| Field | Value |
|---|---|
| Name | Crazyrouter |
| API Base URL | https://crazyrouter.com |
| API Key | Your Crazyrouter API token (starts with sk-) |

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 should only take a few clicks:
- 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 is usually independent of your API provider, but check each coding tool's current MCP support before assuming every server syncs across every client.
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.
Exclusive CC-Switch Bonus#
If the CC-Switch referral promotion is still active, users who sign up for Crazyrouter through CC-Switch may get a 30% bonus on their first top-up:
- Register at crazyrouter.com/register?ref=cc-switch
- Use redemption code CCSWITCH on your first top-up
- Confirm the promotion on the checkout or account page before topping up
For example, a 30% active promotion would turn a 13 in credits, but promotion rules can change.
