Novu

Novu is an open-core notification infrastructure platform built for developers who need to deliver multi-channel notifications without building the plumbing from scratch. The core technology is MIT-licensed and publicly available on GitHub, where the project has accumulated over 39,000 stars and more than 400 contributors. It combines a drop-in <Inbox /> React component with a unified API that routes notifications across email, SMS, push, chat, and in-app channels.

What It Is

Novu sits in the "notification infrastructure" category — a layer between your application logic and the various delivery providers (Twilio, Sendgrid, Resend, Slack, FCM, etc.) that actually move messages. Instead of writing separate integrations for each provider and channel, developers define workflows once through Novu's API or dashboard, then trigger them with a single call. The embeddable <Inbox /> component handles the in-app notification feed, real-time delivery, user preferences, and snooze functionality out of the box.

Open-Core Architecture

Novu describes itself as a "commercial open source company" using an Open Core model. The core platform is MIT-licensed; enterprise features under the /enterprise folder and certain dashboard modules are covered by a commercial license. This means teams can self-host the open-source version, while enterprise customers can access SSO, RBAC, HIPAA BAA, and advanced data residency options through the commercial tier.

Channel and Provider Coverage

The platform supports five notification channels, each with multiple provider integrations:

• Email: Sendgrid, Mailgun, SES, Postmark, Resend, Mailjet, Brevo, SparkPost, Outlook 365, and more
• SMS: Twilio, Plivo, SNS, Vonage, Telnyx, Infobip, Clickatell, and others
• Push: FCM, APNS, Expo, OneSignal, Pushpad
• Chat: Slack, Discord, MS Teams, Mattermost
• In-App: Novu's own embeddable Inbox component

Developer Workflow and Tooling

Novu is designed to let teams start with a UI-based no-code workflow editor and graduate to code-first workflows when runtime control is needed. The @novu/framework package lets developers define workflows in TypeScript alongside their application code, with support for React Email rendering, Zod payload schemas, and local data access. A Digest Engine batches multiple events into a single notification (e.g., a weekly email digest). The block-based email editor is powered by React Email. Novu also ships a Copilot feature and an MCP server (announced as "Novu MCP is live") for connecting AI agents to the notification platform.

Update: Novu MCP and Recent Releases

The homepage banner highlights that Novu MCP — an MCP server for connecting AI agents — launched recently. The GitHub repository shows active development with the latest release being @novu/react-native@v3.16.0 published in April 2026, and the repository was last pushed to in May 2026. The project roadmap and changelog are publicly available, signaling ongoing product investment across both the cloud and open-source tracks.

Why It Got Attention

Novu won a Product Hunt Golden Kitty Award in 2023 and reached the #1 spot on Hacker News. The GitHub repository's 39,000+ stars and 400+ contributors reflect substantial community traction for an infrastructure-layer tool. The project's framing — "notification logic shouldn't live inside the database" — resonated with developers who had previously hand-rolled notification systems across multiple providers.
