## AI overview

This article introduces RSC Explorer, a browser-based tool for examining how React Server Components serialize and deserialize React trees through the RSC protocol. It demonstrates JSON-like server stream data, client-side JSX reconstruction, and streaming behavior. The tool is a single-page application that runs locally in the browser and uses React's actual RSC protocol packages.
