Spillo

Spillo is a powerful and fast Pinboard client for OS X. The program lets you browse and organize your bookmarks in an exquisite modern interface.

Spillo also makes creating a bookmark from anywhere on your Mac as convenient as possible. It allows you to create powerful collections by specifying a number of rules. You don’t need to limit yourself to Pinboard’s default organization - instead, you can create collections that just match your needs.
