SonarQube was originally an open platform for measuring technical debt. SonarSource realized relatively quickly that there was no money in it so they started selling static code analysis.

Many programming languages were initially not or only very rudimentarily supported, including C++. From the initially unsatisfactory C++ support, the cxx plugin was born.

The cxx plugin has always taken a different approach than SonarSource's built-in C++ analysis. The idea was to use tools available in the C++ context and integrate their output into SonarQube. Probably also by the cxx plugin SonarSource was motivated to create own open interfaces (Generic issue import format, Generic test execution report format, Generic test coverage report format, ...).

How many users the cxx plugin (still) has is difficult to find out. Mostly the plugin is downloaded and installed by a few administrators, but eventually used by many.

Can you please give feedback:

• Do you use the cxx plugin?
• Which parts and functionalities do you use?

Thank you very much for your input.
