I’ve made one for myself as well, built as a Chrome extension loaded locally. This way no domain is needed and I did not have to worry about security. It worked well for a while when I was multitasking a lot. My manager was very happy with me taking care of things without missing any details. The problem is that Kanban makes more sense for a team than an individual. If nobody else is using it, it has few advantages compared to simpler solutions, like post-it notes. So I stopped using it eventually.
