The Best Backend For Flutter

The Best Backend For Flutter
Flutter App Backend

Are you looking for the best backend for Flutter for your upcoming project? Or are you looking for a BaaS solution to stay concentrated on the frontend functionalities of your Flutter SDK? If yes, read this blog post without skipping a single portion. 

SDKs are significant in programming because they let developers craft highly functional and complicated applications efficiently.

Indeed, software development kits or SDKs are collections of libraries, building blocks, sample code, and debuggers that are imperative to building top-grade websites and applications. 

In this regard, Flutter is the finest multi-platform UI SDK that Google launched in 2017. With 160k repository stars on GitHub, this open-source library is utilized to build applications through a single codebase.

Its cross-platform nature enables dev teams to develop applications for various platforms, including Android, web, iOS, macOS, Windows, Linux, and Fuchsia. 

Moreover, businesses and programmers prefer Flutter because of its fast integrations and short development cycle. According to a recent survey by Stack Overflow, Flutter has been ranked among the ten most used frameworks or libraries with 9.12% votes.

Correspondingly, BuiltWith data shows around 80k+ websites on the internet use Flutter, and 22k are only from the United States.

These figures present massive use of this SDK, but you can improve the productivity of your Flutter project with the proper backend. 

So, this article will discuss the best backends for Flutter with their core credentials and pricing details. Furthermore, we will also talk about why you need a backend for Flutter.

Why Use Backend as a Service for a Flutter app Backend?

The communication of the Flutter application with server-side functionalities refers to the Flutter backend.

It typically comprises a database, server, and application. Using Backend as a Service (BaaS) could be the best option to fulfill backend requirements for Flutter apps.

BaaS, or Backend as a Service, is a cloud computing model that lets the developers employ all server-side features.

This way, Flutter developers can only emphasize client-side code and core competencies. Yes, BaaS solutions take care of all backend tasks.

The major BaaS offerings are real-time database management, authentication, cloud functions, storage, remote configuration, hosting, etc.

You can sync applications with cloud backends using SDKs and APIs. Yes, BaaS platforms come with built-in API and SDK support for smooth backend development.

In addition, you don’t need to pay for hardware resources to perform server-side operations with these cloud services.

BaaS Benefits

Let’s discuss the key BaaS benefits to understand its significance for Flutter’s backend:

Accelerate Development

Fast development is an evident benefit of using Backend as a Service (BaaS) solutions. Server-side development is a time-consuming task.

But with pre-built authentication, DB management, and managed servers, crafting, deploying, and hosting applications becomes swift. 

So, reusable scripts and a ready-made backend can save 80% of the development time you invest in server-side coding. Less time to market and more focus on core business are also advantages of BaaS.


Extending and reducing instances is seamless because of the scalable nature of BaaS vendors. These platforms permit developers to add servers, CPUs, and further resources within clicks.

In this regard, most CSPs follow a pay-as-you-go pricing model. That means you only have to pay for used resources.

Ease of use

BaaS is easier to use than other cloud computing models, such as PaaS or IaaS. You can find all necessary functionalities on a single dashboard and quickly generate the backend.

Mainly, it is highly flexible to integrate needed features through APIs and SDKs.

Which Backend is Best For Flutter?

Here are the top 8 backends for Flutter:

1. Back4app
