Novu: Open-source notification and agent communication infrastructure for products and AI agents.
Novu is open-source notification and agent communication infrastructure that connects AI agents and products to customers across multiple channels using a single API. It provides prebuilt in-app inbox components, real-time notifications, user-controlled preferences, digests, and rate limits. The platform handles routing, conditions, delays, and fallbacks across channels like email, SMS, push, WhatsApp, Slack, Microsoft Teams, and Telegram. It also enables two-way AI communication and human-in-the-loop approval before agents execute tasks. Novu is built for engineering teams seeking to centralize communication workflows while maintaining full control over data through managed cloud or self-hosted deployment options.
