Providers

anylang is bring-your-own-key. It loads .env from the project where you run the CLI and uses the provider configured in anylang.config.json.

Recommended: OpenRouter

Use OpenRouter if you want one API key and the flexibility to choose from many models.

{
  "provider": {
    "name": "openrouter",
    "baseUrl": "https://openrouter.ai/api/v1",
    "model": "openai/gpt-4.1-mini"
  }
}

OPENROUTER_API_KEY=your-openrouter-key

You can change model to any OpenRouter model id supported by your account.

{
  "provider": {
    "name": "gemini",
    "model": "gemini-2.5-flash"
  }
}

GEMINI_API_KEY=your-provider-key

{
  "provider": {
    "name": "anthropic",
    "model": "claude-3-5-haiku-latest"
  }
}

ANTHROPIC_API_KEY=your-provider-key

Use openai-compatible with a custom baseUrl and model.

{
  "provider": {
    "name": "openai-compatible",
    "baseUrl": "https://your-gateway.example.com/v1",
    "model": "your-model"
  }
}

ANYLANG_API_KEY=your-provider-key

anylang does not include a hosted translation key, proxy requests, track usage, or store billing data.
