NextJS is still looking pretty good if you're in React land. There's new competition, like Remix, Astro, etc... but I don't see any of them putting NextJS to bed. I'm starting a new application, and I'm still choosing NextJS.

(Now what you couple with NextJS for data access is an interesting question - this is where there's a lot of innovation. Personally, I'm going with tRPC. I would look at Edge DB, but in this application I'll need a recursive CTE and Edge can't do it.)

Edit: I do think Astro might replace NextJS for purely-static sites, or ones where the "islands of interactivity" pattern is compelling.
