7 Best Code Review Tools for Developers in 2023

7 Best Code Review Tools for Developers in 2023

In recent years, no-code platforms have become more popular among those that do not want to spend time learning how to code.

This allows them to skip the code writing process while still getting the required functionality.

For example, many web design software allows people to create their website without learning HTML.

No code platforms used on the best project management software can also help save time and money while ensuring that a project is completed on schedule.

That said, understanding how code works, what functionality it’s providing, and ensuring it’s optimized as best as possible is still vital in the development world.

For these developers, code review tools are essential.

In addition, since no programmer is an island, even the most experienced developers need help from their team members to create great software.

But working in a team also has its challenges, one of which is code review.

Code review is looking at code and assessing it for quality.

It’s a way to find and fix errors, ensure code quality, and enforce coding standards.

In this article, I review the best code review tools for developers, so you can start using them in your workflow today to improve the quality of your code.

What Are Code Review Tools?

Code review tools are essential for software development teams to improve code quality and collaboration.

By using a code review tool, teams can more easily identify errors and potential issues with their code before it goes into production.

Code review tools also help teams adhere to coding standards and best practices.

A good code review tool automates many code review tasks, making it easier and faster for teams to get feedback on their code changes.

In addition, an integrated document review tool can also help manage and share documentation, graphics, PDFs, and other files for review.

Benefits Of A Code Review Tool

There are many benefits of code review tools, including the following.

Improved Code Quality

Static code analysis can help identify issues with code that can be fixed before the code is deployed.

By using a code review tool, teams can avoid potential problems and improve the quality of their code.

Adherence To Coding Standards

Popular code review tools help teams adhere to coding standards, such as the Google Java Style Guide.

This can help improve code quality and make it more consistent across projects.

Improved Collaboration

Static code analysis tools are excellent for collaboration, allowing team members to see and comment on code changes in real-time.

This can help to improve communication and avoid merging conflicts.

Merge conflicts happen when two team members make conflicting changes to the same file.

The top code review tools ensure that these conflicts are caught early and resolved quickly, so they don’t cause problems later.

Quick Insights Into Code

With many power code review tools, teams can get quick insights into their codebase, making identifying issues and potential problems more manageable.

This can save a lot of time compared to manually reviewing code changes.

Fewer Errors Through Automation

Automated code review tools bringing the software development process into the code review tools help improve the team’s code quality.

Using a code review tool helps improve code quality by automating many of the tasks of code review traditionally undertaken by human coders.

Features Of Code Review Tools

Now that I’ve looked at the benefits of code review tools, let’s look at some of the best features of the best code review tools.

Peer Review

With peer code review, team members can comment on and review code changes in real-time.

This helps to improve collaboration and avoid merge conflicts, as seen before.


Version plugin systems, such as Git, can be used to automatically post-commit code reviews.

This helps improve the efficiency of the code review process by ensuring code is pushed live as needed.

Version Control Systems

One of the most time-consuming code review tasks is manually checking for merge conflicts.

The best code review tools offer version control system (VCS) integration.

As such, configuring your VCS to automatically post-commit code reviews can save time.


Automation comes in many forms, from automatic checking for coding standards to automated testing.

In addition, code maintainability can also fall under the automation umbrella.

This is the code’s ability to be easily changed or updated in the future, and automation ensures that this is the case by automatically checking for code smells.

Code smells are common code patterns that usually indicate a problem.

They can be anything from duplicate code to long methods.

Flexible To Various Programming Languages

Whether it’s Java, Javascript, Python, SQL, or any other popular programming language, the best code review tools will be flexible to accommodate different languages (and needs).

This is important as it means that teams can use the same tool for all their projects, no matter the language being used.

Best Code Review Tools – FAQ

Should One Consider Open-Source Projects?

While an open-source tool might have a lot of features, it might not always be well-maintained.

A good rule of thumb is to check the last update date and the number of commits before deciding if an open-source tool is right for you.

What Are Git Repositories?

Git repositories are simply places where code is stored and managed.

Think of it as a project folder you can access anywhere, anytime, and on any device.

Is A Visual Expert Needed For Code Review?

No, a visual expert is not needed for code review.

Technically, all you need is a text editor and a willingness to make one’s code better.

Using a code diff tool to see the changes made in a commit can also help compare two pieces of code.

What Is An IDE?

IDE stands for an integrated development environment.

It is a software application that provides all the tools necessary for software development.

For example, an IDE might include a text editor, a compiler, and a debugger.

Wrap Up.

Code review is an integral part of the software development process.

It helps to improve code quality by identifying errors, bugs, or vulnerabilities at an early stage.

The best code review tools offer various features that make the code review process more efficient.

Knowing which features to look for can help you choose the best code review tool for your team.
