The real expense is in integrating with lots of different environments; Roc mentioned that integrations with Github and Travis were already working, but not Gitlab yet. (On the other hand you can do without any integration at all. Take a look at https://github.com/Pernosco/pernosco-submit/; it will upload the source from your computer to your debugging session if it's not cloned from a recognized git/hg host.)
