Real-time made ridiculously simple

Add real-time features to your app in minutes, not months. No Kafka, no WebSocket headaches, no infrastructure ops.

import { init, connect, stream } from "@streamflux/sdk";

init({ url: "wss://api.streamflux.dev/ws" });
await connect();

stream("orders")
  .window(5, "seconds")
  .on("anomaly", (event) => {
    alert(event);
  });
