Detailed Introduction

Kandan Core represents a modern revival of the self-hosted open-source team chat application, Kandan. It is being developed to offer a robust, real-time communication platform specifically designed for teams, leveraging a contemporary technology stack that includes Angular 21 for the frontend, Express/Node/TypeScript for the backend, and Socket.io for real-time messaging.
