Sitecore Embeddable Forms
Sitecore Embeddable Forms Framework (EFF) allow forms to be displayed on any website page, including websites that are not Sitecore applications. They are isolated and unobtrusive; hence they cannot hurt any other functionality or style of the page where they are embedded.
We have discovered an issue with some of our Developer downloads. Out of an abundance of caution we have temporarily disabled download ability while we address this issue. We hope to have access available as soon as possible; in the meantime please work with your customer support / account executive representative to get the access you need.
