This is fantastic all around. The visual design is perfect, it's fast, and within a minute of using it I discovered some new libraries which might be useful for my projects. It reminds me a bit of using Google search when it first launched and was less cluttered.

The clear layout makes it easy enough to mentally filter out common packages which appear in every search result, like gulp and grunt, but it might be a nice bonus to highlight packages that are "most uniquely" associated with the search term and not used by everyone else, or to cluster tools which are alternatives to each other together (e.g. putting gulp and grunt side by side on the same line).
