Advanced Download

If you want to, you can build your personalized copy of MooTools Core. You might want to leave out components you don't need such as Effects or Requests, or you might want a personalized build for non-browser environments. Either way, this full version contains all the components listed in the core builder.

Edge Build

If you want to get involved in testing and development, you can download the edge version of the MooTools core. This version is built after each commit from our git repository. Always include MooTools.build if you wish to open up a ticket.

You can also download an edge build of MooTools More. This file includes all plugins of MooTools More, which is usually not a good idea, so only use it for testing purposes.
