Firebase has emerged as one of the most commonly employed Backend as a Service (BaaS) platforms in Flutter applications. This is due to its capacity to streamline development, encompassing nearly all the requisite functionalities for your application, and its user-friendly nature.

Before we proceed, let's establish a definition for Backend as a Service (BaaS).

Understanding Backend as a Service (BaaS)
Backend as a Service (BaaS), also known as "mobile backend as a service" (MBaaS), is a cloud computing service model that provides developers with pre-built backend infrastructure to support the front-end development of applications. BaaS platforms offer a range of services and functionalities, such as databases, authentication, storage, serverless computing, and more. By utilizing BaaS, developers can streamline the development process, as they don't need to build and manage backend components from scratch. This allows them to focus more on creating engaging user experiences and frontend features while relying on the ready-made backend services provided by the BaaS provider.

Now that we've established what Backend as a Service (BaaS) means, let's explore the other Firebase alternatives with the pros, cons and peaks and pricing.
