Novu
Novu is an open-source notification infrastructure designed to simplify the way developers build and manage notifications across multiple channels. It provides a unified API for sending email, SMS, push, chat, and in-app messages, abstracting away the complexity of integrating with different providers. With features like a visual workflow builder, template management, and user preference settings, Novu enables teams to create sophisticated notification flows without writing extensive code. Built with a modular architecture, Novu supports a wide range of providers through a single interface, allowing users to switch or combine services like SendGrid, Twilio, Firebase, and Slack seamlessly. The platform also includes a headless API, SDKs for popular languages, and a self-hosted option, making it suitable for both startups and enterprises that require data privacy and control. Its event-driven design ensures that notifications are triggered in real-time based on user actions or system events. Recently, Novu has expanded its vision to become the communication infrastructure for agents and products, addressing the growing need for AI agents to communicate with users across various touchpoints. This includes features for agent-to-human communication, multi-step messaging sequences, and integration with AI orchestration tools. The project has a vibrant open-source community and is actively maintained on GitHub, with regular updates and a clear roadmap.

Problem solved
Novu solves the problem of fragmented notification systems by providing a centralized, provider-agnostic platform. Developers no longer need to write custom integration code for each messaging channel; instead, they define notification workflows once and let Novu handle delivery, user preferences, and channel fallbacks. This reduces development time, minimizes errors, and ensures a consistent user experience across all communication channels.
