Loops & Logic is a code-centric templating toolkit that includes support for Advanced Custom Fields. You can use Loops & Logic’s like a theme builder to create single and archive content templates. It also comes with a Gutenberg block, Elementor widget, and Beaver Builder module so that you can place Loops & Logic templates pretty much anywhere. Some people may want to build their entire site with it, but many people will use it to create custom views of site content to fill in the gaps of Gutenberg or their page builder.
Tangible, the agency behind Loops & Logic, created this tool for their own use, so it does not require commercial success in order for it to be maintained and updated.
