An update, since I see some upvotes.

I followed @XiZhao's advise and managed to sign up without giving access to github which is very good. If I want to have scans run automatically on github projects, I still have to grant write access. The other option is to run the tests myself, which probably is what someone in a professional setup will do anyway, so I think it is not a very serious issue, although it would be nice to be fixed.

As for my go endeavors, I haven't yet managed to analyze my go projects, but I did have better luck with javascript and scala (gradle) which was very impressive.

Great project overall and I am sure it will be a success, because I know firsthand how cumbersome can be to do this important task manually.
