Another kanban tool to consider is Codecks[0], which I learned about here on HN. We liked it so much we moved from Trello. It's marketed for game devs (which I think is a mistake!) but it's a powerful tool for any kind of small team (we use it for enterprise software dev) and also has a free plan.<p>[0] <a href="http://codecks.io" rel="nofollow">http://codecks.io</a>
