We use GitHub.com with private repository. We have over a dozen of projects but most are analyzed through a CI pipeline.
Yesterday we have a new repo that was created but we have not added a CI pipeline with the Sonar Runner yet. In the past we were able to see the project show up in SonarCloud and let have it perform an automatic analysis so we could check for defects early on in the project.
All the code is Go, so there should be no issue to get it analyzed without a runner. We manually added the project on Sonar but we are not seeing the option for automatic analysis.
On the GitHub side the Sonar Application is configure to access all the repositories.
