About

Novu routes notifications across in-app, email, SMS, push and chat through one trigger API and a drop-in Inbox component. The MIT-licensed core can be self-hosted, but features such as SSO, RBAC and email tracking stay in Novu Cloud, which runs in the US, EU and five more regions.

What you can do with it

Trigger multi-channel notification workflows with digests and delays
Embed a real-time notification inbox in React, Vue or Angular apps
Connect an AI agent to Slack, Teams, WhatsApp and email conversations
