Remix is probably the most notable, but there’s Astro as well: https://astro.build/

My impression on Remix is fairly solid, but it doesn’t have quite the “just write and deploy” appeal that Vercel’s done quite a good job with, and they’re somewhat trailing behind Next.js in terms of tracking newer React features (which, in practical terms, doesn’t matter much, since even beta Next.js features tend to ship in a very alpha state of quality).

That said, if you’re willing to sweat a bit on getting something deployed, Remix delivers a pretty good experience overall.

I've switched to running new projects on Remix after using Next.js for many years. Remix is just much more sane. Next.js feels like they are aiming to statically precompile everything and do some automagic with the rest all the while locking useful features under Vercel.

I just want to write my SSR applications with dynamic data and deploy them to Docker, Next is making it harder than it needs to be.
