8 Best Code Review Tools for Developers

In this post, I’ll explain code review and explore popular code review tools that help organizations with the code review process.

In recent years, the significance of code review for producing high-performing software has been acknowledged. It is one of the most effective means of preventing security vulnerabilities and faults from entering production.

Similarly, the demand for efficient code review tools has increased. This article is a list of the top code review tools for developers.


What Is the Code Review Process?

A code review process is a systematic way of discovering potential security vulnerabilities and bugs in software code. It entails thoroughly reviewing the source code by one or more programming and software development experts.

Why Is Code Review Important?

There are several reasons why code review is essential for developers:

  • Ensures the codebase’s quality and prevents security flaws and defects early.
  • Aids in identifying program flaws, potential vulnerabilities, and possibilities for improvement.
  • Ensures that the code adheres to the industry’s best practices and coding standards.
  • Aids in detecting and eliminating needless flaws.
  • Facilitates coaching for young programmers.
  • Assists in building a knowledge base about frequent errors and loopholes.

How to Perform a Code Review?

There are multiple techniques for Code Review. Here is a summary of three major code review methods:

Peer Review: In this procedure, the code is examined by a specialist in the same programming language as the original creator. The reviewer will read the code line by line and find any typographical or logical flaws, potential vulnerabilities, or enhancement opportunities.

Static Analysis: In this method, specialized tools are used to analyze the source code for flaws before executing the code. Code review duties can be automated with static analysis tools to ensure adherence to coding standards.

Dynamic Analysis: This method entails executing the software and testing it against known inputs and outputs to identify bugs or problems. Static analysis alone cannot reveal issues discovered by dynamic analysis. It is more than a mere review and can be considered a component of STLC (Software Testing Life Cycle).

What is a Code Review Tool?

A code review tool is a software app that streamlines, integrates, and automates the code review process for developers. It consists of a collection of static code review tools that can automate the activities associated with code review, such as checking for compliance with coding standards.

Why Should You Use Code Review Software?

There are multiple advantages of using code review software:

  • First, streamline the code review process by automating its associated tasks.
  • Facilitates code review integration into the software development process.
  • Third, it offers engineers the ability to collaborate on code reviews.
  • Finally, it brings openness and uniformity to the entire code review process.
  • Facilitates optimization of the QA testing process
  • Documents the complete code review process

Common Features of Code Reviewing Tools

The following are common features seen in leading code review tools:

  • The capacity to organize code reviews according to several attributes, such as tags and pull requests.
  • A system for notifying stakeholders when a change has been made.
  • A commenting mechanism that enables stakeholders to submit feedback and recommendations.
  • The app should support both text and binary files.
  • Multiple version control systems, including Git, SVN, and Mercurial, are supported.
