When not to use Golang?

Golang is designed with the sole intent of keeping it more intuitive and user-friendly; however, these characteristics, along with a few other factors, sometimes turn out to be a setback or a contradiction to What is Golang good for, thereby leading to certain circumstances where Golang is not the most viable choice. A few of them are given below:

GUI Applications

Golang has no GUI or Graphic User Interface toolkit in standard libraries like Java or C#. Therefore, product owners must use third-party libraries to build UIs, making your application more complex. So, when aiming for desktop applications with a GUI, you can consider Java or C#, which have their in-built GUI toolkit.

Legacy Systems

Golang is still a relatively new language and is not much viable for maintaining or extending the legacy systems written in other languages. Rewriting an entire system in Golang is a time taking and expensive and, thus, is not worth the effort if the existing system is effectively working. Therefore, it is better to stick with the language used for the legacy systems written or consider a better and more compatible language like Java or Python.

Large Enterprise Applications

Golang is a scalable language regarding pervasive enterprise-level applications needing extensive features and integrations. And as discussed, Golang is a young language with a comparatively smaller ecosystem than languages like Java and Python, which implies that fewer libraries and tools are available within the market to handle complex needs and requirements such as high availability, distributed system, and other enterprise system integration.

Data Analysis and Scientific Computing

Golang possesses a few libraries for data analysis and scientific computing. Still, there may not be better choices for these applications as other tech stacks like Python and R possess more extensive and specialized libraries and frameworks for data analysis and scientific computing, making it the reason data scientists and researchers prefer them. Though Golang offers functionality for these applications, it may not be that convenient compared to Python and R.

Comparing Golang with Other Programming Languages

All programming languages, including Golang, possess specific characteristics that make one different or efficient from others. Below is a comparison of Golang with a few other programming languages to help you decide Why Choose Golang for your next web application development project.

However, Java, on the other hand, is more mature along with a larger ecosystem, thus, making it a more feasible option for developing enterprise-level applications.


When answering, Golang vs Python? Then, Golang takes the lead as it is faster than Java and is also more efficient, thus, making it a better choice for applications needing high performance and scalability. In contrast, Python is easier to learn and has a broader range of libraries and frameworks, thus, enabling better data analysis and scientific computing.


Comparing Golang and C++, the Go language is easier to learn and use, having a simple syntax, memory management, and system. Also, it is more secure with built-in error handling and garbage collection. C++, on the other hand, is faster and more efficient, making it a better option for low-level systems programming.


The reason to choose Golang over Rust is that Golang offers simplicity and user-friendliness for its developers, delivering a simpler programming experience to the product owners. This uniformity and simplicity-centric approach of Golang enhances team efficiency, making it a developer-favored language, whereas Rust presents excellent control over threads and their behavior within the system; however, its complexity and steep learning curve make it less popular among developers.


Compared to Node.js, Golang is lightweight and possesses a performance characteristic similar to that of C/C++; However, both Golang and Node show almost identical results considering real-life performance, database interactions, or net network communication, but Golang presents a consistent performance under all aspects whereas, for Node.js, it either shows an exceptional performance of terrible depending on the application type.
