codesandbox/codesandbox-client ? reverse-engineered prompt

I want to build a web application that's an online IDE for rapid web development, very similar to CodeSandbox. The main idea is that anyone can visit the site and instantly start a new project in their browser with zero local setup. The interface should feel familiar, with a file explorer on the left, a main code editor in the center, and a live preview window on the right that automatically updates as the user types.

It's crucial that it has built-in support for popular frontend frameworks like React, Vue, Svelte, and Angular, letting users start new projects from pre-made templates. It also needs a feature to import a project directly from a GitHub repository. The whole point is to make it incredibly easy for developers to prototype, experiment with code, and share their creations with just a link.
