As there’s currently no native OS X app supporting Feedly yet1, the official blog of Feedly provided a workaround, which utilized Fluid, “an app that can turn any web page into desktop app”, to create a standalone Feedly app. They even provided an original Feedly icon.
Fluid is free for use. If you are willing to pay an extra fee of $4.99,2 you can unlock a set of premium features including “the ability to enter full screen, options to have separate cookies storage (which mean you can run multiple of Feedly accounts at once), use Userscripts and Userstyles, and pinning the app into menu bar”. »
