With the velocity of software development in the modern digital age, code reviews have become an essential part of the process. The best code review tools help maintain the integrity of software products with top-notch code quality while helping organizations ship code faster.
This enables organizations to maintain a tight and coherent pull request process while simultaneously efficiently handling the burden of technical debt.
In this article, I've tested and reviewed the best code review tools on the market today. Keep reading to find tool summaries, screenshots, pricing information, and pros and cons.
What are Code Review Tools?
Code review tools are a type of software application that helps developers to analyze and review the code for any type of project. They help to identify flaws and errors, measure quality and compliance levels, improve coding standards, and reduce the time needed for manual reviews.
These tools are becoming increasingly popular as their features enable developers to easily identify potential problems before they become costly in terms of time, money, or reputation. Code review tools provide enhanced visibility into code development cycles and allow teams to efficiently detect potential security risks, performance issues, incorrect logic flows, and syntax errors.
They can also enforce coding standards with integrated validation rules, which ensure that all code meets certain predefined criteria before it is deployed. Ultimately, these tools assist in creating more reliable systems by promoting collaboration between developers who can share feedback on the overall design process.
