Extendable

Block theme with one-click style variations, used in host onboarding

Overview

Extendable is a block theme published by Extendify, a company whose website markets its WordPress onboarding tools to hosting businesses for their customers.[10] It has been in the directory since June 2022 and reached the 200,000+ installation band, version 2.2.0 being published on 8 November 2026; it requires WordPress 6.6 and PHP 7.4.[4]

The directory description presents Extendable as a canvas for new sites with multiple style variations, from fresh to bold to minimal, applied with a single click.[4] It is a full block theme with Full Site Editing templates, block patterns, ecommerce tagging and RTL support.[4] Extendify’s site-creation tools are built around the theme, so it is most often met on new sites created through those tools.

Extendable has only four directory reviews, all positive, so its 100 out of 100 average says little.[4] There is no paid version of the theme itself. Site owners who did not receive it through a host may find the theme’s design system more useful if they also install Extendify’s plugin, while those who do not want an onboarding layer can treat it as a lightweight block theme with attractive defaults.
