Sawyer from EasyPost here. Yes, we're generally upstream of Shippo - we power a bunch of their competitors in the app / shipping UI space. We focus more on developer APIs and all of the tools and performance considerations that come with that.

Our UI developers are focused mainly on analytics for the platform - we're happy to leave the click n' ship piece to Shipstation, ShipRush, Shippo, etc.
