BlockMeister

With BlockMeister creating custom block patterns becomes easy. The patterns can be designed just like you design a blog post or a page with the block editor. 
You can assign any (custom) category or keywords. By doing so, your patterns are categorized in a way that makes sense to your users and keywords make it easier to find a pattern. Your custom patterns will be available from the block patterns tab in the inserter panel.
Features
<ul>
<li>Visual design custom block patterns using the pattern builder</li>
<li>Or create a custom pattern from one or more selected blocks in the post editor</li>
<li>Import patterns made/shared by trusted Pro users [new in 3.0]</li>
<li>Assign your patterns to one or more categories</li>

<li>Set a viewport width to optimize the scaled width of the preview in the block inserter</li>
