What is Firebase? 

Google-backed Firebase is an application development platform that provides the complete set of tools and features required to develop Android, iOS, and Web apps. In addition, it also provides tools for analyzing and visualizing the data, reporting and fixing app crashes, and creating and deploying marketing and product experiments.

Firebase is useful in several situations owing to the advanced integration levels it allows to Google and third-party services. For instance, developers can provide users with a quick way to sign in using Authentication, define audience profiles based on their behavior, and roll out new features progressively after testing.

Firebase core features

  • Powerful analytics tools

At the core of Firebase is Google Analytics and its dashboard is one of the best features of Firebase. It is free to use and can create unlimited reports for up to 500 events each with at least 25 attributes.

You can create custom audiences based on predefined events or user device data and properties, which can be specified with other Firebase features when launching new features.

  • Easier app development

With robust operational functionality, developers can solely focus on developing the app to deliver the best possible user experience. It has several attributes like Cloud Messaging, Authentication, Test Lab, Hosting, Storage, and Dynamic links which seamlessly integrate to make the app development process easier.

  • User engagement tools

Firebase also offers several tools for growth and user engagement and can be linked to third party commercial apps for added functionality. For instance, you can easily link AdWords to segment and define your userbase and improve targeting in your marketing campaigns.

Firebase advantages

  • Firebase A/B Testing

Firebase A/B Testing, with Google Optimize under the hood, allows developers to optimize the application management experience by making it easier to run, analyze, and add scalability according to the user demands. You can make changes to your app’s UI, features, or engagement campaigns to see if you get the expected ROI before rolling them out to consumers.

  • Real-time database

The NoSQL database is based on the JSON document protocol, allowing developers to store and sync the data between clients in real-time. Moreover, the data can be accessed across all devices, and developers do not need backend support to build apps for multiple platforms. 

  • Crash reporting and fixing

Firebase allows end-users to report bugs and crashes quickly and easily. The Firebase SDK logs the crashes automatically and notifies the cause to the developers and testers, who can identify and fix the problems at the earliest.
