Phabricator is an open source code review tool developed at Facebook, that integrates with git, Mercurial, and svn. Gerrit workflows provide strong quality and security gates by blocking commits until they are reviewed so that teams can be confident that all code is reviewed before itвЂ™s added to the repository. It also enables easy workflow management with integrated access controls that can be delegated. It helps users to collaborate and discuss code changes by providing syntax highlighting and colored differences to help them compare old and new versions of files, allowing comments on every single line of code added. Gerrit is an open source web based git code review tool originally developed by Google over their Git version control system. It also supports collaboration by allowing users to comment inline and request peer reviews. Users can preview changes, and track history by browsing commits, comments, and references related to their pull requests.

This is often a go-to solution for developers that are already managing their codebase on GitHub, since lightweight code review tools are built into every pull request, enabling developers to seamlessly integrate code reviews into their workflow. GitHub, the pioneer of the pull request, is also a favorite when it comes to code reviews, offering an inbuilt code review editor.

This allows team members to exchange comments over specific lines of code or discuss changes in general. It also enables users to easily keep track of changes and discussions by providing a unique ID to each code review. It also supports collaboration by making changes visible to the whole team, and enabling teams to engage in technical discussions through effective code reviews. Upsource promises developers that it can help them achieve better code quality, and advance their skills. It supports Java, PHP, JavaScript and Kotlin projects. Upsource is JetBrainвЂ™s code review tool and repository browser, that integrates with git, Mercurial, perforce, and svn. Being part of the Atlassian family, Crucible easily integrates with Jira, Bitbucket Server, Bamboo, and many other tools that are part of the development workflow.Д¬rucible provides developers with the option of pinpointing the issues that they are referring to by commenting inline. It supports SVN, Git, Mercurial, CVS, and Perforce. It enables users to review code, discuss changes, share knowledge, and identify bugs and defects as part of their workflow. This documented history of the code review process is also a great learning resource for newer team members.Д¬hoosing the Right Code Review Tool #1 CrucibleД¬rucible is AtlassianвЂ™s enterprise-level collaborative code review tool. This reduces friction between teams and also saves a lot of valuable time by providing team members with a platform for discussion and decision-making.ДЄnother feature that many code review tools provide is the ability to save and view the history of a bug or defect, making it easy to document, track, and share knowledge. Code review tools help ensure that ownership over code quality and security is shared, and that each voice is heard and addressed. Using a code review tool can help teams ensure that a continuous code review process is in place, that all the code review steps are implemented by the relevant team members, and that issues are tracked and resolved.Д¬ode review also helps support collaboration between team members and across teams which is another important component of DevSecOps practices. The Benefits of an Automated Code Review ToolДЄpart from speeding up the development process, there are many additional advantages to using an automated code review tool. Human error is a natural part of the development process, and code review tools help ensure that those errors are addressed swiftly. Happily, along with the many automated DevSecOps tools on the market, code review tools can help teams collaborate and track changes easily throughout their code review process. Code review is essential for detecting and remediating code defects and errors before production, when they are relatively easy and less expensive to address.

But even before testing the code comes code review, beginning at the earliest stages of development. Shifting left quality and security testing has finally become a practice that organizations are embracing.
