<p>With the Controlled Content Block you can create a Content section where you have control over which blocks are allowed. Use this block if you have a section where you only want paragraphs. The block also features a filter to control who can change which type of blocks are available. The possible allowed core blocks are paragraphs, lists, headings, and images. If you would like to add or remove blocks from these choices there is a filter for that too.</p>
<p>The block also features a filter to remove the meta box for selecting allowed blocks for certain users.</p>

Advanced Bootstrap Blocks

... and that's not saying much because the others were broken or terrible. Even still, this one is on the right track, and I'm happy to see that at least somebody is getting it right. Thanks for your hard work!

So far the best bootstrap block plugin

This is really well done, it does lack some features to become perfect, and has some issues with the editor (columns chaos if multiple classes are set) but it works perfectly. By far the fastest way to get Bootstrap into Gutenberg : THUMBS UP

Very usable !

Build responsive Bootstrap 4 layouts inside the Gutenberg editor.
