Build me a browser based coding workspace where someone can pick a starter project, open it in an editor, change files, run it in an in browser terminal, and see a live preview without installing anything locally.

I want it to feel like a lightweight online IDE, with a file explorer, multiple files open at once, theme switching, resizable panels, and an AI helper that can answer questions and help edit code. It should support a good starter library for common frontend, backend, and full stack projects, and let users save their playgrounds after signing in. Add GitHub and Google login, basic profile and favorites, and store project data in MongoDB.

Also include real time collaborative editing so two people can work in the same project together. If you need current docs for the browser runtime or editor libraries, look them up online. Keep the experience polished and simple for someone who just wants to start coding in the browser.
