Correct me if I'm mistaken, but Hypernova has the javascript rendering siloed as a separate service. Which can be really useful in some cases (especially if you want to render React components from a Rails app).
But if you want it all in one place (reduced complexity and overhead), React Server looks pretty promising.
React-server seems to roll in additional opinions (sane default) about how to go about creating a high performance server-side rendered universal application.
My evaluation is that react-server looks promising for prototyping and first versions of an application where being monolith is a reasonable approach. Hypernova seems like a good fit for organizations that are already building microservices and want to eek some additional performance out of the initial render of their SPAs.
