[SonarQube](http://www.sonarqube.org/)® software (previously called Sonar) is an open source quality management platform, dedicated to continuously analyze and measure technical quality, from project portfolio to method. If you wish to extend the SonarQube platform with open source plugins, have a look at our [plugin library](https://docs.sonarqube.org/display/PLUG/Plugin+Library).

SonarCloud is the leading product for Continuous Code Quality online, totally free for open-source projects. It supports all major programming languages, including Java, C#, JavaScript, TypeScript, C/C++ and many more. If your code is closed source, SonarCloud also offers a paid plan to run private analyses.

SonarCloud offers end-to-end integrations for teams leveraging [GitHub](/integrations/github/), [VSTS](/integrations/vsts/), or [Bitbucket Cloud](/integrations/bitbucketcloud/) in their development processes.
