Best Free Code Review Tools of 2025 - Page 2

The Code Registry is an innovative platform that harnesses AI for code intelligence and analysis, providing companies and non-technical users with complete insight into their software codebase, regardless of their coding experience. By linking your code repository—such as GitHub, GitLab, Bitbucket, or Azure DevOps—or by uploading a compressed archive, the platform establishes a secure "IP Vault" and conducts an extensive automated evaluation of the entire codebase. This analysis generates various reports and dashboards that include a code-complexity score to assess the intricacy and maintainability of the code, an open-source component evaluation that identifies dependencies, licensing issues, and outdated or vulnerable libraries, as well as a security assessment that pinpoints potential vulnerabilities, insecure configurations, or risky dependencies. Additionally, it provides a “cost-to-replicate” valuation, which estimates the resources and effort required to recreate or substitute the software entirely. Ultimately, the platform equips users with the necessary tools to enhance their understanding of code quality and security, thereby fostering more informed decision-making in software development.

Codacy is an automated code review tool. It helps identify problems through static code analysis. This allows engineering teams to save time and tackle technical debt. Codacy seamlessly integrates with your existing workflows on Git provider as well as with Slack and JIRA or using Webhooks. Each commit and pull-request includes notifications about security issues, code coverage, duplicate code, and code complexity. Advanced code metrics provide insight into the health of a project as well as team performance and other metrics. The Codacy CLI allows you to run Codacy code analysis locally. This allows teams to see Codacy results without needing to check their Git provider, or the Codacy app. Codacy supports more than 30 programming languages and is available in free open source and enterprise versions (cloud or self-hosted).

Examine both the previous and current iterations of files while utilizing syntax highlighting to identify color-coded discrepancies. Engage in discussions about particular segments with colleagues to ensure appropriate modifications are made. Gerrit offers Git-enabled SSH and HTTPS servers that work seamlessly with a variety of Git clients. It streamlines the administration process by allowing the hosting of multiple Git repositories in a single location. Additionally, it allows for the scheduling of git garbage collection across all managed repositories and supports replication to geographically distributed mirrors, thus enhancing speed and providing backup servers for redundancy during hot spare situations. Furthermore, the Gerrit Code Review platform is adaptable and can be expanded through the installation of server-side plugins, and developers can explore the source code for these additional plugins through the project's listings. This flexibility makes Gerrit a powerful tool for collaborative software development and version control management.

Quickly assess the overall code quality of your project, examine recent commits, and identify the most problematic files with CodeFactor.
