Top Backend Frameworks & Technologies for Web Development


There are multiple back-end frameworks you can use in 2021, but we’ve compiled the list of top back-end technologies to consider this autumn.

What are the Most Popular Backend Frameworks in 2021?

.Net Core

.NET Core is an optimized version of the traditional .NET framework by Microsoft. This framework is a great combination of components for development with minimal overheads, which allows .NET developers to retain flexibility while building applications deployed to the cloud or on-premise.

Reasons Why .NET Core Is Popular

  • Open-source framework
  • Cross-platform support
  • The sophisticated feature stack
  • High performance
  • Simplicity of development
  • Versatility and flexibility of app development

What are .NET Core Pros?

  • The new version of Microsoft’s framework is now compatible with Windows, macOS, Linux, and other operating systems.
  • .NET Core is supported by Microsoft, which guarantees long-term investments in its development.
  • It makes it easy to identify defects as C# is a strongly typed language.
  • Web API, integrated with Swagger, simplifies the work with the product for other developers as the code generates the documentation automatically.
  • The .NET Core platform is open-source, which boosts the framework development and improvement.
  • Asynchronous programming patterns utilized by ASP.NET Core improves the overall framework performance.

What Are .NET Core Cons?

  • Though there are many .NET developers, the .NET Core framework requires extra effort and time to learn.
  • There’s Visual Studio for Mac, but still, there are more tools that work better for Windows.


Another top back-end framework in 2021 is Laravel created by Taylor Otwell and released in 2011. This PHP-based back-end framework can be used for websites and web apps based on object-oriented programming principles and the MVC architecture. The framework offers a large variety of in-built development tools, so Laravel development projects may include software solutions of any complexity.

Reasons Why Laravel Is Popular

  • It offers a simple authorization logic.
  • It has Object-Oriented libraries.
  • Laravel has a built-in tool Artisan for automating repetitive tasks.
  • It supports the MVC structure.
  • Laravel has built-in security.

What Are Laravel Pros?

  • Due to thorough documentation and PHP screencasts, Laravel is one of the easiest frameworks to learn.
  • The Model View Controller structure allows writing both PHP and HTML code in the same file.
  • The blade template engine makes it easier to scale applications with new features.
  • Laravel-based web applications perform fast.

What Are Laravel Cons?

  • Being a relatively new framework, Laravel doesn’t have widespread community support compared to some other platforms.
  • It’s quite difficult to transform legacy systems to Laravel.

Spring and Spring Boot

Spring and Spring Boot are also among the widely used web development back-end frameworks. Spring is an open-source framework typically used to develop enterprise applications, while Spring Boot is created on top of the conventional Spring framework and is used to build REST APIs. Though Spring Boot doesn’t have any precise programming model, Spring Boot development is popular on the market.

Reasons Why Spring (Spring Boot) is Popular

  • Developer-friendly features
  • Integration with front-end technologies
  • Aspect-oriented programming
  • Model-View-Controller framework
  • Simple learning curve compared to other platforms

What Are Spring Pros?

  • The POJO model used by Spring is rather lightweight.
  • Spring supports declarative programming and various configuration methods.
  • Spring Boot has a large community and training programs, which makes it easier to start web development with this framework.
  • Multiple features of Spring Boot like auto-configuration saves developers the hassle of
  • coding and useless configuration.

What Are Spring Cons?

  • Spring Boot creates many unused dependencies, so the deployment file may be large.
  • The process of converting legacy or existing Spring applications to Spring Boot is complex and time-consuming.


Django is a great high-level framework that includes everything a developer would need for software development. It doesn’t require installing third-party plug-ins, so it’s perfect for building large-scale, database-driven web applications.

Reasons Why Django Is Popular

  • Simple in use and high performance
  • One of the best out-of-the-box security
  • Suitable for web projects of any size
  • Well-established with a supportive community and great documentation

What Are Django Pros?

  • It’s an ideal platform for IoT, AI, and ML applications.
  • Being based on Python, it leverages some of its benefits, including simplicity, productivity, and external library support.
  • Django’s versatility meets the demands of higher traffic and is widely used in such industries as scientific computing, intelligent automation, etc.
  • One of the best things about Django is its active community that contributes to the framework’s user-friendliness and stability.

What Are Django Cons?

  • Many developers admit that Django lacks conventions, which results in a configuration boilerplate and slower development.
  • It’s not suitable for small projects with a few features.
  • It has a steep learning curve as it comes with many features that are difficult to understand for developers.

Node JS

Last but not least top server-side framework in Node.js. While the first version was introduced in 2009, Node.js won the top spot in StackOverflow’s 2020 developer survey. More than half of the respondents used it in their projects. Let’s find out why Node.js development services are still on the rise.

Reasons Why Node.js Is Popular

  • It’s easy to learn Node.js.
  • It’s excellent for scalable applications.
  • It has a cross-platform nature.
  • It’s lightweight and fast.

What Are Node.js Pros?

Real-time applications powered by Node.js have high performance thanks to their ability to multitask.

The framework’s features allow developers to easily scale Node.js-based applications.
It makes the development process more cost-effective as Node.js allows developers to write codes on the front-end and back-end sides.

Node.js has a large community, which means you can get extensive support from other Node.js experts.

It’s easy to learn and adapt for web developers, which makes it one of the most popular back-end frameworks.

Since Node.js offers full-stack capability, it will help you build a cross-functional team.
Node.js saves a lot of coding time and effort due to extensive resources at Github and easy code and data file management powered by client-side and server-side JavaScript.

It reduces load time and re-execution of code with its caching module.

What Are Node.js Cons?

  • Node.js reduces performance when executing heavy CPU-based computing tasks.
  • Its APIs are frequently changed, which forces Node.js users to continually change the access code.
  • It’s difficult to maintain code because of the Asynchronous Programming Model.


There are numerous companies offering back-end development services, but it’s crucial to select the back-end web development framework that will address the challenges of your project. You can choose between a wide variety of frameworks that have their advantages and disadvantages. The choice should rely on your project specifications and the expertise of your developers.
