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.
