I know I am going to sound snarky for saying this but it seems like every company that doesn't actually have a game changing idea for a product ends up building some sort of planning tool.
I am not saying that planning tools can't be innovative but most of them are a combination of overly complex and not easy on the eyes.
I am assuming that most people who want to go with a scrum board that is digital are going to use trello https://trello.com/. I again believe even trello is overly complex but at least it's easy to look at.
It'd easier for a repo hosting service provider to provide an integrated planning tool. It'd be easier for customer too. Of course, only when they do it right.
I love Trello, but it's supposed to be generic, and thus, not easy to use it as a Kanban board (limit number of cards per list, etc) out of the box.
