OpenAI-Compatible Endpoint for Free Models: Point opencode, Cursor and Scripts at It

OpenAI-Compatible Endpoint for Free Models

Most AI coding tools (opencode, Cursor, and dozens of libraries) speak the OpenAI API. What if you could point all of them at free models?

The idea

Run a tiny local proxy that speaks OpenAI's chat/completions protocol, and behind it rotate free model providers. Every tool that understands OpenAI just works.

FreeGate

FreeGate is exactly that. Install it, and in your tool's config point baseURL at http://localhost:4000/v1.

Example: opencode

{
  "provider": {
    "free-proxy": {
      "npm": "@ai-sdk/openai-compatible",
      "options": { "baseURL": "http://localhost:4000/v1", "apiKey": "your-key" }
    }
  }
}

What you get

• Free tier-S models behind your favorite tools
• Automatic failover
• A dashboard with usage
