SonarCloud is very easy to set up, and integrates nicely into your development platform.
It supports a large number of languages, rules, and can be configured to fit your needs.
Teams use it on a daily basis without needing to think of it.
It is also very intuitive and robust, so you will hardly need technical support ; if you need to, the community website is the way to go for quick answers.
SonarCloud is easy to use and integrates seamlessly into existing projects and nearly all CI/CD pipelines. We integrated almost all of our codebases and used it along with the Sonar cloud extension, which made it more powerful.
