what is github1s fr?

github1s is a browser trick that lets you instantly open any GitHub repository in a full VS Code editor, the same coding environment professional developers use, right inside your web browser, with no installation required. The trick is almost embarrassingly simple: just type "1s" after "github" in any repository URL. So github.com/microsoft/vscode becomes github1s.com/microsoft/vscode, and the page loads with a VS Code-style interface where you can browse files, read code, search across the project, and navigate the folder structure with all the familiar editor conveniences. This solves the problem of GitHub's default code viewer being fairly basic, it shows one file at a time, without a file tree on the side or the ability to search across all files at once. github1s gives you that richer view immediately. You would use this when someone shares a repository link and you want to explore the codebase more comfortably than GitHub's built-in viewer allows, or when you want to read through a project's structure before deciding to clone it locally. It also works with GitLab repositories via gitlab1s.com. For private repositories, you can add a personal access token stored only in your browser. The project is built with TypeScript and runs entirely in the browser.
