Katalog is an app for creating catalogs and items that belong in them. It is designed to scale, with performance in mind at each step and request. For example, the database is never queried from views, avoiding the n+1 query problem. Further, users who choose to register via Google OAuth can create, edit and delete catalgos and items.
Katalog is live on Heroku.
