Works with your existing stack
const pusher = new Pusher(key, {
cluster: 'cloud',
wsHost: 'ws.sockudo.io',
protocol: 2,
});// config/broadcasting.php
'driver' => 'pusher',
'host' => 'ws.sockudo.io',
'port' => 443,import Sockudo from '@sockudo/client';
const client = new Sockudo({
host: 'ws.sockudo.io',
});What you get
Sockudo Cloud ships the full V2 protocol stack — serial ordering, idempotent publishing, delta compression, tag filtering, and connection recovery — managed for you.
Serial numbers, message IDs, and connection recovery built into every message. Exactly-once delivery without extra infrastructure.
Send only the diff between consecutive messages. Reduce bandwidth by 60–95% for state-heavy channels like live dashboards.
Server-side filter evaluation in ~12–94 ns. Clients receive only the events they care about — no client-side filtering needed.
Clients resume missed messages after a disconnect via a replay buffer. No missed events, no manual re-sync logic.
Drop-in replacement for Pusher Channels. Your existing Pusher SDK code works on day one via Protocol V1 fallback.
Redis, NATS, RabbitMQ, Kafka, or Google Pub/Sub adapters. Scale to millions of concurrent connections across any number of nodes.
Prometheus metrics, structured JSON logs, and health endpoints out of the box. Plug straight into Grafana or Datadog.
HMAC-SHA256 signatures, per-app origin allowlists, rate limiting at both API and WebSocket layers, and encrypted channel support.
Pricing
No seat fees. No per-channel charges. Just messages and connections — predictably priced, ~30% less than the competition.
Kick the tyres. No credit card required.
