What do you like best?
Codacy checks our scala code for dumb (and not-so-dumb) mistakes. The score, while it might not be perfect, is still an excellent indicator.
What do you dislike?
The rules can be..challenging.
The fact that it's a service makes it slightly harder to break our build with a Codacy score than I'd like with a self-contained tool.
Recommendations to others considering the product
They only scan certain code types. Make sure your evaluation period exercises what they do.
When you have problems, don't hesitate to engage the Codacy team. They're very helpful.
What business problems are you solving with the product? What benefits have you realized?
We're looking for quality and speed. Codacy totally gives us both, with the safety of their service providing a good net as well as third-party evaluations. We simply don't release code that doesn't have an "A" score from Codacy.
