The article kindly phrases the alternative as “use a framework” and links to a page that has only one actual framework: NextJS.

I don’t support React pushing a wholesale shift to NextJS as a starting point for every project, given it’s mostly directed by a single private company (Vercel) that have positioned themselves as the default deployment platform for NextJS apps, publish the documentation, and do not shy away from claiming it as their own.

It has become extremely difficult to distinguish between NextJS features that are community-driven vs profit-driven e.g. api route functions (putting your backend in your React project, so now you will pay them for compute) and NextJS image optimization (famously expensive, and NextJS literally throws warnings if you don’t use it).
