Novu Has a Free Notification Infrastructure That Handles Every Channel

#novu #notifications #api #opensource

Building notifications means integrating email, push, SMS, in-app, and chat — each with different APIs and delivery logic. Novu unifies all channels into one API with a visual workflow editor.

What Novu Gives You for Free

  • 30,000 events/month on free tier
  • Multi-channel — email, SMS, push, in-app, chat
  • Workflow editor — visual drag-and-drop notification flows
  • Digest — batch notifications ("You have 5 new messages" instead of 5 emails)
  • Preferences — per-user channel preferences
  • In-app inbox — drop-in notification center component
  • Content management — Handlebars templates
  • Self-hostable — Docker Compose

Quick Start 

npm install @novu/node
Enter fullscreen mode Exit fullscreen mode 
import { Novu } from '@novu/node';

const novu = new Novu(process.env.NOVU_API_KEY!);

await novu.trigger('welcome-workflow', {
  to: {
    subscriberId: 'user_123',
    email: 'user@example.com',
    phone: '+1234567890'
  },
  payload: {
    name: 'Alice',
    loginUrl: 'https://app.com/login'
  }
});
Enter fullscreen mode Exit fullscreen mode

One trigger sends email + push + in-app based on your workflow.

Workflow (Visual Editor) 

Trigger → Delay (5 min) → Email
                       → In-App notification
                       → If not opened after 24h → Push notification
                       → If still not opened → SMS
Enter fullscreen mode Exit fullscreen mode

In-App Notification Center 

import { NovuProvider, PopoverNotificationCenter, NotificationBell } from '@novu/notification-center';

function App() {
  return (
    <NovuProvider subscriberId="user_123" applicationIdentifier="YOUR_APP_ID">
      <PopoverNotificationCenter>
        {({ unseenCount }) => <NotificationBell unseenCount={unseenCount} />}
      </PopoverNotificationCenter>
    </NovuProvider>
  );
}
Enter fullscreen mode Exit fullscreen mode

Drop-in notification bell with real-time updates.

Digest (Batch Notifications) 

// Instead of 10 separate emails for 10 comments:
// Novu sends ONE email: "You have 10 new comments"

await novu.trigger('comment-notification', {
  to: { subscriberId: 'user_123' },
  payload: { commentAuthor: 'Bob', postTitle: 'My Post' }
});
// Novu automatically batches based on your digest settings
Enter fullscreen mode Exit fullscreen mode

User Preferences 

// Users can control their notification preferences:
await novu.subscribers.updatePreference('user_123', 'marketing-workflow', {
  channel: { email: false, inApp: true } // No marketing emails, only in-app
});
Enter fullscreen mode Exit fullscreen mode
