PullRequest is a full-featured service that can integrate with GitHub, GitLab, Bitbucket and Azure DevOps. It offers both on-demand and continuous code review, including AI-powered tools to find high-risk security vulnerabilities. With customizable workflows and approved reviewers, it's got a strong security focus, with background-checked reviewers and data centers certified for ISO 27001 and FISMA. That makes it a good choice for teams in regulated domains.
SonarCloud is another top contender, supporting more than 30 programming languages and integrating with Azure DevOps. It offers automated analysis, clear quality gates and sophisticated developer security tools like secrets detection and static application security testing. SonarCloud offers immediate feedback and in-context coding advice, so it's a good choice for improving software quality and tackling technical debt.
If you want a more AI-based approach, Trag uses sophisticated AI to try to make code review more efficient. It supports multiple repositories, pull request review and features like semantic code analysis and predictive bug detection. Trag can be set up by linking a GitHub account and adding custom rules, so you can let engineering teams focus on product work instead of reviewing code manually.
