🔌Standard Websockets

Stream real-time data directly to your applications with our websocket integration.

What are Websockets?

Websockets allow for two-way communication between a client and a server. Unlike traditional request-response models, Websockets keep a persistent connection open, enabling real-time data exchange. This is perfect for applications that require instant updates like chat apps, online games, trading bots, and marketplaces.
