PlayBackk is a Platform where you can host Your Podcast in the form of "Shows" and for Free without any RSS Feed and your content shows directly in the Built-In PlayBackk Feed. With the Creation of one Account, You can host as many shows as possible.
Most podcast host will abstract away the RSS part. But the RSS part is actually a feature, not a bug. I don't know why anyone would like to not use it.
