Use CC Switch with llmrelay

Setup

1. 1 Install CC Switch and select the Claude Code tab in the main window.
2. 2 Click the + button to open the Add Provider panel and pick the Custom preset.
3. 3 In the JSON editor, set env.ANTHROPIC_BASE_URL to https://api.llmrelay.dev and env.ANTHROPIC_AUTH_TOKEN to your relay key.
4. 4 Click Add to save, then select the provider and click Enable (or pick it from the tray menu).
5. 5 Claude Code hot-switches without a restart; other tools need a terminal restart.

Config

// CC Switch "Custom" provider JSON for Claude Code
// CC Switch writes this env block into ~/.claude/settings.json when you enable the provider
{
  "env": {
    "ANTHROPIC_BASE_URL": "https://api.llmrelay.dev",
    "ANTHROPIC_AUTH_TOKEN": "***"
  }
}

Smoke test

Copy, paste, run. If you get JSON back with a message, you're good.

In the provider editor click the endpoint test button (CC Switch calls the OpenAI-compatible /v1/models endpoint with your key), then run `claude` in a terminal and send one prompt.

Gotchas

• !Provider data is stored in a SQLite database at ~/.cc-switch/cc-switch.db, not a plain JSON file; edit through the app, not by hand.
• !Only Claude Code hot-switches. For Codex/Gemini/OpenCode/Hermes you must restart the terminal or CLI after switching.
• !If your relay needs a non-standard path, enable Advanced Options -> Full URL Mode and paste the complete endpoint instead of a prefix; otherwise CC Switch appends fixed paths like /v1/chat/completions.
