The best code review tools to try in 2025

What are code review tools?

Code review tools help developers collaboratively examine code to identify bugs, improve quality, and ensure adherence to coding standards before merging changes into the main codebase. These tools facilitate peer reviews, highlight potential issues, and streamline feedback through comments, suggestions, and version tracking. By integrating with popular version control systems, they enable teams to manage reviews efficiently and maintain a high level of code quality across projects. The best code review tools enhance collaboration, ensure consistency, and reduce the likelihood of errors in production, ultimately contributing to a more reliable and maintainable codebase.
