WebSockets Development

Persistent connections for live dashboards, chat and collaboration.

Discuss your project
Polling an endpoint every few seconds works until it does not: it is wasteful at scale, always slightly stale, and gets worse exactly as more people use it. WebSockets replace that with a connection that stays open and pushes when there is something to push. The engineering is in the unglamorous parts — reconnection when a phone changes network, replaying what was missed while disconnected, and scaling connections across more than one server without losing messages.

Why we use it

We use WebSockets where liveness is the product: an operations dashboard several people watch at once, a chat or support interface, a booking screen where two users must not claim the same seat, or a long process reporting real progress. We do not use them for data that changes hourly. A persistent connection per user is an operational commitment, and where a page refresh or a periodic fetch would do, that is the cheaper and more robust answer.
