We are using it as wellas our other software solutions (TeamCity-Continuous Integration Server). Very easy integration both internally within internal applications or externally into Jenkins/SonarQube etc without problems! You can easily use different data sources / connectors so nothing really I dislike about its functionality yet but there might be something new coming up soon which would change my opinion :) Our Teamcity was running outof space because we had more than one project inside TC - now everything runs smoothly since integrated properly via docbrowser!
