Full story

Simon Willison has created an experimental web component called 'github-code' that allows developers to embed GitHub code snippets directly into web pages. The tool uses GPT-5.5 to generate the component and simplifies the process of including code from GitHub repositories or gists. Users can specify a GitHub URL and line ranges, and the component renders the code in a clean, readable format. The project is open-source and available for experimentation, with the source code and prompt used to build it shared publicly. This tool could streamline documentation, tutorials, and blog posts by eliminating the need for manual code copying and pasting.

The component is designed to be lightweight and easy to integrate, making it accessible even for developers without deep frontend expertise. It leverages modern web standards like custom elements and shadow DOM to ensure compatibility and maintainability. While still experimental, the tool demonstrates how AI can accelerate the creation of practical developer tools.
