Hi @Just_some_guy,
The rules website lists all the rules available in SonarCloud and either available in the latest version of SonarQube or that will be available in the next release (8.6 in December).
Starting in 8.5, the languages plugins are bundled with the version of SonarQube : New language features now available exclusively in latest SonarQube versions
Which means that, to benefit from all the available rules in your Quality Profile, you should be on the latest version (8.5 currently) and not on the LTS 7.9. And maybe, some of the rules that you see on the rules site will be available only in 8.6.
That being said, could you share a screenshot of the number of rules you have in your Quality Profile?
And did you build your own Quality Profile or are you using the SonarWay by default?
Thanks,
Carine
