WebRTC vs WebSockets

Developers should learn WebRTC when building applications that require real-time communication, such as video chat apps, online gaming, remote collaboration tools, or IoT device control meets developers should learn and use websockets when building applications that require real-time features, such as live chat, online gaming, financial trading platforms, collaborative editing tools, or live sports updates, as it reduces latency and server load compared to polling techniques like http long-polling. Here's our take.

WebRTC

Nice Pick

Developers should learn WebRTC when building applications that require real-time communication, such as video chat apps, online gaming, remote collaboration tools, or IoT device control

Pros

• It is particularly valuable because it reduces server load and latency by enabling direct peer-to-peer connections, making it ideal for scenarios where performance and privacy are critical, like secure messaging or live broadcasting
• Related to: javascript, html5

Cons

• Specific tradeoffs depend on your use case

WebSockets

Developers should learn and use WebSockets when building applications that require real-time features, such as live chat, online gaming, financial trading platforms, collaborative editing tools, or live sports updates, as it reduces latency and server load compared to polling techniques like HTTP long-polling

Pros

• It is particularly valuable in scenarios where instant data synchronization between clients and servers is critical, such as in IoT device monitoring or interactive dashboards, because it maintains an open connection for continuous data flow
• Related to: http, real-time-communication

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. WebRTC is a platform while WebSockets is a protocol. We picked WebRTC based on overall popularity, but your choice depends on what you're building.

The Bottom Line

WebRTC wins

Based on overall popularity. WebRTC is more widely used, but WebSockets excels in its own space.
