OpenProxy

中文 | English

Note

Designed by humans, developed by Gemini 3, not widely tested.

OpenProxy is a lightweight, zero-config gateway designed for Claude Code and Gemini CLI, enabling them to use OpenAI-Compatible APIs.

Features

• Dual Client Support: One service supports both Claude Code and Gemini CLI.
• Zero Server-Side Config: No server-side configuration required; all settings are controlled by the original client.
• Multi-User Support: Stateless design allows multiple users to use their own API Keys.
• Worker Deployment: Supports deployment to Cloudflare Workers and Vercel.
