Trello is a free web-based project management application made by Fog Creek Software.

Trello uses a paradigm for managing projects known as kanban, a method that had originally been popularized by Toyota in the 1980s for supply chain management. Projects are represented by boards, which contain lists (corresponding to task lists). Lists contain cards (corresponding to tasks). Cards are supposed to progress from one list to the next (via drag-and-drop), for instance mirroring the flow of a feature from idea to implementation. Users can be assigned to cards. Users and boards can be grouped into organizations.

Trello has limited support for tags, in the form of six colored labels that can be renamed. Cards accept comments, attachments, votes, due dates and checklists. Trello has an API.^[1] At the moment, the supported mobile app platforms are iPhone and Android.^[2] However, its website has been designed to be accessible in most mobile web browsers. An iPad application was released on March 12th, 2013.^[3]
