Novu is an open-source communication infrastructure that enables products and agents to reach users across multiple channels through a single API and unified conversation model.

The tool addresses the problem of managing multi-channel communications without rebuilding integrations repeatedly. Rather than forcing developers to construct inbox feeds, provider integrations, and channel webhooks from scratch, Novu provides a unified layer that connects products and agents to channels including Inbox, Email, SMS, Push, Chat, Slack, Microsoft Teams, Telegram, and others. The approach centers on shifting from one-way broadcast notifications to meaningful two-way conversations where users can engage, ask questions, and continue discussions in context.

Novu suits teams building products or agents that need to communicate with users across multiple channels without managing separate integrations for each one. The tool is particularly valuable for applications where users expect threaded, conversational communication rather than static notifications. It provides both a backend API and React-based UI components for building notification interfaces.

The project maintains a substantial base of real-world adopters, as evidenced by the fact that almost all open issues are raised by outside users rather than the core team. Maintainers typically respond to new issues and pull requests within a few days. Work in the issue tracker is dominated by bug fixes and contributions tied to community initiatives.
