Replyke

Replyke provides the complete user interaction infrastructure layer for modern products, covering discussions, reactions, spaces, feeds, notifications, real-time chat, and follows. It ships pre-modeled data structures so developers avoid weeks of schema design and wiring. SDKs are available for React, React Native, Expo, Node.js, and vanilla JavaScript, all TypeScript-first and open source under MIT. Teams can drop in fully customizable UI components as editable source code, built on shadcn/ui and Tailwind CSS principles.
