Top Recommended Replacements
SonarQube / SonarCloud
FREETop Professional Alternative
Why we like it
The global standard for code quality and security; 100% free community edition; excellent for catching 'Code Smells' and bugs alongside vulnerabilities; provides a clear 'Quality Gate' for PRs.
Keep in mind
Lacks native SCA (dependency scanning) and DAST; requires manual configuration of third-party plugins for full supply chain security.
Semgrep
FREEBest for High-Speed Development
Why we like it
Incredibly fast scanning (seconds, not minutes); highly customizable rules using a simple YAML syntax; unified SAST, SCA, and Secrets detection; excellent developer experience (DX).
Keep in mind
The Pro version (with proprietary rules) can become expensive; some deep data-flow analysis is not as mature as Checkmarx's engine.
Snyk
FREEBest Developer-First Choice
Why we like it
Superior open-source dependency (SCA) and container scanning; automated fix pull requests; very low friction for developers; massive database of vulnerabilities.
Keep in mind
Pricing can escalate quickly with usage; enterprise features like 'Snyk AppRisk' require significant upgrades; less depth in specialized API security than Checkmarx.
OWASP ZAP (ZAPROXY)
FREEBest for Dynamic Testing (DAST)
Why we like it
The most widely used DAST tool in the world; 100% free; powerful automated scanners; excellent for manual penetration testing and API probing.
Keep in mind
Lacks the unified dashboard and 'Fusion' correlation found in commercial platforms like Checkmarx One.
