A Chat API is the backend engine that powers real-time messaging inside your app. It handles everything from sending a "hi" to delivering rich media, managing group conversations, and syncing messages across devices. But here's the catch: a Chat API is only as good as its ability to deliver every message, on any network, anywhere. And that's where most solutions fall short. To understand why, you need to look at the three transport protocols that power the internet—and their trade-offs. TL;DR: TCP is reliable but slow on poor networks due to head-of-line blocking. UDP is fast but lossy—unsafe for chat alone. QUIC combines speed + security but faces firewall compatibility issues. Nexconn's hybrid protocol dynamically switches between TCP and QUIC, delivering 30% lower connection latency and 40% better performance in infrastructure-limited regions. Back in the day, TCP served as the foundational pillar of the modern internet. It was created way back in 1981, and it makes sure your data arrives safely.…
