The Best Ten Backend Languages

The Best Ten Backend Languages
Best Ten Backend Languages

Although the users have access to the front end of the application, it affects the application or software’s success or failure. What is more effective on the software’s success or failure is the application or software’s backend. It is because it is the brains of the application, and it adds small functionality to the application.

It is one of the biggest reasons why more and more backend development languages are getting popular for creating different types of applications.

Due to this issue, whenever a professional application is going to be developed, the IT department carefully analyzes the requirements and then decides to use the backend programming language.

When the right backend technology is selected, it helps in the easy development process and brings the following benefits along with it.

  • The speed of development has increased.
  • The application supports scalability options.
  • The responsiveness of the application is exceptionally better.

Although it is a great thing to use the best backend technology in terms of compatibility, selecting one is not easy. It requires a lot of hard work to know which language might be the best for any software application.

So, we have selected the best ten backend technologies that you can use for your ease, and we have defined them so you can compare them to your requirements. By this, when you select the right language, you can develop an excellent functioning backend for your software in no time.

What is an application Backend?

Before directly jumping on to the languages, you must know a little about your application’s backend. So, here we will discuss the backend of your application and its working.

When we look at the software and applications from a developer’s perspective, we can see many things going on. There is a front end, and then there is a back end.

The logic is present, and everything like server-side operations and database functions has handled the backend. Although the front end is visible when you develop an application, most application functionality is under the backend.

Despite being the central part of the software or an application, the backend is not visible to the end-user, and the reason for this is that the frontend is made to make things look less complex and easier to use.

To better understand the backend concepts, please read the article What is a Backend and dig deep into this topic.

A word about programming languages

As our brain can understand and process some languages that we have learned over the years, the same is the case with the computer’s brain. It can break down some languages into sets of commands and then process those commands.

Those languages that are converted into sets of commands are called programming languages. These are used with specific compilers and syntax to let the computer process them.

Types of programming languages

There are two main types of programming languages, and here are the details about each of them.

High-level programming language

It is the language that has easier words for our understanding. Most of the words are commonly used in our daily conversation, so this type of language is elementary to understand, read, and examine. Here, a compiler and assembler work to translate this code to machine code that the CPU can process.

Low-level programming language

These are the languages that are directly understandable for the machine, so these are also called machine languages. These are themselves sets of commands that the compiler has to follow. However, here assembler translates these commands into machine code that is processed by the CPU.

The ten best backend programming technologies

Although there are many backend programming languages available right now, all of them are not good. So, we have selected the best ten languages that you can use for your application development process, and we also have sorted out their features and limitations. So, the following are the ten best backend development languages that you can use.

JavaScript is one of the most popular backend languages in the past decade. It is a scripting language and allows developers to make frontend and backend with the same syntax that significantly reduces workload.

The Express.JS and Node.js allow the management and running of both ends of the application, while APIs help in the quicker and easier development of applications.


Quick developmentUsing the same syntax for both the front end and the backend makes JavaScript very easy and quick to develop.
Lenient backend technologyAlthough there is different middleware supported and preferred by JavaScript, there are no restrictions for using them.

JavaScript allows the developers to select and use whichever middleware they want to implement.
Cost-efficientJust because you can use JavaScript for developing both the front end and the back end of the applications, it cuts the development costs significantly.
I/O featuresThe Express.JS and NodeJS allow the programs to handle the I/O requests and notifications from the connected apps.
Open-SourceJavaScript is an open-source technology, which is why a huge community of developers is working on it.

It means that JavaScript will be under constant improvements and active communities of backend and frontend developers for a long time.
Fewer scripting overheadSome of the built-in features enhance the coding efficiency and improve the performance as well.

The features that do this are DOM, hoops, and many more. They also improve lesser scripting overhead.


  • The event-driven functions are very complicated.
  • Most of the programmers using JavaScript are unable to understand the middleware used with it.
  • JavaScript requires MySQL for database services that are very complex and outdated.
  • Most developers do not prefer the freedom that the JavaScript backend framework offers.

5. Java

Java was made in 1991, but it was officially published in 1995, and from that time, it has emerged as one of the best programming languages in the world. It is also ranked as the second-best programming language in the 2021 TIOBE index ranks. Additionally, it is the best option for building mobile apps.


Scalable The development framework of Java allows it to develop applications with the option of scalability.

It is possible because it allows the server side to run several instances at once. It makes it a great backend development technology.
Easy Understand The syntax used in Java programming is very simple and easy to understand.

It is because it is easier to remember keywords. It makes programming, updating, and debugging very easy for developers.
Multi-threading supportedWhen we talk about using web servers, Java is the programming language that can handle different independent thread requests.

It, however, requires a lot of CPU threads to work as well.
Open-source librariesSuppose you are looking for the support of open source libraries.

Then Java is one of the best backend programming languages. It is because it has massive libraries.

These can be used to easily add all the additional server-side features to your application.
It has enhanced security options.Java is a great option if you are looking to build a great system in terms of security.

It is because here the security is very tight. An instance of this is that the Java virtual machine first checks the bytecode to ensure that there are no viruses, and then the process continues.


  • The programming language Java is time-consuming.
  • There is no low-level programming done in Java.
  • There are no commands for garbage data collection.
  • Java is a language that runs better on expensive or high-end systems. It makes Java development very expensive.

6. C#

C-Sharp is one of the most popular languages for making the backend of a system. It is because of its amazing features like the automation on windows servers. Apart from this, it is great because it executes codes very fast. It can also be used for game development and making CLI applications.


Supports cross-platform developmentOne of the best things about C-Sharp is that it supports cross-platform development.

It means that the apps developed using C-Sharp can run on different operating systems.

However, for more information about cross-platform frameworks C-Sharp, you can refer to that article that discusses cross-platform development in detail.
Extensive compatibilityC-Sharp developed application support for backward compatibility.

It makes C-Sharp the best option for the applications that are to be run on older versions of programming frameworks.
Garbage data and values collectionTo reduce the possible errors in the application, C-Sharp has the garbage data and values collection feature.

It collects all the garbage data that could disturb the values during execution. Because of this, the program can provide the best results optimally.
Object-oriented programmingC-Sharp is the language that supports object-oriented programming.

It means that the developers can make good usage of the classes and relationships. It makes the code exceptionally easy to debug, understand, and even reuse.


Although it is a high-level language, this created a problem that the language cannot directly interact with the hardware.

It is not great in terms of compatibility with different systems because you can only install it from a Windows computer.

Additionally, it can only run using the .Net framework. So, we can say that this technology is very inflexible if compared to the latest backend technologies.

Text processingPerl still maintains the POSIX compliance. It means that the text processing functions of Perl are still great.

It also retains the advanced features of processing socket calls.


  • The processing or programs developed in the Perl language are not as good as some other languages.
  • The libraries available in Pearl lack some of the most necessary features.
  • The process of bug fixing in Perl is not as easy, and it is very challenging.
  • If your code is extensive, then it will not only be challenging to handle it, but it will also be very challenging for the system to handle the code.
  • Scalability is not an option available when you use Perl.
  • The speed of application developed on Perl is not that great.
  • It is a costly language because it is an older technology, and there are not many developers available. Additionally, this language takes a lot of time to learn and get a grip on.
  • The libraries available in Perl are not free as you have to pay copying charges for them.

8. C++

We can call this the advanced version of the C language because it is the same, but it has some amazing additions. One of the biggest additions to C++ is that it supports object-oriented programming, and it’s great for data science projects.

It is one of the oldest programming languages, and being a low-level language, it can interact directly with the hardware. It makes it perform very well. The best part is that you can use it to develop the latest systems without missing or lacking any necessary features.


PortabilityOne of the best features of using C++ is that it is portable.

The language can easily work on any different platforms operating systems, and compilers.

It makes C++ great for achieving different tasks.
Object-oriented programmingC++ supports object-oriented programming.

It makes it very easy to create different types of programs and applications.

It also makes it very easy for the developers to fulfill all the application requirements by using its structured programming architecture.
Low-level languageC++ is a low-level language that means it does not require a lot of translation.

In this way, it can easily interact with most of the hardware. It is the reason why it is used for coding most of the system’s hardware features.
Memory management is greatThe memory management done on C++ is great, and this makes the applications coded in C++ very efficient in terms of memory management.

Developers can also control how their coded program accesses the required memory, which makes it even more memory-efficient if coded correctly.


There is no work done on the automatic collection of garbage data or values. The hardware security is not great when using C++. Due to this, if someone wants, they can manipulate the code to interact with the system’s hardware.

9. Kotlin

Kotlin is the backend development language that can be found in Android studio as an option. Although it was created in 2011, it is now taking over Java because now most applications are being developed using it. Another amazing thing is that now it supports cross-framework development, making it more popular and widely accepted.


Less code is required for the developmentKotlin provides a very concise coding environment where very little code can do most of the tasks.

It makes it take very little time to accomplish the tasks.
Java compatibilityThe code requires no margining when used from Java to Kotlin or from Kotlin to Java.

It makes the code works seamlessly, and developers can seamlessly use the codes of different languages to add more functionality to their applications.
Easy to manageThe code of Kotlin is very easy to read, edit, and understand.

It makes it very fast and easy for the developers to manage and update their code.


  • There are not a lot of primitive variable types available in Kotlin. It makes managing variables throughout your code somewhat difficult. It can also cause output issues sometimes.
  • The functions here also have primitive types like traditional languages. It makes it difficult for the developers who are used to other languages.
  • The compilation for android applications is slower if we compare it to that of Java.

10. Scala

Scala is known for its property of combining functional programming and object-oriented programming. It makes it provide very concise code. JVM powers it, and that is the reason for its wide acceptance. Additionally, this language’s static types support keeps the developer free from the hassle of static types.


Easy coding schemeOne great thing about Scala is that it combines the concept of functional programming and object-oriented programming.

It means that you do not have to deal with both of these separately. It makes the programming process very easy.
Java compatibilityAs scale works with JVM, it makes it compatible with the Java programming language.

It means that whether the code is written in whatever language, it will provide the same result.

It makes it a great backend development language for Java developers.
Concise natureScala code has a very concise nature of coding that makes it very easy to maintain.

It makes the development and updating work very hassle-free.


The coding approach of Scala is somewhat unconventional as compared to the traditional languages like Java. It means you might take longer than usual to get a good grip on this language.

Here the object-oriented programming and functional programming are combined. As most developers’ main concepts are based on C++, this combination of object-oriented programming and functional programming might get somewhat difficult for them.
