What are Code Review Tools?
Code review tools are used by code authors and their peers to collaboratively review source code. These tools provide a variety of ways to accomplish the review process, such as platforms for coders to communicate with each other, document filing systems for feedback, or quality gates for coding standards. Code review tools also provide ways to track version histories and changes to code, giving them some overlap with version control software.
Code review tools help developers more efficiently remove bugs, address defects, confirm new code, and assess code efficacy at the early stages of development. By providing ways for code to be systematically, collaboratively, and asynchronously reviewed, these tools help minimize time and labor spent on bug testing while simultaneously improving product quality and delivery time.
Code review tools typically include features found in the static code analysis and software composition analysis (SCA) tools, namely in their ability to provide automation and structure to code analysis. The primary difference is that code review tools focus primarily on helping developers and code reviewers communicate directly and share resources.

Code Review Tools Comparison
When choosing the best code review tool for you, consider the following:
Version control system (VCS) support. Your VCS will be a primary factor in determining the best code review tool, as these products are often bound to a specific VCS in order to provide a clear and concise review support. By and large, the most popular VCS is Git, but some tools support Mercurial and Apache. If you use a custom VCS, make sure you choose a code review tool flexible enough to support it.
Bundled vs. Standalone Tools. Some code review tools are sold as a standalone product, while others are part of a larger suite of development tools. This comes with two considerations. The first is whether you want just the code review platform, which is better for users who want to incorporate a single new element into their workflow, or an entire range of tools to replace an existing toolset. The second consideration is how well either option will incorporate into your current workflows. For example, if choosing a standalone tool, you’ll want to make sure that it supports and integrates with existing project management or workflow tools.
Automation. Some tools can integrate automation that handle some aspects of the code review process. These automations usually handle code navigation, CI/CD tool integrations, security checks, and bug detection, among others. While this can speed up delivery by cutting down on quality assurance time and simplifying reviews, it requires an understanding which parts of your process can be automated, if any.
Mobile support. Some code review tools have dedicated mobile apps or mobile browser support. This allows reviewers to access assets and perform reviews from smartphones, tablets, and other mobile devices. This could be helpful if your users are away from a primary desktop or laptop for extended periods of time, or if they need to access and test app code directly from the devices they are developing for.
Pricing Information
There are many free code review tools for single users or small teams. Paid plan schemas vary based on the number of users included in the plan and the types of features offered. At the lowest subscription prices, code review tools commonly range between $4 to $29 per user per month.
