GPT Engineer is a command-line tool for trying out AI-powered code generation, letting you describe what you want and have a model produce the code. It was the forerunner of the Lovable product.

The GitHub repository has been archived and is now read-only, but it has a huge following and remains a useful reference for anyone curious about how AI coding tools work. The code is free to download and explore.
