SonarQube (formerly Sonar) is an open-source platform developed by SonarSource for continuous inspection of code quality to perform automatic reviews with static analysis of code to detect bugs, code smells, and security vulnerabilities on 20+ programming languages. SonarQube offers reports on duplicated code, coding standards, unit tests, code coverage, code complexity, comments, bugs, and security vulnerabilities.[
SonarQube can record metrics history and provides evolution graphs. SonarQube provides fully automated analysis and integration with Maven, Ant, Gradle, MSBuild and continuous integration tools (Atlassian Bamboo, Jenkins, Hudson, etc.).
SonarQube integrates with Eclipse, Visual Studio, and IntelliJ IDEA development environments through the SonarLint plug-ins, and also integrates with external tools like LDAP, Active Directory, GitHub, and others. SonarQube is expandable with the use of plug-ins.
