Open Source Push Notification Software

Push Notification software manages the delivery of real-time alerts and messages across mobile devices, desktops, and web browsers. These tools provide a unified API to route notifications through multiple channels such as SMS, email, and web push. This type of software is for developers and system administrators who need to trigger instant alerts based on specific system events. Self-hosting these apps ensures that sensitive message payloads and user device tokens remain on private infrastructure instead of passing through external notification gateways.

This page lists 5 open source tools in the Push Notification category. The most popular are Novu, Ntfy and Gotify. Most use the MIT or AGPL-3.0 license, and 5 offer an official Docker image.
