Recently I've found that Github Marketplace area has some Continuous Integration tools to build and release software using GitLab, but I didn't find any mention of QuickBuild in there.
According to this resources, there is a common workflow to build a RESTful plugin. What do you think about having QB over there as well ?
I believe many of the "plugin-basis" operations might already been developed in today's QB API. It could be only a matter of adjustment and packing in order to publish something in Github's format. (It's an assumption, ofc.. could also require some archtectural changes I have no knowledge about)
Apps Management - https://developer.github.com/apps/
Requirements for a Plugin to show in the Marketplace area - https://developer.github.com/apps/adding-integrations/listing-apps-on-github-marketplace/requirements-for-listing-an-app-on-github-marketplace/
Thanks and Hope you like the idea!
