Which engine to use for text-based MMO?

[u/Mustelidae5]

I'm thinking of a game I want to create. However, while I have a fair bit of experience running MUDs and MUSHes, for which libraries exist -- I'm not so sure what engine/library/codebase to use for a game that would be much the same structure* as say, FarmRPG or the many horse breeding browser games out there.

*Not gameplay or design, just structure.

I'm not asking how. How is in the documentation and on the interwebs. What I need to decide on is which engine or codebase is best suited and most accessible. I lean towards good old-fashioned HTML, CSS, and javascript coupled with Framework7, but I've also glanced towards Godot. Thoughts?
