Fresh is out, neat! But are there other "hybrid" frameworks out there?

Fresh just came out, and it really reminds me of Phoenix which also handles backend development and also hydrates frontend with reactive components.

Of course, there is SSR in React/Vue/Svelte, and we can also think of Meteor.js but it seems to me that this is not the same intention behind it as those "hybrid" frameworks.

Anyway, do you know any other framework that does server side rendering and handles hydration/reactivity too?

You can cite any framework in any language of course!
