As the Internet of Things (IoT) evolves, it may become more difficult to determine which tools are best suited for specific tasks. Similarly, estimating the relative popularity of programming languages without precise prerequisites can be challenging.

Identifying the top IoT programming languages among 6.2 million developers can be challenging.

According to reports, approximately 30 billion devices will be connected to the Internet by the end of 2025.

Developers want to stay ahead of the competition by upgrading to remain relevant in the future and advance their careers. While many popular languages dominate the IoT space, learning about other languages can help.

There are many languages, and deciding which one can be daunting. Do you need help determining which programming language to use for your IoT projects? Knowing the best programming languages for an IoT project can make it easier to choose one. This article will discuss the programming languages used for the IoT backend. The growing demand for IoT-based necessitates the best IoT App Development NYC by professionals.

What is the purpose of programming language? 

Programming languages allow you to write code or instructions that computers can execute and understand.

 They provide:

  • A means of communication between machines and humans.
  • Allowing the development of software applications.
  • Mobile apps
  • Websites.
  • Other computational tasks. 

Some key uses of programming languages are: 

  • Data Analysis and Machine Learning 
  • Web development 
  • Scripting and Automation 
  • Embedded systems in IOT 
  • Software development 
  • Mobile applications. 
  • Game development 

For example, programming languages are required to develop software and firmware for embedded systems in Internet of Things devices. 

C and C++ are two of the most widely used embedded programming languages due to their efficiency, low-level hardware access, and small memory footprint. They enable developers to write code that controls the operation of microcontrollers, IoT sensors, IoT protocols, actuators, and other components.

What Programming Languages are used for IoT Backend:

The backend application is developed independently because this is an IoT project. Server load, data volumes, and other factors are more important. In this case, the choice will be almost the same, but on the condition that the team must have prior experience working on projects with the complex business logic required for the future server.

Let us mention the top six programming languages for IoT backend development.

1.     Java:

It is the most popular programming language in the world and the most sought-after for backend web development. Furthermore, it is similar to C#, the second most popular backend language. If you understand one, you can easily switch to the other, meaning your skills are relevant for most backend development jobs. Java is an old-school object-oriented programming language that is lengthy but robust.

Java is among the best options for IoT App Development NYC. Its object-oriented nature, low hardware dependency, and hardware support libraries have made it ideal for IoT development.

2.     Python:

Python is also a very popular backend programming language. It is not as popular as Java, but it is still popular enough that there are jobs on the market. Python is the best way to broaden your skill set in machine learning. Furthermore, its concise pseudocode-like syntax makes coding a lot of fun.

Python is a simple, uncomplicated, and versatile language. Its extensive library and toolset make it IoT-compatible. Python is a high-level programming language popular for Internet of Things (IoT) development due to its extensive libraries and ease of use.

3.     Go:

Go is the fastest-rising programming language in the world at the moment. Adoption has risen dramatically in the last year alone. Many experienced web developers now recommend Go. It is the next big thing. It handles concurrency exceptionally well, and many believe it will become more important in web development.

Rob Pike, Ken Thompson, and Robert Griesemer, three well-known Google Software Engineers, invented it in 2007. They developed Golang as an easy-to-learn and highly scalable system programming language.

Go offers concurrency and features to optimize hardware utilization. Its cloud community support and compatibility with other platforms make it a popular language for IoT devices.

4.     Ruby:

Ruby is considered one of the most reliable programming languages. It has a well-documented and thriving community. Most tasks are completed using the Ruby on Rails framework, a powerful framework for developing database backend App Development NYC.

5.     PHP:

Most websites are built with PHP. It is platform-agnostic, fast, and easy to maintain, making it ideal for backend development. 

Currently, the most popular PHP frameworks are Symfony and Laravel. Both are strong PHP frameworks that can be used for various long-term and small-scale development projects.

6.     C#:

C# is a popular language used in various development fields. It is based on C++ but is regarded as a simpler and more convenient alternative. This coding language requires little processing power and can handle errors. C#, like the Net platform, was created by Microsoft and offers excellent technical support.


Anticipate the future evolution and growth of your IoT application. Each project and its tech stack are unique. Although there is some consistency among the top programming languages, IoT development is multilingual. It entails handpicking the best set of technologies based on your project’s specific needs. 

Predicting which programming languages will endure is difficult, but trends can help you see where the market is heading. This is also important for marketing IoT products, as customers prefer systems with user-friendly settings and languages.
