Ever spent hours meticulously crafting code, only to have it riddled with bugs and inefficiencies in review? Code reviews are essential for maintaining high-quality software, but traditional methods can be cumbersome and time-consuming. That's why code review tools come in handy for efficient, collaborative code refinement.

In any software development process, code review is vital to keep you from shipping ineffective products. To help you pick the code review tools that give you the most utility depending on your work, I’ve evaluated several options for this list, including an overview of each tool’s strengths and weaknesses and the criteria I considered.

What is Code Review?

Code review is an integral part of the quality assurance (QA) process of software development, often occurring after the initial coding phase but before the final testing and deployment. The source code undergoes scrutiny from someone other than the original author. It’s used to identify potential areas for improvement in efficiency and security. The primary goals of code review are to ensure the quality of the software and to improve the skills of all developers involved.

Code review tools facilitate this process in several ways, including automating the review, laying out a structure, and making the code easy for other team members to access.

Overviews of the 12 Best Code Review Tools

These are my favorite code review tools, along with where I’ve found they excel according to my tests. I’ve also included their strengths and weaknesses, as well as a separate section on how I evaluated them.

1. GitHub - Best repository

GitHub is the most popular Git repository host, offering cloud-based services for development teams of all sizes.

Why I Picked GitHub: When I find an issue in a codebase that I can correct, I use pull requests on GitHub to add suggested code and go over it with my fellow team members. When I initiate one, it lets me compare the branch to the base so everyone can see what’s different and, if there’s a consensus, proceed to merge.

GitHub Standout Features and Integrations:

Features I like using for code review in GitHub include the option to initiate review requests. I can specify someone I want to do it or let GitHub suggest one from analyzing historical blame data.

GitHub also has protected branches where only authorized team members can merge code after review, which is useful when working with new developers or ones with little Git experience.
