Switching from Custom HTML Block Extension: common questions

Which Custom HTML Block Extension alternative has the most users?
Hummingbird Performance, with 70,000+ active installs reported by WordPress.org.
Which Custom HTML Block Extension alternative is rated highest?
Lazy Blocks, rated 4.9 out of 5 by 80 reviewers. Only plugins with at least 50 reviews are counted.
Are these Custom HTML Block Extension alternatives free?
Every plugin listed here is free to install from WordPress.org. Where WordPress.org marks a plugin as commercial, the developer also sells a paid version or add-ons, and that is shown on each plugin.
How are alternatives chosen?
Automatically, from WordPress.org data: plugins that share a category top 10 with Custom HTML Block Extension score highest, then plugins that appear in the same WordPress.org rankings, then plugins with the same tags, weighted so rare tags count more than common ones. Plugins by the same author and plugins rated under 4.0 are left out.
How we choose these alternatives
Nothing on this page is picked by hand. Every day we walk the whole WordPress.org directory, then score every plugin against Custom HTML Block Extension on three signals: sharing a category top 10 counts most, then appearing in the same WordPress.org rankings, then carrying the same tags, with rare tags counting for more than common ones like "wordpress". Plugins by the same author are excluded, so an author's own add-ons cannot fill the list, and so is anything rated below 4.0 or with fewer than 100 active installs. The ten highest scores are what you see, in that order. Full methodology.
The bottom line
Lazy Blocks is the closest match to Custom HTML Block Extension by the data we track, and Hummingbird Performance has the widest reach with 70,000+ active installs. WindPress shipped the most recent release, on September 2, 2026. The list is rebuilt every day from WordPress.org, so a plugin that stops being maintained drops out on its own.
