SonarCloud is a tool that helps ensure Java pull requests are clean by analyzing and decorating them instantly after creation, making it easier to add new features on top of a clean code base. With SonarCloud, developers can get started in under 3 minutes and set up automatic analysis for their GitHub organization, which is entirely free for open-source projects with access to the full feature-set. Once set up, every pull request will be analyzed and decorated instantly after creation, providing instant feedback on bugs, vulnerabilities, and code smells. This enables systematic remediation of code issues, making code reviews faster and more efficient. By using SonarCloud, developers can improve their code quality and unlock features like taint analysis and code coverage reports in the future.
