What the source says
fx0 is an open-source page design agent that turns a written brief into a single HTML file with a live preview and saved design versions. It combines a conversational design interface with an inspectable libfx-based implementation. The output is a standalone HTML design artifact, while the hosted workflow connects model usage to the signed-in Vercel team; it is not evidence of a deployed production website.
