This article is based on our in-depth domain expertise and provides a list of most popular backend frameworks you may want to select when developing a web or mobile app in 2021-2022. We’ll also provide an overview and comparison of the most used backend frameworks.
As a software business owner, your primary concerns are strategy, finances, business growth, and product marketing, among others. True, you’re not required to have a solid tech background — in most scenarios, a CTO or your outsourcing partner provides that knowledge.
However, it never hurts to be aware of the most popular backend frameworks on the market. On the one hand, it will give you a rough understanding of what skills to look for when assembling a team for the next project. On the other hand, it will show you whether your technology provider’s tech stack suggestions are truly made with your best interests at heart or they simply want to employ available talents from their bench.
So fasten your seatbelts and let us take you for a ride through the most popular web and mobile backend frameworks.
Why are we in the driver’s seat? Glad you asked. Acropolium has hundreds of combined man-years of expertise developing enterprise-grade web and mobile products. We’ve completed projects for a variety of industries using top backend web frameworks — but don’t take our word for it.
So read on to discover why you should go for BaaS (Backend-as-a-Service) and learn the pros and cons of using various backend frameworks.
Backend frameworks: What they are and why use them
Talking about the frontend and backend (or client-side and server-side) tech stack, we refer to the fact that any app functionality heavily relies on the specifics of the components it was built with. These components, usually libraries and frameworks, interact with each other in a multitude of ways, which is why their combination is called a stack.
Well, selecting the most fitting backend development frameworks for your tech stack can make or break the project. Why so?
A framework is a package of pre-written and tested code in a specific coding language, enabling any developer to build upon this foundation. Thanks to this, there’s no need to write popular functions from scratch every time, which immensely speeds up the development.
How to choose the best back end framework
To be crystal clear, you absolutely can develop an app using any language and any framework. However, certain languages and frameworks are better geared toward delivering specific functions:
- Python (with Flask or Django) is the best choice for building big data analytics platforms and training AI models.
- Erlang and Elixir are great for building and managing telecom infrastructures, among other things.
- Node.js, .NET, and Java are the go-to choices for building enterprise-grade software that can continuously run in the background.
- Python and PHP are best for small-to-medium app development (well, they get the job done for large-scale projects too, they’re just usually not the first choice).
But when we talk about selecting a language (and a framework) for your next app, the deciding factor should not be its popularity.
Secondly, you must consider the transparency and ease of reading the code written with that framework. If your developers produce clean code, new teammates will have little trouble onboarding the project. Minding transparency also helps mitigate framework updates, like when Laravel v4.x was replaced with the v5.x, and many compatibility issues arose.
Thirdly, you should select a framework with the best support. We’re not talking about the community size here. All too often, updates to the underlying language force updates to the framework — and your app becomes inoperable till the latest framework version is implemented and the app is updated accordingly. This can be avoided by sticking to the most popular backend frameworks — they are usually the most stable ones.
Benefits of backend frameworks
Now that you have your pointers, let’s briefly cover the benefits of using frameworks for mobile app backend development (this applies to web development too).
Obviously, when developers can create app functionality out of pre-written atomic features, the development process takes much less time. This also results in fewer bugs, which shortens the development cycle and improves the quality of the resulting product.
All framework features are pre-tested and can be scaled quickly and effortlessly. This makes it easier to create an app that addresses demand spikes adequately and scales components up and down as needed.
With frameworks, you can use out-of-the-box code and build upon it. This enables your developers to deliver robust features with clear and streamlined structures without reinventing the wheel.
Most frameworks are open-source, and there’s a huge and passionate community behind each of them, so security issues are addressed adequately. World-known websites and apps like Instagram, Pinterest, Shopify, Coursera, and Reddit are built using Django, Ruby on Rails, Laravel, Node.js, and ASP.NET. You’d better believe these guys take security seriously.
Building a standalone application is not as feasible as enriching an existing one with new functions. Backend development frameworks ensure using RESTful API or GraphQL integrations is much simpler. This way, you can actually make your new app an integral part of a thriving software ecosystem and greatly increase user experience.
Login with Facebook or Google accounts, directly upload your Instagram photos or Pinterest pins, use Google Maps to navigate and leave reviews — these are just the tip of the iceberg when it comes to integrations.
By now, you’ve probably decided the benefits of backend frameworks are too good to pass on, and you’re right. So your next step is selecting the best fits for your future web app from the list of backend frameworks.

5 best backend frameworks for web development
This is Acropolium’s list of the five most popular backend web frameworks around. But don’t think the list is exhaustive: while the entries below can cover nearly the whole range of web development needs, you might need to use some other frameworks, depending on your product specifics. So consider consulting with experts before choosing the tech stack.
Django for Python
Django is one of the most used backend frameworks for Python. It is an open-source Model View Controller (MVC) framework used to build modern, database-driven, highly performant, feature-rich websites and apps. Django uses Python for all operations and ensures great pluggability and code reusability, which allows for reduced coding and shorter development cycles.
Many apps and websites, including the famous ones like The Washington Times, Mozilla, and Discus, run with Django.
Pros of using the Django back end framework:
- Fast to learn, easy to use. Django has a low learning curve and was built with the sole goal to speed up development cycles. It does this job perfectly.
- Robust features. Django handles a vast number of app functions out of the box, significantly reducing the effort needed to create an app from scratch.
- In-depth security. Django comes with built-in protection from SQL injections, cross-scripting, request forgery, and other types of security challenges. It also takes care of user authentication by default, which allows users to store their passwords securely.
- High scalability. Django is the epitome of Python’s concentration on scalability, enabling the websites that run on it to meet their high demand spikes with ease.
- Versatility. Just like Python itself, Django is suitable to develop a wide range of applications, from eLearning platforms to social media and Big Data management tools.
As for the Django disadvantages, there are just a few:
- Django ORM. ORM or Object Relational Mapper provides a set of solutions to various development challenges and… limits you to using the said solutions. If you want or have to do anything in an unconventional way, ORM becomes a crutch instead of a trampoline.
- Monolithic deployment. Once again, due to using ORM, you have to follow certain patterns in all aspects of software development, including deployment. Sometimes you need to add specific functions just to make Django work properly, even if your app actually does not need them.
- In-depth system knowledge is required. Django is an end-to-end development framework, meaning you need to plan every little feature in advance to avoid costly reworks mid-development. Thus, while it is easy to develop apps using Django, you will need additional time to plan everything beforehand.
However, these are more limitations than disadvantages. Overall, Django is a great choice for the rapid and predictable development of various types of apps and websites.
Laravel for PHP
Laravel is an open-source MVC framework for building, deploying, and running PHP applications based on Symfony. It comes with a dedicated dependency manager and modular packages simplifying all operations. Add the ability to easily interact with any relational databases and app deployment tools, and you’ll definitely see why Laravel is the leading PHP framework.
The benefits of using Laravel are:
- Easy authentication. With built-in access management tools, implementing user authentication is simple.
- API-based mail sending. With Laravel, you get API integrations with all the major mailing services, PHP mail drivers, as well as notifications for multi-channel message delivery. This significantly simplifies the implementation of notifications and mailing.
- Simple data caching. Laravel offers memory caching with Redis, Memcached, and other popular caching tools out of the box through a built-in file cache driver.
- Convenient log handling. Laravel supports multiple log handlers and enables exception/error handling by default.
- Extensive testing. Laravel enables in-depth unit testing due to the built-in PHPUnit support and a preconfigured phpunit.xml file. It also provides user simulation functionality like form input, link clicks, application requests, etc.
But there are some downsides to Laravel, too:
- Steep learning curve. Laravel is simple to learn but hard to master. Lots of functions are overly complicated and work in one way only, and it’s hard to figure them out on your own. So while there are many Laravel developers, few of them are actually able to use Laravel to its full potential.
- No built-in support. Laravel undergoes some growth pains. For example, version 5 is very much different from version 4, and there can be no seamless transition between the two. Since there is little to no built-in support in the framework, the developers have to constantly wade through the Laravel developer documentation.
Despite this, Laravel is definitely the best choice for building PHP apps thanks to being a robust, powerful, and feature-rich MVC framework.
Notable mention: There’s also the Zend framework, which is perfect for legacy projects while being considered outdated and replaced by Laravel. However, quite a lot of projects run on Zend, which makes it a viable choice still.

Ruby on Rails
The benefits of using Ruby on Rails are:
- Development speed. As RoR comes with a wide variety of built-in plugins and modules, developers can use a lot of them when creating apps. This significantly reduces the time needed to write boilerplate code.
- Consistency. Thanks to following the standards mentioned above, RoR enables programmers to standardize most development aspects, like file storage. This helps keep projects transparent and consistent while reducing the development complexity.
- Cost-efficiency. Ruby on Rails is an open-source framework, so it’s completely free to use. To obtain additional capabilities, you can buy Gems — purpose-built modules from GitHub, but most RoR developers have them already, so you don’t have to pay a thing for licensing.
But the downsides of Ruby on Rails development include:
- Runtime performance. While various response speed and database request benchmarks might show that Ruby on Rails does not perform as well as Django, this is not a major limitation. If you’re not planning to handle millions of requests per second like Twitter, RoR will do just fine. Besides, in the majority of cases, server architecture and network infrastructure will become bottlenecks much sooner than the framework capabilities themselves.
- Rigid dependencies. Since many RoR functions are standardized, dependencies between them are also strictly defined. RoR can be configured in one way and one way only in order to run. This immensely speeds up the development of standard features but might limit your flexibility when implementing unique functions.
- High cost of mistakes. Once again, adjusting some architectural decisions mid-project is pretty costly with RoR, as due to its standardized structure, the dependencies between various components are strong. For example, heavy usage of Active Record will result in great dependency on database models that can be detrimental to application performance at scale in the future.
All in all, Ruby on Rails is an excellent choice for the quick development of various mainstream apps that have standard features.
Spring Boot for Java
Spring framework is an open-source inversion of control container for developing apps using Java EE. It significantly reduces the effort of developing web-based Java applications. The framework can boast of embedded support for Tomcat, Jetty, and Undertow. It also provides easy management of dependencies and profile-specific properties.
The benefits of using Spring include:
- Lazy initialization. Developers can greatly cut the time needed for an app to start due to preconfiguring beans based on requirements.
- No boilerplate configuration. Due to the specifics of Java, there is no need for boilerplate code development at all.
- Automated app health checks. A built-in Liveness state constantly checks if the app is responsive and able to perform its functions. If not, it automatically restarts, providing a seamless and satisfying user experience without crashes.
You should also consider the disadvantages of Spring development:
- Complexity. The scourge of all Java development, excessive configuration complexity is a challenge Spring developers must overcome. This can slow down the development process.
- Parallel mechanisms. Spring offers a wide variety of choices for reaching various goals, and selecting the best one from the start is not always obvious. This might result in the need for code refactoring.
Generally speaking, Spring will be a great tool in the hands of experienced Java developers but can be quite punishing if used without prior in-depth consideration.
ASP.NET for Windows and .NET
ASP.NET Core is an open-source modular network created in cooperation between Windows and .NET Foundation. It is the de-facto golden standard for developing .NET applications and works with a plethora of tools across the .NET framework ecosystem. It uses C# code to deliver a consistent and positive user experience on Windows, Linux, and Mac platforms.
Here are the advantages of ASP.NET development:
- Less coding. Developers have to implement fewer statements and can rely heavily on preconfigured functions with ASP.NET Core, which speeds up app development.
- Cross-platform. This framework uses the same C# codebase to deliver a smooth and predictable user experience across several major platforms.
- Swift maintenance. Experienced .NET developers can optimize the Core framework with just a few statements to ensure top app performance and maintainability.
But don’t forget about the shortcomings of ASP.NET:
- Vendor lock-in. Since Microsoft controls the .NET framework, developers have less control over their actions and must follow the limitations imposed by the Core developers.
- Licensing. Unlike pure open-source frameworks, some essential Core modules like Visual Basic come with licensing costs. If you need more advanced functionality, the costs can stack up fast.
ASP.NET Core is the go-to framework for developing Windows and .NET-based web and mobile applications as it ensures a smooth and frictionless cross-platform experience for users.
This covers the five most popular backend frameworks, but there are many more languages and alternatives out there, so the final decision depends on your project’s unique requirements. Just keep in mind that the framework you choose must be convenient and usable for your team, allow creating clean code, and easily update without crashing your app in the process.

4 best backend frameworks for mobile app development
Below is Acropolium’s list of the most popular backend frameworks for mobile apps built for iPhone and Android users. Because they are leading the pack, we will not cover backend frameworks for Windows and Blackberry.
This list of mobile backend frameworks is not exhaustive; it’s just a showcase of the most common options. And here’s a fun fact: Python/Django, Ruby on Rails, React/React Native, and PHP/Laravel can easily serve as backend frameworks for mobile development too.
Flutter is an open-source platform built on the Dart language, which is quickly gaining popularity. Its main features are just-in-time code execution, on-the-go rendering without an interim layer, and design-specific widgets to interact with machine code. All of these ensure rapid development of cross-platform apps that work not only on iOS and Android — Flutter covers Windows, Linux, Mac, and Google Fuchsia as well.
The pros of using Flutter are:
- Hot reload. Flutter engine allows applying your code changes to a running app without the need to reboot it every time to test each little update. This shaves off a considerable chunk of development time and helps keep developers sane and motivated.
- Design widgets. Flutter provides custom widgets for working with many platforms (from Google’s Material Design to Cupertino for iOS Human Interface Guidelines), so a single codebase runs everywhere equally well.
- Concise development. You get a significantly shorter time to market, not only because of a single codebase but also thanks to the many small features and Flutter development tools that allow developers to create a much cleaner, simpler, and concise code.
There are more benefits, but for brevity’s sake, we will just say that Flutter is a future-proof framework that allows you to create beautiful apps for many devices and OSs.
What about the downsides? Flutter has a few:
- Not too native. While Flutter apps look and run equally well on any platform, they don’t exactly have the native look and feel. This is mostly something only iOS purists will notice, but still, it’s worth a mention.
- Pretty young. Flutter is only several years old and is evolving rapidly. There always is a possibility it will evolve in some strange ways, though Google’s continuous support makes this far less likely to happen.
- Compatibility. As new iOS and Android features get released and their SDKs updated, Flutter gets overhauls every time. This might pose the reverse compatibility issues we discussed earlier. But once again, being everyone’s favorite toy right now, strongly backed by Google, Flutter receives updates as frequently as possible to ensure Flutter apps don’t break.
All this makes Flutter a great choice for quickly building robust cross-platform apps, even if they don’t have a fully native look and feel.
Google Firebase is the flagship offering for developing mobile and web apps by Google. And since it’s a cloud-based vendor-specific offering with multiple advantages and just two disadvantages — vendor lock-in and pricing — we’re not going to dive into the details of its pros and cons.
Firebase comes with Google-based services for real-time database access, crash reporting, cloud storage, authentication, etc. Even with a free plan, Firebase provides everything needed for a web/mobile app to function.
When developing iOS apps, you need to ensure the following functionality:
- Real-time database access
- Live synchronization across all devices
- Email and push notifications
- Social login
- API console
- In-depth analytics
All of these are supported by Firebase, which makes it one of the best cloud-hosted backend development frameworks for mobile apps.
Express/Koa for Node.js
If you prefer building a cross-platform app, Node.js can be the best choice. It’s an open-source part of a bigger JS bundle, meaning you will have plenty of tools to work with when developing both the frontend and backend parts of your mobile application. Express and Koa are mobile backend development frameworks for Node.js.
They are pretty similar, so we will cover only Express, which is a MEAN backend development framework coupled with Angular.js frontend and MongoDB database to ensure feature-rich and stable app performance.
The benefits of Express include:
And here are some Express shortcomings:
- Low computing power. Node.js apps have to interpret the code into machine code every time, which means they don’t handle resource-intensive tasks very well.
- Asynchronous programming. This Node.js feature can make it relatively hard to maintain the app code across a variety of devices and browser versions, and the issue might require a lot of development effort to handle.
In the end, Express and Koa can be good choices for the rapid development of cross-platform mobile apps using Node.js.
Back in 2018, React Native underwent a major effort to re-architecture the framework in order to make it more versatile and get rid of its shortcomings.
The benefits of using React Native:
- Reference to C# Host Objects. RN can now directly invoke native modules, omitting the interim rendering layer, which greatly improves the performance of your applications.
- Rapid development with a shared codebase. “Write once, use everywhere” is a JS paradigm, ensuring new apps are developed very quickly and share the same codebase across all platforms.
- Visibility. It’s easy to publish RN apps both to Play Market and App Store.
But we also need to mention the disadvantages of RN:
- Complex updates. It’s pretty complicated to update RN to the latest version, which implores complex update processes for your apps.
- Exclusivity. When developing a web app using RN, you cannot use any libraries for native modules, so brace yourself for lots of custom development.
- No complicated designs. Remember about the Jack of all trades? If you need complex designs or multi-layer interactions in your app, RN has very few tools to work with, so better to go for a native framework.
All in all, React Native is a decent choice for building cross-platform apps with a near-native user experience.
As you can see, there are quite a lot of backend frameworks for web development as well as for building mobile apps. Choosing the best one for your project can be challenging, and hiring actual professionals to deliver the best product is no easy feat. This is where BaaS or Backend-as-a-Service comes into play.

BaaS as an alternative
BaaS is an approach to delegating backend services to a hosted solution. So instead of configuring a web server and a database, managing users, their restrictions, and much more, you simply upload the required code to a hosted platform, configure permissions, and receive all the functionality you need from a BaaS provider.
This way, you save time and money as no design, development, testing, release, and maintenance of the backend engine are involved. Along with the “low code” approach, BaaS allows businesses to not build an airship to deliver a single package.
You can concentrate on growing your business and developing the frontend part of your app while a reliable partner gets things done under the hood.
The real question is, how to choose such a partner?
