Custom Block Builder – Lazy Blocks

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Share of active installs on each version of this plugin. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price.

   We have made some advanced blocks mixed with custom PHP functionality and this plugin has saved us a tremendous amount of time. Highly recommend for devs and non devs. This topic was modified 2 years, 4 months ago by Steven Ayers.

   The plugin is great, it helped and speeded up the process of developing custom blocks with pre-defined options for authors. The options to create any block with any function are endless. I ran into an issue once and the personal support by the developer solved the problem in few days. I can really recommend the plugin. I purchased the pro version and it is going be part of many future pages we develop as an agency. I can recommend the plugin to everyone who want’s to transition to full site editing and Gutenberg, but doesn’t want to completely forget all the WordPress development we learned and loved the last 20 years.
