ParallelCode: Collaborative Code Editor
ParallelCode is a real-time collaborative code editor that lets multiple users write and edit code simultaneously in shared documents. It features live synchronization powered by WebSocket/STOMP and Redis Pub/Sub, ensuring all participants see changes instantly. The backend is built with Spring Boot and PostgreSQL for auth and document management, while the frontend uses React/Vite for a fast, responsive editing experience. It's containerized with Docker and secured with JWT-based authentication.
