app push notifications
Last updated on
Developers and marketers use notification systems to communicate with and engage app users, but these systems come in various forms. Some opt for commercial notification systems that offer a set of features and capabilities for a fee. Those who want more control over their notification system might opt for open source notification tools.
Open source notification tools offer various features and services that developers can leverage to build a custom notification system for their applications. With access to the source code, developers have more control, and they also benefit from lower costs.
However, setting up all the moving parts of a notification system is cumbersome.

With MagicBell, you can have a complete notification system up and running in less than an hour to notify users wherever they are and how they prefer.
