Packery: The Bin-Packing Layout Library

Packery is a JavaScript layout library that uses a bin-packing algorithm. This is a fancy way of saying “it fills empty gaps.” Packery layouts can be intelligently ordered or organically wild. Elements can be stamped in place, fit in an ideal spot, or dragged around.

For non-commercial, personal, or open source projects and applications, you may use Packery under the terms of the MIT License. You may use Packery for free. Packery may be used in commercial projects and applications, but it requires a one-time purchase of a commercial license though.
