Why Next.js instead of WordPress
A Next.js site produces finished HTML before anyone visits, so the browser never waits on a database or a dozen plugins. WordPress rebuilds the page on every request, and the more add-ons it carries the slower it gets. The gap is often several times over, and Google has counted load time toward ranking for years. It also removes a whole category of problems: plugin updates that break the layout, and security holes in add-ons nobody maintains.
