Software quality is about a lot more than slinging good code. As a developer you use numerous tools, techniques, frameworks, and processes as you write, organize, build, test, refactor, and continuously improve your applications. Sonar (SonarQube), a free and open source quality platform, makes it radically easier to track, manage, and enhance the overall quality of your code. It leverages respected tools like Findbugs, PMD, and Checkstyle, and implements well-established best practices to provide a full-featured, robust platform for code quality measurement, review, and remediation. Originally Java-only, Sonar now works with many other languages.
