Why teams choose SonarQube for Javascript
AI-ready development
Ship Javascript code faster with consistent quality and security checks for human and AI-written work, giving developers quicker feedback and the business more predictable delivery.
Code quality
Catch bugs, code smells, and maintainability issues in Javascript early so developers fix less later, teams stay consistent, and the business lowers long-term maintenance costs.
Code review
Analyze every Javascript pull request before merge so developers catch issues in context, teams reduce manual review time, and the business ships with fewer regressions.
Code verification
Verify Javascript code in the IDE and CI so developers get fast feedback, teams enforce shared standards, and the business avoids expensive late-stage fixes.
Security testing
Find Javascript security issues before release so developers fix risks earlier, teams improve application security at scale, and the business reduces exposure and remediation cost.
Open source & secrets
Extend Javascript security beyond first-party code with dependency and secret checks where supported, helping teams reduce risk while keeping delivery efficient and controlled.
