On the Sitefinity Marketplace there are 3 main sections - add-ons, themes & templates, and integrations.
The integrations section is just a listing of Sitefinity integrations with other solutions and applications that third-party companies offer.
The other two sections contain either free or paid extensions. All free extensions are validated and hosted by us. Those are marked with the "Sitefinity Validated" logo. Paid extensions are also validated prior to their publication on the marketplace however, they are hosted on the publisher's website, which also handles the purchasing.
Our long term goal is to have the best marketplace for CMS add-ons in therms of quality, content, and user experience.
