OneSignal vs. Firebase Cloud Messaging (FCM) vs. Firebase Cloud Messaging (FCM)

Although and Firebase are both free to start using, there are some significant discrepancies between the two platforms that need to be addressed. Beyond simply the significant feature and cost disparities, it’s crucial to remember that has consistently invested in enhancing our platform and is committed to always being the best in its class. In contrast, Google’s long-term commitment to Firebase as a notification platform remains unsure.

Because of Firebase’s shortcomings in terms of capabilities, usability, dependability, support, and cost, we created has always been the obvious choice for developers and marketers looking for a free way to get started or an enterprise-level solution for their growing enterprises.

Firebase Cloud Messaging: What is it?

The first item is a “Cloud Messaging” API, which is used by mobile applications to notify users who have downloaded their Android applications. Before Firebase was acquired, this Android device cloud API was known as “Google Cloud Messaging.” Sending notifications to devices that were downloaded from the Google Play Store is only possible using the FCM API.

The purpose of this criterion is to decrease battery usage on Android devices. Google requires that Android apps released through Google Play use a single, shared connection supplied by FCM rather than allowing all Android applications to create individual background connections for notifications. Following this connection with the FCM API, Google offers an API that allows for the sending of messages to applications. Because of this demand, itself makes use of the FCM API.

Messages are forwarded by Firebase to the Apple Push Notification Service when using the FCM API to send notifications to iOS devices (APNs). The FCM API and APNs are comparable and share the same goals.

The Firebase Messaging Notification Composer is the second item. Developers and marketers can use the Notification Composer to build mobile push notifications using an online dashboard, deliver those messages to a specific audience, and examine simple metrics on those messages.

Firebase also provides a product called “In-App Messages,” which are pop-up messages that may be written via the Firebase dashboard and then displayed to users while they are using the developer’s mobile application. This product is offered separately from Firebase Cloud Messaging.

What is the past, present, and future of Firebase?

A startup named Firebase was purchased by Google in 2014. Google considerably improved the Firebase platform in its early years. Other Google products were moved to become a part of the expanding Firebase product line, including “Google Cloud Messaging,” “Google Analytics for Mobile,” “Admob,” and others. Firebase Cloud Messaging replaced Google Cloud Messaging. Firebase Analytics replaced Google Analytics for Mobile. Even Google’s mobile advertising platform Admob joined Firebase.

A total of 20 products make up the Firebase portfolio, which includes Crash Reporting, App Distribution Capabilities, a Realtime Database, Cloud Hosting, Machine Learning tools, and more.

Around 2019, Google started to halt Firebase’s advancements and scale back several of its current features. A literal iframe around Google Analytics was replaced with Firebase Analytics, which was largely deprecated. The number of new Firebase product upgrades every year decreased from a few dozen to just two or three.

Today, hundreds of thousands of developers still make use of one or more Firebase-branded technologies, such as Firebase Cloud Messaging. However, it looks like Google has delayed investing in Firebase for the time being, therefore Firebase’s future is unknown.


A basic set of functionalities are available in the Firebase Notification Composer for creating notifications and sending them to recipients. A notification’s title, wording, and attachment of a picture can all be customised.

Although Firebase appears to display a preview of the message, users frequently discover that the preview was inaccurate. Many platform features, like as notification action buttons or even iOS notification subtitles, are not natively supported. notification composer, in contrast, displays realistic previews for each type of device. Action buttons, rich media, and subtitles are just a few of the notification features that are natively supported.

Additionally, natively provides full Liquid Templating support, message internationalisation, and user attribute substitution (such as “first name”) inside a message.


Google has not made the maintenance and innovation investments required from contemporary messaging platforms and APIs, despite Firebase once being a viable option for developers seeking a straightforward platform to send notifications. Today, is without a doubt the best option in terms of dependability, usability, functionality, support, and cost.
