Go vs C++: Which One Is Best For Your Next Project?

Every developer wants to build the best app. Selecting the right tool and language is crucial to create the best app. There are numerous languages available for developing applications. Go and C++ are the two most frequently used languages. Developers often need clarification about which to choose for their projects. They are unable to decide which is a better option. If you are one among them, here is a detailed exploration of the two languages to help you make the right choice to suit your project. 

Go and C++ – What are they? 

Go or Golang is an open-source programming language developed by Google and launched in 2009. It is one of the favorites of programmers and developers because it is a simple, portable, and fast language with great performance. Its in-built concurrency feature is its biggest plus. 

C++ is a general-purpose oops-based language developed by Bell Labs It is an extension of the C language. It is an old language and its history dates back to 1979. It is popular for flexibility, scalability, portability, and speed. The multithreading feature is its biggest advantage. 

Go and C++ – Similarities 

  • They are simple languages that are easy to learn and use. 
  • Both Go and C++ have memory-safe features. 
  • They are statically written and compiler-based languages. 
  • Both languages have a rich library. 

Golang vs C++ – Differences 


Performance is a crucial factor when choosing a language. 

C++ is popular for its performance. It is able to perform well because of its features like low-level memory manipulation, efficient execution, and direct hardware access. These features make it the right choice for game development, systems programming, and performance-critical applications. 

Golang also is renowned for its efficient performance but it is different. It focuses on simplicity. Its features like garbage collection and runtime contributions contribute to its performance. Golang’s concurrency makes it a wonderful choice for building scalable and concurrent systems. 


  • C++ is an oops-based language whereas Golang is a procedural language.
  • Codes in C++ are lengthy whereas Golang is simple and has no constructors and deconstructors.
  • Moreover, Golang’s syntax is simple and easily readable. Go is celebrated for its clean and simple syntax. There is no clutter because of its minimalist approach. As it promotes readable code, it is suitable for teams with different levels of expertise. C++ has a complex syntax and hence it is difficult to read. Although new upgrades have improved its readability, it still needs to improve. 
  • C++ uses header files. On the other hand, Golang uses packages. 
  • Golang doesn’t have templates whereas C++ has template libraries. 

Concurrency and parallelism 

Concurrency and parallelism are essential for modern applications because most of them handle multiple tasks simultaneously. They have to utilize multicore processors too. 

No language can beat Golang in concurrency and parallelism. Its Goroutines allow developers to write concurrent codes easily and its channels provide a safe way to communicate between Goroutines. Moreover, its CSP-style concurrency makes it easy to develop concurrent software. Hence, it is the most suitable for building applications like web servers that can handle numerous concurrent tasks. 

C++ also supports concurrency with the help of its Standard Template Library and its features like threads. However, it is more manual management and not as efficient as Go. Moreover, the risks of errors are high. 


Speed is important to finish a project on time. 

Golang is faster because of its simple syntax. Moreover, it compiles codes faster with the support of its features like garbage collectors, Goroutines, concurrency, and multicore CPUs. C++ uses threads for compilation whereas Golang uses channels. This too is a reason for Golang’s speed. 

Ecosystem and libraries 

Libraries and tools affect the ease of use and development speed to a large extent. 

C++ has a rich set of libraries and frameworks for a variety of domains including graphics, game development, scientific computing, and many more. However, it can be challenging to manage compatibility and dependency. 

On the other hand, Go’s ecosystem is more focused on scalability and efficiency. It simplifies dependency management and so, it allows the developers to start quickly. Moreover, its tools and packages are for microservices and web development. 

Memory management and safety

Memory management is significant for software development because unhandled memory issues can result in performance bottlenecks, security risks, and crashes. 

Golang provides automatic memory management with its garbage collector. This feature simplifies memory management and reduces the risks of memory-related bugs. 

C++ provides fine-grained control over memory. This ensures efficient utilization of resources. However, it comes with the risk of increased complexity and more chances of memory-related bugs. 


Buffer overflow is one of the major problems of C++. Security vulnerabilities take advantage of it. When a buffer is overloaded it can end in a crash and can give access to security flaws. 

Go has features to avoid this problem. Programmers use them to prevent overflows. 

Here is a table comparing Go and C++

Aspect  Golang  C++ 
Origin  2007 by Google  1979 by Bell Labs 
Memory Management  Automatic  Manual 
Concurrency  Built-in support with channels and Goroutines Supports with its threads and libraries 
Syntax  Simple  Complex 
Learning curve  Easier to learn and read  Steep learning curve 
Library  Focused on simplicity and has fewer in-built features  Rich standard library with many features
Memory safety  Designed for memory safety  Prone to memory errors 
Speed  Faster  Slower 

Both languages have their strengths and weaknesses. The best choice for your next project depends on various factors complexity of the project, the expertise of the team, performance requirements, etc. However, Golang is an excellent choice for projects that need memory management, concurrency, speed of development, etc. It is a modern approach and useful to boost scalability and productivity. 

If you feel Golang will be the right choice for your next project, hire Golang developer after thorough research. Make sure you hire the best because you deserve nothing less than it.
