Use your Claude or ChatGPT subscription inside VS Code or other IDEs that expect an OpenAI-compatible API key.
Spread requests across multiple accounts of the same service to avoid hitting rate limits.
Access Gemini, Claude, and ChatGPT models through a single unified endpoint without paying for separate API tiers.
Build custom tools or scripts that need to call different AI models without managing multiple authentication methods.
Requires API keys for Claude, ChatGPT, and/or Gemini to be functional; Go binary compilation needed if not pre-built.
CLIProxyAPI is a local proxy server that lets you use AI coding tools like Gemini CLI, Claude Code, and OpenAI Codex through a standardized API interface, without needing separate API keys for each service. Instead, it wraps your existing paid subscriptions (the ones you already log into via a web browser) and exposes them as if they were a single unified API endpoint that many AI tools and apps already know how to talk to. The problem it solves is fragmentation. Developers often have subscriptions to multiple AI services but want to use them through a single tool or coding assistant. CLIProxyAPI acts as a middleman: you log in to your accounts once, and then any app that supports the standard OpenAI or Gemini API format can route requests through CLIProxyAPI to whichever underlying model you want. It handles the full range of response types, streaming (where text appears word by word), non-streaming (full response at once), and function-calling (where the AI can invoke tools on your behalf). It also supports multiple accounts per service with round-robin load balancing, meaning it cycles through accounts automatically to spread usage. Someone would use this when they already pay for Claude, ChatGPT, or Gemini subscriptions and want to unlock those models inside coding environments or apps that only accept an API key format. Rather than paying again for API access on top of subscription costs, CLIProxyAPI bridges the gap. The project is written in Go, which makes it fast and easy to run as a self-hosted binary on your own machine or server.
