What is Novu?
Novu is an open-source notification infrastructure platform that lets developers manage all their product notifications — email, SMS, push, chat and in-app — across channels from a single API and workflow. Building reliable, multi-channel notifications is a deceptively large task: you have to integrate many providers, handle user preferences, manage templates, and orchestrate when and how each message is sent. Novu unifies all of that, so you add rich notifications to your app without stitching together a dozen services yourself.
Its strengths are unification, flexibility and openness. From one place you can define notification workflows, connect your preferred delivery providers, manage templates and respect user preferences across channels, plus drop in a ready-made in-app notification center. Being open source, it is transparent, community-driven and self-hostable, which appeals to teams that want control and to avoid lock-in. The result is consistent, maintainable notifications that would otherwise take significant engineering effort to build and operate reliably.
Novu is a great fit for developers and teams who need to send notifications across multiple channels and want infrastructure that handles workflows, providers, templates and user preferences — without building it from scratch. It sits in the modern developer-infrastructure ecosystem alongside tools for background jobs, API keys and observability. If your product needs professional, multi-channel notifications with an in-app inbox and centralized control, Novu provides an open, flexible foundation that saves substantial engineering time while keeping you in control of your notification stack. Rather than maintaining brittle, custom notification code spread across your application, you get a single, reliable system that scales with your product and adapts as you add new channels and providers over time.
