SonarSource provides static code analysis for CSS. Based on our own technology, it can find Bugs, Security Vulnerabilities, and Code Smells. As with everything we develop at SonarSource, it was built on the principles of depth, accuracy, and speed.

SonarSource's CSS analysis has a great coverage of well-established quality standards. This capability is available throughout the development chain for automated code review with self-hosted SonarQube or cloud-based SonarCloud.
