Next just bought its biggest upcoming competitor—SvelteKit. Next is the best that React has to offer but it still has flaws. Svelte and SvelteKit are so awesome you cannot believe it before you've built something bigger and so much ahead of the entire React ecosystem. We migrated a huge/complex React app in a month and the difference is night and day (performance/bundle size/dev productivity). React was great but it's time to move on.
I'm disappointed by Rich. Instead of thinking bigger, raising money (it would have been so easy, Rich, instead of doing proud conference talk after talk why didn't you talk to a VC??)—he just cashed out (sky-high compensation and ESOP). Not a rant and to give you some background, one major reason we went with SvelteKit was not to rely on the Next team. And now, I am again with them...
Now we have a monopoly of rare, modern SSR frameworks.
