RuboCop currently has several official & unofficial support channels. For questions, suggestions, and support refer to one of them.

Please, don’t use the support channels to report issues, as this makes them harder to track.


Most internal discussions about the development of RuboCop happen on its gitter channel. You can often find RuboCop’s maintainers there and get some interesting news from the project’s kitchen.

Mailing List

The official mailing list is hosted at Google Groups. It’s a low-traffic list, so don’t be too hesitant to subscribe.


If you’re into IRC you can visit the #rubocop channel on Freenode. It’s not actively monitored by the RuboCop maintainers themselves, but still you can get support from other RuboCop users there.


We’re also encouraging users to ask RuboCop-related questions on StackOverflow.

When doing so you should use the RuboCop tag (ideally combined with the tag ruby).
