Copilot API

⚠️ EDUCATIONAL PURPOSE ONLY ⚠️ This project is a reverse-engineered implementation of the GitHub Copilot API created for educational purposes only. It is not officially supported by GitHub and should not be used in production environments.

Project Overview

A wrapper around GitHub Copilot API to make it OpenAI compatible, making it usable for other tools.

Demo

copilot-api-demo.mp4

Prerequisites

• Bun (>= 1.2.x)
• GitHub account with Copilot Individual subscription

Installation

To install dependencies, run:

bun install

Using with npx

You can run the project directly using npx:

npx copilot-api@latest

With options:

npx copilot-api --port 8080 --emulate-streaming

Running from Source

The project can be run from source in several ways:

Development Mode

bun run dev

Starts the server with hot reloading enabled, which automatically restarts the server when code changes are detected. This is ideal for development.

Production Mode

bun run start

Runs the server in production mode with hot reloading disabled. Use this for deployment or production environments.

Command Line Options

The server accepts several command line options:

Option	Description	Default
--help, -h	Show help message	false
--port, -p	Port to listen on	4141
--verbose, -v	Enable verbose logging	false
--log-file	File path for logging	-

Example with options:

bun run start --port 8080 --emulate-streaming

In all cases, the server will start and listen for API requests on the specified port.

Tested Tools Compatibility

Tool	Status	Notes
Aider	Full	Fully compatible
bolt.diy	Full	Fully compatible; use any random API key in UI if models fail to load
Page Assist	Full	Fully compatible
Kobold AI Lite	Full	Fully compatible

Note: In general, any application that uses the standard OpenAI-compatible /chat/completions and /models endpoints should work with this API.
