chat-js and NextChat
These are **competitors**: both are full-featured, production-ready chat UI frameworks that serve as standalone frontends for interacting with AI models, and users would typically choose one or the other based on their specific deployment needs (chat-js for customization, NextChat for multi-platform support).
