Novu Open-Source Notification Infrastructure Platform
Novu is an open-source notification infrastructure platform that provides a unified API for sending notifications across email, SMS, push, in-app inbox, and chat channels. It includes a workflow engine, digest system, subscriber preferences, and embeddable React notification center.

Novu is an open-source notification infrastructure platform designed for developers who need to manage multi-channel notification delivery at scale. Rather than building separate integrations for email, SMS, push notifications, in-app messages, and chat platforms, Novu provides a single API and workflow engine that orchestrates delivery across all channels simultaneously.
What this skill actually does
What is Novu?
How It Works
Novu operates through a workflow-based model where developers define notification templates that specify content and delivery rules for each channel. When a notification is triggered via the Novu API or SDK, the workflow engine evaluates subscriber preferences, applies digest rules (batching multiple events into a single notification), and routes the message through the appropriate provider for each channel.
The platform supports over 60 notification providers out of the box, including SendGrid, Mailgun, Twilio, Firebase Cloud Messaging, Slack, Discord, and Microsoft Teams. Adding a new provider is a matter of configuration — no code changes required for supported integrations.
Key Features
The embeddable Inbox component is one of Novu’s standout features. It provides a drop-in React component that gives applications a fully functional in-app notification center with real-time updates, read/unread tracking, and subscriber preference management. The Inbox renders notifications with customizable templates and supports actions like marking as read, archiving, and custom click handlers.
The Digest Engine intelligently batches notifications — for example, instead of sending 50 individual “new comment” emails, it combines them into a single digest delivered on a configurable schedule. The workflow engine supports conditional logic, delays, and multi-step sequences.
Architecture and Deployment
Novu is built with TypeScript and Node.js, using MongoDB for persistence and Redis for queuing and caching. The platform can be self-hosted via Docker Compose or deployed on Kubernetes. Novu also offers a managed cloud service for teams that prefer not to operate the infrastructure themselves.
Official SDKs are available for Node.js, Python, Go, Ruby, Java, Kotlin, PHP, and .NET. The REST API is fully documented with OpenAPI specifications, making integration straightforward from any language.
Integration Points for Agents
For AI agent workflows, Novu serves as the notification layer that handles the complexity of multi-channel delivery. An agent can trigger a Novu workflow with a single API call, and Novu handles subscriber preferences, channel routing, content rendering, and delivery tracking. This is particularly useful for alerting systems, user engagement flows, and any automation that needs to reliably reach humans across their preferred channels.
