How Canva Scaled Real-Time Collaboration with WebRTC: From WebSockets to Seamless P2P Communication

Canva enhanced its real-time collaboration capabilities by switching from WebSocket and Redis to a WebRTC-based solution. This transition helped reduce latency, improve scalability, and lower backend load. WebRTC enables peer-to-peer data exchange, leading to more efficient real-time responsiveness. While WebRTC adds complexity due to NAT traversal requirements, it ultimately provides a smoother user experience.
