Novu
Open-source notification infrastructure.
Novu is the leading open-source notification platform. Self-host or use the cloud. Workflow editor, multi-channel routing, in-app feed component, BYO providers.
Growth work lives or dies on targeting and measurement. What matters is whether behavioral triggers can be built without engineering time, whether the event stream supports attribution past the open, and whether deliverability holds when broadcast volume shares a reputation with product email.
Against behavior-triggered journeys, broadcasts, and winback campaigns measured on revenue, Novu covers scheduling, event stream, the suppressions API, and multi-tenant support, and does not cover operating track record. Whether that gap matters depends on how central those are to the build.
