DOMXSS Scanner is a free static application security testing tool. SonarSource SonarQube is a commercial static application security testing tool by SonarSource. Compare features, ratings, integrations, and community reviews side by side to find the best static application security testing fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Frontend developers and security engineers auditing single-page applications will find DOMXSS Scanner useful for catching DOM XSS issues that static analysis often misses, particularly in JavaScript event handlers and sink chains. The tool is free and requires no setup; paste code and get results in seconds, which beats paying for a commercial SAST license when you're hunting one specific vulnerability class. Skip this if your codebase spans multiple frameworks and you need centralized reporting tied to your CI/CD pipeline; DOMXSS Scanner is a targeted scanner, not a platform.
Development teams shipping code through CI/CD pipelines need SonarQube for its taint analysis, which catches injection vulnerabilities that traditional SAST misses by tracking data flow end-to-end across 35+ languages. The AI CodeFix feature actually reduces remediation time by suggesting context-aware fixes inline, and SOC 2 Type II certification covers the compliance box for most mid-market buyers. Skip this if your priority is runtime detection or if you need secrets scanning as your primary control; SonarQube finds exposed credentials but treats it as a secondary scanner rather than the core value prop.
