Codecanyon is a marketplace by Envato, a company that runs several such marketplaces mostly focused on (web/graphic) design. Their main audience is designers and their source-code packages reflect that (as well as being created mostly by designers).
We on the other hand focus on professional code by professional developers. This is a generalization, but it’s very hard to find a good designer that is also a good developer.
We go to great lengths to ensure every package published on our service is held to industry standards. Each developer is screened using an invitation system. Each package is reviewed by one of our in-house developers for coding conventions, documentation and other necessities.
