Trello is a web-based project management application originally made by Fog Creek Software in 2011, that spun out to be its own company in 2014.
It operates a freemium business model, as well as being cross-subsidized by other Fog Creek Software products. A basic service is provided free of charge, although a Business Class paid-for service was launched in 2013.
“Trello is a project management tool that does that the collaboration is simple and, I would dare to say, even enterteining. The reality is that it serves for almost quite, already you are organizing projects in the work, tasks of the home, trips or any another thing.“
It supports iPhone, Android and Windows 8 mobile platforms, however, its website has been designed to be accessible in most mobile web browsers. An iPad application was released on March 12, 2013. It added support for an unlimited number of tags, in the form of colored labels that can be renamed and new ones created, starting November 21, 2014. Cards accept comments, attachments, votes, due dates and checklists. Trello has an API.
Users may organize projects through the utilization of boards, lists and cards, which form a bespoke data hierarchy that facilitates effective management of projects, jobs and tasks.
In 2015, Trello launched third-party integrations with tools such as Slack, GitHub and Salesforce for its paying users. In 2016, Trello opened this platform to additional developers with the launch of its “Power-Ups Platform” for developers wanting to integrate their services with Trello.
Trello uses the kanban paradigm for managing projects, originally 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.
