What is free and self-hosted/desktop designer interface based on Bootstrap?

Good day
For prototyping the interface based on Bootstrap (3) need a tool which allows you roughly drag'n'drop-om to distribute the interface of existing components.
And that when attacked the layout it was just HTML, ie as close as possible to reality, and the result can be opened in the browser and show.

What is the solution? Online services are not suitable, because the creation will happen in offline Intranet network.

1 time for the license and pay all.
Himself use it - quite handy to quickly do a layout or sketch and test the interface/wireframe

In particular use to prototypicality interface and show the customer how I see the problem. - Rowena76 commented on June 8th 19 at 17:22
Once you pay and all:

Buy it once, own it forever
You can keep using the app forever after you purchase it.

But the updates only for a year.
Lifetime updates - for$ 60. (there are two tabs at the bottom of the page) - Miracl commented on June 8th 19 at 17:25
