Novu

What is Novu?

Novu is an open-source communication infrastructure platform built for developers and product teams. It provides a unified API and workflow engine to manage multi-channel notifications across in-app Inbox, Email, SMS, Push, Chat, Slack, Microsoft Teams, Telegram, and more. Beyond traditional product notifications, Novu has expanded into agent communication infrastructure, enabling AI agents to reach users through any channel. With embeddable React components, a visual workflow editor, and code-level flexibility, teams can start simple and scale to complex notification logic without rebuilding from scratch.

Key Features

• Embeddable Inbox Component

  Drop a fully functional in-app notification inbox into any React, Next.js, or Remix app with as few as 6 lines of code, complete with real-time delivery, user preferences, and snooze support.

• Multi-Channel Workflow Orchestration

  Build and manage notification workflows across Inbox, Email, SMS, Push, Slack, Microsoft Teams, Telegram, and Chat from a single unified API and visual editor.

• Digest Engine

  Automatically batch and combine multiple events into a single notification — reducing noise for users by delivering grouped summaries via Email or SMS on a configurable schedule.

• Agent Communication Layer

  Connect AI agents (including Claude Managed Agents) to user-facing channels like Slack, Email, and Discord, enabling agent-driven workflows for alerts, approvals, and support.

• Block-Based Email Editor

  Design dynamic, on-brand emails using a visual block editor powered by React Email — no need to hand-code HTML tables.

• Broad SDK & Integration Support

  Server-side SDKs for TypeScript, Python, Go, PHP, .NET, Java, Kotlin, Laravel, and Ruby, plus integrations with Twilio, Resend, Clerk, Stripe, and more.

Use Cases

• In-App Notification Inbox : SaaS products can embed a real-time notification feed directly into their UI, keeping users informed of account activity, comments, requests, and system alerts without leaving the app.
• Transactional Alerts : Send triggered notifications — password resets, payment confirmations, order updates — across Email, SMS, and Push through a single workflow definition.
• AI Agent Outreach : Teams building agentic applications can route agent-generated messages and action requests to users via Slack, Email, or chat platforms without custom channel integrations.
• Digest & Summary Notifications : Platforms with high event volume can consolidate activity into periodic digest emails or SMS summaries, improving signal-to-noise ratio for end users.
• Enterprise Multi-Channel Campaigns : Product and growth teams can design multi-step notification flows across channels with conditional logic, user preference controls, and delivery analytics.
