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.

I'm not in the JS space, but if my twitter feed is anything to go by it'll be https://remix.run/

Still next.js, probably. Keep an eye on Svelte.

I think sveltekit will gain a lot of momentum
