RealMQ is a free and open source backbone for real-time communication. Our core values are performance and integrability. The platform is built around a convenient REST-API to manage access control, data channels and users/devices. Messages, events and data are exchanged via the battle proven MQTT protocol which is lightweight, fast and well established in the world of IoT. Clients connect to our highly scalable MQTT broker that takes care of delivering messages to all connected subscribers. On top of this slim but flexible core you can build awesome realtime products and services around use-cases like:
- Device to device communication
- Exchange signals / send and receive realtime events
- Broadcast messages or events to segmented users
- Aggregate and dispatch data
- Emit sensor/IoT Device data
- Chat
We follow the API first approach, as we see our API as the central component in our architecture. Our mission is to build a developer friendly API with industry standard patterns and tools like RESTful design principles and an OpenAPI specification. It goes without saying that all requests are TLS encrypted and authentication is backed by security tokens (Bearer authentication).
Message history can be enabled and fine tuned on channel level. Once enabled, all messages published to the channel will be kept for a configured amount of time. Persisted messages can be retrieved via API history resource.

// Create a new channel that keeps messages for 2 weeks
const channel = await realmq.channels.create({
history: '2 weeks'
});
// Retrieve the history (last 20 messages)
const history = await realmq.history.query({
channel,
limit: 20
});curl -X POST -H 'Authorization: Bearer token...' -H 'Content-Type: application/json' \

https://api.realmq.com/client/v1/channelsThe RealMQ platform comes with built in multi-tenancy / project support. You have the ability to operate multiple, isolated data containers. Our so-called Realms make it a breeze to setup clean separation of different applications and launch on-the-fly environments (like prod, test, demo). Realms are completely transparent to clients, as we are able to route all RTM and API calls into the correct Realm via auth tokens. For Realm administration and access management you can operate directly against a dedicated administration api.
We provide SDKs for NodeJS and the Browser. Other major platforms will follow. The SDKs aim for seamless integration and hence provide you with a convenient interface for interacting with our platform and are first class helpers for building reactive realtime apps.
Explore code sample
import RealMQ from '@realmq/node-sdk';
// Initialize with auth token
const realmq = RealMQ('sub_kg2...');
// Publish messages of any format
realmq.rtm.publish('some-channel', {
status: 'Exited!'
});
// Subscribe to real-time updates
realmq.rtm.subscribe('some-channel', msg => {
console.log('Horay! New message received:', msg);
});
// Retrieve subscriptions
const subscriptions = await realmq.subscriptions.list();The RealMQ platform comes with fine grained access control capabilities, that can be managed via API. We don’t enforce a specific content type for the messages that are sent between clients. It’s totally up to you to decide what the payload contains. This allows for easy integration of any kind of end-to-end encryption for messages. On top of our TLS this establishes an additional security layer.

The app can be configured via environment variables, that can also be injected via .env file.
For a complete list of configuration options see config docs.
The RealMQ platform comes with a docker compose setup aimed for local development.
To get you started, simply run:
npm run devThis command will:
- 🏁 setup
.envfile - 📦 fetch and install all dependencies.
- 🔒 generate TLS certificates and setup local dns for
[api.|rtm.]realmq.local - 🤖 launch the mqtt broker on rtm.realmq.local:1883
- 🐳 launch the app on https://api.realmq.local
- 🔥 code reload - restart app upon code changes
npm run dev generates self-signed certificates. In order to trust them on your machine, import the ROOT CA cert from certs/dev-ca-root.crt.pem.
- Firefox: Go to "Preferences > Advanced > Certificates > View Certificates > Authorities > Import" and select the CA certificate.
- Chrome: Go to "Settings > Manage Certificates > Authorities > Import" and select the CA certificate.
