SPEED
You can't even catch up with it.
Written on top of C, ported to Node.js.
Built with one of the fastest available technologies.
average time to distribute a message to 1k users with just 200m CPU/200 MB RAM
~200k
virtual limit of connections on each allocated 1 CPU + 1 GB pair
COMPATIBILITY
Pusher compatible. Plug-and-play.
You don't need to replace your existing code.
You just change the connection details.
let client = new PusherJS('app-key', {
wsHost: '127.0.0.1',
wsPort: 6001,
forceTLS: false,
encrypted: true,
disableStats: true,
enabledTransports: ['ws', 'wss'],
});
let channel = client.subscribe('chat-room');
channel.bind('message', (message) => {
//
});
PRODUCTION-READY
You can deploy it in production.
You can scale to hundreds of servers with the Redis or NATS adapter and you won't lose performance.
Resilient enough so you can have a good night sleep.
AT SCALE, WITH CLOUDFLARE
Ever dreamed about Serverless WebSockets?
Soketi can be deployed to Cloudflare Workers. All around the world, closer to your users. Same Pusher protocol.
APP MANAGEMENT
Built-in app management
Just like Pusher, you can define your own app credentials and have full control over the access.
You don't even need Pusher for it - and you can read from the most popular databases, like MySQL or DynamoDB.
EXTRA
HTTP Webhooks
Trigger HTTP requests whenever a channel gets occupied.
Pair it with Lambda functions and soketi will invoke them for you.
import { createHmac } from 'crypto';
exports.handler = async ({ payload, headers }) => {
let hmac = createHmac('sha256', process.env.SOKETI_SECRET)
.update(JSON.stringify(payload))
.digest('hex');
let receivedSignature = headers['X-Pusher-Signature'] || null;
if (receivedSignature !== hmac) {
return;
}
payload.events.forEach(({ name, channel }) => {
if (name === 'channel_occupied') {
console.log(channel + ' is now occupied.');
}
});
};
TESTIMONIALS
People are already convinced.
Soketi is awesome! I replaced Pusher and it only took 5 minutes to deploy. It’s a great alternative for the expensive alternatives out there if you have the experience to manage your own infrastructure.
Soketi makes it a breeze to setup what is basically a on-premise Pusher server, including webhooks and multiple app support. Blazing fast and configurable to scale. 💪
We're big fans of Soketi 😁. We've got it scaling up to 200k connections at the moment which is brilliant.
Convinced? Real-time as it should be.
You can install it via NPM, Docker or Kubernetes, either it's cloud or on premises. The only limitation is your infrastructure.
