Architecture

According to a Fog Creek blog post in January 2012, the client was a thin web layer which downloads the main app, written in CoffeeScript and compiled to minified JavaScript, using Backbone.js,{{Cite web|url=http://backbonejs.org/#examples|title=Backbone.js|website=backbonejs.org}} HTML5 .pushState(), and the Mustache templating language.{{cite web|last=Kiefer|first=Brett|date=January 19, 2012|title=The Trello Tech Stack|url=http://blog.fogcreek.com/the-trello-tech-stack/|url-status=dead|archive-url=https://web.archive.org/web/20120121062341/http://blog.fogcreek.com/the-trello-tech-stack/|archive-date=January 21, 2012|access-date=January 8, 2013|website=fogcreek.com}} The server was built on top of MongoDB, Node.js and a modified version of Socket.io.
