Planner vs. Trello: Comparison with Pros and Cons

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.
