Headless Browser

A headless browser is a web browser that operates without a graphical user interface (GUI). It runs on a server and can be controlled programmatically. Speed Kit uses headless Chrome to render Client-Side Rendered (CSR) pages on the server. It visits the page, executes the JavaScript to build the content, and then takes a snapshot of the final, fully-rendered HTML. This snapshot can then be cached and served instantly to users, solving the inherent performance problems of CSR.
