This is way oversimplified. You can build a completely static website with NextJS. What I love about it is that you can do everything : SSR by default, SSG as an option, and awesome features like ISR etc.

However, the way NextJS implements SSR is really weird right now : if you use their <Link/> component, the pages props are actually fetched with an XHR request, then the page is rendered. I don't know why. It does feel like an SPA in the end.
