That is why this article shares one of the leading mobile backend services and their significant features. You will also explore the traits and benefits of using Mobile Backend as a Service (MBaaS) providers. 

What is a Mobile Backend as a Service?

MBaaS, or Mobile Backend as a Service, is a cloud computing solution that helps run, build, and manage mobile application backends.

The MBaaS platform hooks up apps’ server sides with compatible databases, storage, and computing instances using SDKs and APIs.

Moreover, cloud code functions, push notifications, authentication, networking, and server management are also its properties.

Correspondingly, if you are looking for mobile backend offerings with a free tier, you must consider Back4app, Backendless, 8Base, Firebase, and Kuzzle. 

What are the Features of a Mobile Backend as a Service?

Let’s delve into the pivotal features of mobile BaaS solutions:

Data Model

MBaaS providers support the data modeling process. This approach lets businesses visually display distinct kinds of data, their relations, and traits.

Data models are designed according to your project’s requirements. This feature is also helpful for collecting effective information. 

Improved database performance, more consistency, easy data mapping and fewer dev errors are further advantages of data models.


Another incredible property of backend platforms is the presence of pre-installed APIs. These APIs allow developers to communicate with databases and further server-side functionalities on the fly. 

By the same token, APIs play the role of bridges when it comes to interacting with outer ecosystems and third-party services. Two prominent APIs that the majority of BaaS vendors offer are REST and GraphQL.

Serverless Functions

This single-purpose feature is conventionally employed to accrue business logic to applications without taking care of servers.

However, serverless functions are valuable for automating workflows, shipping required computing instances, and robust code deployments.   


Push notifications and in-app messages are essential to keeping your mobile app users intact. MBaaS vendors have a feature called notifications.

This function permits you to send customized notifications and in-app messages without scripting additional codes. 

What are the Advantages of using a Mobile Backend as a Service?

Here are the leading benefits of building apps with MBaaS:

Fast Time to Market

It is ultrafast in building and running mobile backends using MBaaS solutions. Unlike traditional programming, you can decrease your server-side coding duration by up to 80% with BaaS providers.

Similarly, automated workflows, readymade APIs and visual data models also speed up your time to market. 

No Infrastructure Hassles

When they use providers, dev teams don’t have to administer and upgrade the infrastructure. Yes, MBaaS platforms are responsible for providing fully managed hardware and software resources to businesses and developers.

Focus on User Experience

Mobile BaaS vendors take care of all tasks that occur on the backend. It signifies that the dev teams and businesses can emphasize core competencies and frontend operations. Consequently, it becomes straightforward for companies to confer improved user experience (UX) to app users.
