With the move to microservices architecture, a lot of teams end up managing dozens of code repositories (vs just a couple before), and some tasks that were done quickly manually are now becoming very time consuming : consistency of the repositories, and eventually of your platform, gets impacted, making it more and more difficult to manage.
Surely, there must be some tools existing to take care of boring tasks like finding where a given dependency is used, and upgrade it automatically (this is just an example)... Well actually, we didn't find anything, so we implemented them ourselves and made them available for everyone !
