Open Source Backend as a Service Providers

Are you looking for a BaaS open source solution? Here is an in-depth analysis of ten excellent open source backend providers, including the core features and pricing model.

Cloud computing has shaken up every industry since its invention. Indeed, the majority of the businesses prefer to pick any cloud computing model to successfully release, build and run their web or mobile applications. Hereof, Backend as a Service (BaaS) is an outstanding choice that startups, SMEs and big enterprises like to use.

However, open-source property adds more value to the services of BaaS platforms, but it is still complicated to find credible BaaS open-source providers. So, this article shares one of the top open-source BaaS platforms with their core features and pricing models.

Overview about Backend as a Service

Backend as a Service (BaaS) is a cloud computing model that permits the developers to connect the server-side of applications with cloud storage and other functions through SDKs and APIs.

With the robust support of BaaS, it becomes very convenient for businesses to emphasize frontend and core operations because backend vendors take care of server-side tasks.

The BaaS industry is expanding rapidly among businesses. According to a recent forecast by Verified Market Research, the BaaS market value will be around 1,637.94 billion USD by 2030.

This value was only 16.43 billion USD in 2021. It means Backend as a Service has the potential to grow with 84% of the compound annual growth rate (CAGR) from 2022 to 2030.

Similarly, another research report of MarketsAndMarkets claims that the market worth of the Cloud MBaaS industry will reach around 5.9 billion USD by 2025.

This research report only covers the use of MBaaS for Android and iOS applications with core backend services database management, authentication, storage and backups etc.

On the contrary, if we talk about open-source BaaS platforms, then Back4App, Parse, AWS Amplify and Kuzzle are prominent ones.

BaaS Core Features

Here are the core BaaS features:

Realtime Databases

The major feature that attracts developers and companies toward open-source BaaS platforms is the availability of real-time databases.

These databases don’t only update and query information spontaneously but also have the ability to store and sync data when a user goes offline.

User Authentication

It is complicated to authenticate a user and safely keep his data in the cloud. But BaaS vendors made it very smooth for developers to verify users’ identities without risking security.

In this regard, Backend as a Service platforms enable user authentication through email, passwords, phone numbers and a variety of social media applications.


Notifications have great importance in engaging and retaining application users nowadays. Open-source BaaS providers are giving outstanding services in this regard.

Whether you are looking for in-app messaging, email or push notifications, you can get everything with your BaaS vendor. You just need to enable the notification’s function.


BaaS open-source providers allow the developers to integrate their applications and backends with various APIs and social networking apps.

By the same token, coders can also connect their apps with SDKs and even third-party libraries to improve the app’s performance.

Cloud-Based Storage

Limitless cloud-based backend storage is another appealing feature of BaaS platforms. Although the free plans of these backend services confer limited storage, but their pay-as-you-go pricing property allows them to scale storage resources anytime.

For a complete list of BaaS features, read the article The best BaaS features to grow your app.

Advantages of a BaaS

Scalable & Secure — It is very flexible to use backend platforms. You can quickly enhance or reduce resources according to the demand of your project. Indeed, Backend as a Service platforms allow extending sources horizontally and vertically. By the same token, 2-factor authentication, customized team permissions and several safety features make it a very safe choice.

Cost-Efficient — BaaS development is inexpensive compared to custom app development. According to Glassdoor, a backend developer charges $83k to $185 yearly in the United States. Withal, the charges of most BaaS vendors start from $25. Even the majority of them offer free-tiers.

Reduces Time to Market — Building server-side of applications is very quick with open-source BaaS vendors. It overcomes the development duration of MVPs. So, startups and businesses can reduce their time to market.

Stops Futile Stack Development — Developers don’t need to build customized stacks and everything from scratch when using the BaaS platform. It prevents unnecessary development, and most of the functions are done only by connecting APIs.

For a full list of the benefits of a BaaS solution, read the article Benefits of using a backend platform.

Advantages of Open-Source

Here are significant advantages of open-source:

  • The top advantage of open-source BaaS platforms is community support. You can’t only access thousands of libraries that are available on the internet, but community forums are also there. Novice developers can ask their queries on these forums from seasoned programmers.
  • Similarly, open-source codes are more reliable and secure because the community can quickly identify errors and security lapses.
  • You can also smoothly migrate from open-source platforms because they don’t come with vendor lock-in features.
  • Less time to market, cost-efficient and merit-based codes are some advantages of open-source for businesses.
