The next-gen SPA frameworks/libs like SolidJS or Svelte are already very fast and more importantly very small in bundle size. At least much faster and smaller than React or Angular. Therefore the advantages of SSR frameworks like this new one are much smaller when compared to e.g. SolidJS. The performance claims made for this new framework need to be proven by benchmarks. Check out this SolidJS Hackernews clone (Client Side Rendered) https://hackernews-csr.ryansolid.workers.dev https://hackernews-csr.ryansolid.workers.dev (by the way, there're other implementations like Remix or Svelte as well) IMO very hard to beat. For larger apps we can use component based code splitting. The new SSR frameworks are very complex. So there's a downside to it. Of course there's a big market for the cloud providers as you need to run and pay for a server for your SSR instead of simply serving static JS! That's why there's such a hype lately. I'm not convinced that the performance gains are worth the complexity, costs or vendor lock in. Again, check out the SolidJS example app I've linked above and measure for yourself if you really need the additional cost and complexity of a server pre-rendering, hydrating, etc..
