Lustre (hi, author here) has isomorphic components so you can render components both on the client or as realtime LiveView-esque things on the server, which I think is what the commenter was alluding to.

Definitely not a full-stack framework though: firmly a frontend thing just it blurs what "frontend" means a little! Hologram has a wider scope here being built on top of Phoenix.
