PMD vs Snyk: What are the differences?
# Introduction
PMD and Snyk are both tools used in the field of software development for different purposes.
1. **Code Analysis Focus**:
PMD primarily focuses on performing static code analysis to identify common programming flaws and maintainability issues in code, whereas Snyk specializes in identifying and fixing security vulnerabilities in open source dependencies.
2. **Language Support**:
PMD supports a wide range of programming languages including Java, JavaScript, XML, and more, while Snyk is mainly focused on supporting JavaScript, Node.js, Python, and Ruby.
3. **Security Emphasis**:
Snyk places a strong emphasis on security by continuously monitoring dependencies for known vulnerabilities and providing actionable insights to developers, whereas PMD's primary focus is on code quality and maintainability.
4. **Integration with CI/CD Pipelines**:
Snyk can easily be integrated into Continuous Integration/Continuous Deployment pipelines to automate security checks, while PMD can also be integrated but is more commonly used as a standalone code analysis tool.
5. **Remediation Recommendations**:
Snyk not only identifies vulnerabilities but also provides specific remediation advice and patches to fix security issues, whereas PMD mainly points out coding issues and leaves the resolution up to developers.
6. **Pricing Model**:
Snyk offers a freemium pricing model where basic functionalities are available for free with premium features requiring a subscription, whereas PMD is an open-source tool available for free without any premium features.
In Summary, PMD and Snyk serve different purposes in software development with PMD focusing on code analysis and maintainability, while Snyk specializes in identifying and fixing security vulnerabilities in open source dependencies.
I'm beginning to research the right way to better integrate how we achieve SCA / shift-left / SecureDevOps / secure software supply chain. If you use or have evaluated WhiteSource, Snyk, Sonatype Nexus, SonarQube or similar, I would very much appreciate your perspective on strengths and weaknesses and how you selected your ultimate solution. I want to integrate with GitLab CI.
I'd recommend Snyk since it provides an IDE extension for Developers, SAST, auto PR security fixes, container, IaC and includes open source scanning as well. I like their scoring method as well for better prioritization. I was able to remove most of the containers and cli tools I had in my pipelines since Snyk covers secrets, vulns, security and some code cleaning. SAST has false positives but the scoring helps. Also had to spend time putting some training docs but their engineers helped out with content.
