9 Best Code Review Tools for Developers in 2023

Code review is a crucial part of the software development process, where a developer reviews the code written by another developer. It helps to improve the quality of the code and ensure that it is readable, maintainable, and secure.

Manual code review can be time-consuming and error-prone, which is why many developers use code review tools. In this article, we will discuss the best code review tools for developers in 2023.

Code Review Tool

Code review tools are software programs that help developers review and evaluate the code they have written before merging it into the main codebase. These tools provide a way to identify and fix errors, optimize code, and ensure compliance with coding standards and best practices. Some common features of code review tools include:

Code analysis

The tool examines the code for syntax errors, logical errors, and security vulnerabilities.

Code commenting

Reviewers can add comments to the code, suggesting improvements or highlighting potential issues.

Code comparison

The tool provides a side-by-side comparison of the original code and the modified code to highlight the changes made.

Code History

The tool maintains a record of changes made to the code over time.

Code metrics

The tool provides metrics such as code complexity, test coverage, and maintainability.

What Is the Code Review Process?

The primary function is to check new code for bugs or other defects as well as evaluate their performance. This process will be conducted at the end of the project. Developing a code review system shouldn’t just be based on one-way feedback.

Hence, an intangible benefit of implementing code reviews is improved programming knowledge among all members. If you wish to begin the automated code review process for a company, you need to decide first who reviews the code.

During small team assignments, teams may have lead teams review every code. A team that includes multiple reviewers could allow for more efficient code reviews if you want.
