WebVCall - WebRTC Video Calling Application
A peer-to-peer video calling application built with WebRTC and Quarkus, supporting room-based communication, real-time audio and video, and WebSocket-based signaling.
Project Overview
WebVCall is a modern peer-to-peer video calling application built with WebRTC, designed to provide real-time audio and video communication directly between browsers.
The application uses room-based communication, allowing users to create or join calls with a shared room code without requiring user accounts. It provides a responsive interface with camera and microphone controls, connection status indicators, and support for both dark and light themes.
Technical Challenges
One of the main challenges was establishing reliable peer-to-peer communication between browsers while handling the connectivity issues that can occur across different networks.
WebRTC is used for direct audio and video communication, while the Quarkus backend provides WebSocket-based signaling to help establish connections between participants. STUN and TURN servers are used to support NAT traversal and improve connectivity when direct peer-to-peer communication is not immediately possible.
Another focus was creating a simple calling experience without requiring account creation. Users can enter a display name, create or join a room using a room code, and start a call directly from the browser.
The interface also needed to work across different screen sizes, so the frontend was built with responsive HTML, CSS, JavaScript, and Tailwind CSS.

- Quarkus backend with Java 21
WebVCallA browser-based video calling application focused on real-time peer-to-peer communication with a simple room-based experience.
WebVCall demonstrates how WebRTC can be combined with a Java and Quarkus backend to build a real-time communication application, with WebSockets handling signaling and STUN/TURN infrastructure helping establish connections across different network environments.
