Websockets provide real-time, continuous two-way communication between an app and server, ideal for instant interactions, but resource-intensive.
Webhooks wait until specific events occur before sending notifications, efficient and lighter on resources, but may have slight delays.
Websockets are suitable for apps requiring constant interaction like gaming or messaging, while Webhooks are great for simpler, less frequent updates such as notifications or emails.
Choosing between Websockets and Webhooks depends on user behavior, preferences, and infrastructure management, tailored to specific project needs.
