Website Block Builder (block-build-pro.base44.app) is outside the top 1 million sites. It is built with Vite, React and Tailwind CSS; it carries traces of Base44, an AI site builder.

The page shows little text before its JavaScript runs, so we also read its own scripts (/assets/index-TTVS9KUA.js, /static/js/badge.js) for traces.
