Thank you for your question, Yvette!
As we deal with static analysis we are faced with two big issues: the high number of issues found and having results that don't matter. This is how we raise the bar gradually:
First, you can very easily select the rules that you want to enforce in our interface. We always recommend to start with a few and increase it over time. You can also easily ignore issues that don't matter for your project.
Second, as our product really focuses on new issues introduced you can only focus on your new issues introduced and not necessarily on all your existing technical debt.
Regarding specific features that could just be turned off: that's not really possible for the moment. Of course, you don't need to integrate our tool with all your tools or turn on your code coverage report.
But in general we try to build an easy and simple product that we also love to use daily
Our product is also very friendly for more junior developers. They often use Codacy to get immediate feedback on new commits and learn the best practices of a language on their own.
