Talk Let is a self-hosted, web-based communication platform designed specifically for academic institutions.
It enables secure, structured, and real-time communication between students and professors, overcoming the limitations of generic messaging apps like WhatsApp or Telegram.
The system is built with Golang on the backend, HTMX + Alpine.js on the frontend, and uses PostgreSQL for database management.
