@kc_kreative FBML has already been phased out. It was a hybrid programming language for Facebook and it is no longer available. Iframes is the process of how you get a tab to show in Facebook and is not a specific product. You can iframe pages or elements of a page into normal websites as well.
If you embed a youtube video using the youtube code it will be in the form of an iframe.
Woobox is simply a brand that provides different types of facebook tabs.
There are several free tab providers that have “iframes” in their name but just understand iframes is a process not a product, although some providers play on the name by including it in their brand or product name.
