Next, Nuxt and Nest are server-side rendering frameworks, based on React, Vue and Angular. There is also Sapper, a new tool based on Svelte.
So far I've tried just Next, and I loved it. And as much as I love Svelte (especially for smaller apps), I'm not sure I want to try Sapper, as it is still in early development and experimental.
What SSR frameworks have you tried and which one did you like best?
