Free GPT-4/5 via Reverse-Engineered Copilot
A Python tool that turns Microsoft Copilot into a local OpenAI-compatible API — GPT-4 and GPT-5 access with no billing and no API keys required.
A Python library and local FastAPI server that wraps Microsoft Copilot's web interface into an OpenAI-compatible REST API, giving access to GPT-4 and GPT-5 without an OpenAI account or any payment. It handles Cloudflare challenges, rate limits, and comes with Docker support. Picking up 408 stars in four days shows just how hungry people are for free model access.
Why a vibe-coder should care
Any tool that speaks OpenAI — your IDE extension, your script, your vibe-coding agent — can be pointed at this local server instead of the real API. It's not built for heavy production, but for experimenting, prototyping, or simply not paying for every token while you're learning.
