## What it is
A reverse-engineered proxy that exposes the GitHub Copilot API as OpenAI and Anthropic compatible endpoints, letting any OpenAI/Anthropic-compatible tool use Copilot as its LLM backend. It includes a usage dashboard, rate limiting, and one-flag Claude Code integration.

## Use cases
- use github copilot subscription with claude code
- expose copilot as an openai-compatible api server
- point any openai sdk tool at github copilot
- monitor copilot api usage and quotas
- add rate limiting to copilot requests
- use copilot with anthropic messages api clients

## When to choose
- you have a GitHub Copilot subscription and want to reuse it in OpenAI/Anthropic-compatible tools like Claude Code
- you need a usage dashboard and rate-limit controls for Copilot requests

## When to avoid
- you use opencode, which supports Copilot natively without a proxy
- you need a stable, officially supported API - this is reverse-engineered and may break or trigger GitHub abuse detection
- you don't have an active GitHub Copilot subscription
