DisChat – High-Performance Real-Time Chat Platform

DisChat is a high-performance, Discord-like chat platform engineered for scalability and real-time responsiveness. The backend is written in Rust using the Actix-Web framework, delivering sub-millisecond message latency and effortless handling of thousands of concurrent WebSocket connections.

The architecture uses a dual-database strategy: PostgreSQL manages relational data such as users, channels, and permissions, while MongoDB stores chat message history for flexible, high-throughput document storage. This combination ensures both data integrity and write performance at scale.

The frontend is built with TypeScript, delivering a responsive and type-safe user experience. Features include server/channel organization, direct messages, real-time presence indicators, file sharing, and role-based access control — mirroring the core workflow of Discord with a lean, modern stack.
