Best code quality tools (2024) 

Coding is a fundamental aspect of software development. Since an increase in the number of complex and high-profile security software projects, coding is becoming an important part of digital transformation as well. 

But, there is a lot more to coding than just writing code and executing it. The developers must know how to write high-quality and clean code and maintain code consistency. As it not only enhances the software but also contributes to a more efficient development process. 

This is why code quality tools are here to your rescue. But, before we suggest you some code quality tools, let’s first understand what ‘Low-quality code’ is and what metrics need to be kept in mind. 

How to define ‘Low-quality code’?

In simple words, low-quality code is like a poorly-written article. 

An article that consists of grammatical errors and disorganized content which, unfortunately, fails to convey the information efficiently. Similarly, low-quality code is poorly structured and lacks adherence to coding best practices. Hence, fails to communicate logic and functions clearly. 

This is why measuring code quality is important. The code quality tools consider the qualitative and quantitative metrics for reviewing the code. 

Let’s take a look at the code metrics for code quality evolution below: 

Qualitative metrics:


The code’s ability to perform error-free operations whenever it runs.


A good-quality code is easy to maintain i.e. adding new features in less time with less effort. 


The same code can be used for other functions and software.


The code is portable when it can run in different environments without any error.


A code is of good quality when a smaller number of tests are required to verify it. 


When the code is easily read and understood. 


The good-quality code should be clear enough to be easily understood by other developers. 


A well-documented code is when a code is both readable and maintainable i.e. Enabling other developers to understand and use it without much time and effort. 


A good quality code takes less time to build and is easy to debug. 


The extensible code can incorporate future changes and growth. 

Quantitative metrics:

A soft sizing algorithm that breaks down your source code into various micro functions. The result is then interpolated into a single score. 

The set of measures to evaluate the computational complexity of a software program. More the complexity, the lower the code quality.

It measures the structural complexity of the code. It is computed using the control flow graph of the program. 

5 best static code analysis tools

5 best dynamic code analysis tools

Dynamic code analysis tools enable you to analyze and test your applications during execution against possible vulnerabilities. 

Choosing what tools fit your requirements could be a bit tricky. As these tools are language-specific and case-specific. You can pick the right tool from an open-source repository by Github based on your current situation. 

However, we have picked 5 popular dynamic code analysis tools that you can take a look at: 

A real-time code coverage tool that provides insights for penetration testing activities.

5 best peer code review tools

Although static and dynamic code analysis tools are effective, they won’t catch everything. Since they aren’t aware of the business practices and functionality you are trying to implement. 

This is when you need another developer from your organization. And this is possible with the peer code review tools. They not only help in making better code but better teams as well. 

A few of the questions that another developer considers are: 

    • Can I find any obvious logic errors in the code? 
    • Are all cases fully implemented based on the current requirements
    • Are the new automated tests enough for the new code? Or do the existing ones need to be rewritten to account for changes in the code
    • Does the new code abide by prevailing style guidelines?

How do Typo help in reviewing the quality of code?

Without sounding boastful, our motivation for creating Typo was to enhance our code review process. With Typo, you have the ability to monitor crucial code review metrics, such as review duration and comprehensiveness. Additionally, it allows you to configure notifications that alert you when a code change is merged without a review or if a review has been unintentionally overlooked. There are three major metrics it tracks – 

  1. Average commits after PR raised – Average number of commits after the PRs are raised
  2. PRs merged without review – Total number of PRs merged without review
  3. Bugs rate – Average number of issues raised against a story point/tasks done

Enhancing development processes goes beyond just increasing speed and quality; it brings predictability to your throughput. By leveraging Typo, you can achieve better performance and planning, ensuring consistent alignment throughout your organization.
