Copilot API Proxy

A FAST reverse proxy server written in Go that forwards /v1/chat/completions requests to the GitHub Copilot API, to expose the Copilot API to other tools

Warning

This is a reverse-engineered proxy of GitHub Copilot API. It is not supported by GitHub, and may break unexpectedly. Use at your own risk.

Warning

GitHub Security Notice: Excessive automated or scripted use of Copilot (including rapid or bulk requests, such as via automated tools) may trigger GitHub's abuse-detection systems. You may receive a warning from GitHub Security, and further anomalous activity could result in temporary suspension of your Copilot access.

GitHub prohibits use of their servers for excessive automated bulk activity or any activity that places undue burden on their infrastructure.

Please review:

• GitHub Acceptable Use Policies
• GitHub Copilot Terms

Use this proxy responsibly to avoid account restrictions.
