Confused between WebRTC and WebSockets for your real-time app? ...

1. What is WebRTC and When can it be Used?

WebRTC (Web Real-Time Communication)...

You should use WebRTC when:

You’re building a video or audio calling application.
You want secure, encrypted peer-to-peer file transfers.
Your app needs screen sharing or real-time collaboration (like whiteboarding).
You require adaptive media quality based on network conditions.

WebRTC reduces server load...

Key Features:
- Peer-to-peer connections (less server load)
- Adaptive video/audio quality
- Built-in encryption (DTLS + SRTP)
- NAT traversal (STUN/TURN)
- Best for video calls, telehealth, and real-time collaboration
