If you don't want to use the self-hosting package then there's a new button that lets you dowload the HTML with just one click: 
When you click this button a popup will appear with just the HTML of the form container. There's no HEAD, no BODY, no CSS, no JS.
Note that certain proprietary formstrap functions won't work and you'll have to implement a solution yourself:
- Form Pagination and initialisation
- Replicable Containers
- User Driven Events
- Custom Form Validation
- The "Other Please Specify" options on Select, Radio or Check input groups
But if all you want is the HTML, this is for you.
