What is a real-time web app?

A real-time web app updates instantly for every connected user — chat messages, video calls, live seat maps or notifications — without page refreshes. It relies on persistent connections such as WebSockets and peer-to-peer media through WebRTC.

Who it's for

EdTech, events, marketplaces and operations products where users collaborate, communicate or track activity live.

FAQ

Frequently asked questions

What real-time products have you built?

Highlands Brain, an EdTech platform with real-time chat, WebRTC sessions and geofencing, and Showfest, an event platform supporting large-scale real-time traffic.

WebSockets or WebRTC — which do I need?

WebSockets suit messaging, notifications and live data between server and users. WebRTC is for peer-to-peer audio, video and screen sharing. Many products use both.

Can real-time features be added to an existing app?

Yes. Chat, presence and live notifications can usually be added as new services and components without rewriting the rest of the product.
