I'm looking for a free (as in free beer) Scrum tool that integrates with private GitHub projects. It should also be hosted, there are a few open source (free software) projects out there but I don't want to spend too much time setting up and maintaining such tools.
Jetbrains has a free plan but only for public projects. Others like Pivotal Tracker are only free for 30 days, but that's not enough time to get a good idea. I'd be ok with it if it were free for one year.
I've used ScrumDo in the past but 20$/month is not an option for a bootstrapping startup project.
