Are these CodeMirror Blocks alternatives free?

How are alternatives chosen?
Automatically, from WordPress.org data: plugins that share a category top 10 with CodeMirror Blocks 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 CodeMirror Blocks 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
HTML Editor Syntax Highlighter is the closest match to CodeMirror Blocks by the data we track, and HTML Editor Syntax Highlighter has the widest reach with 50,000+ active installs. aBlocks shipped the most recent release, on August 14, 2026. The list is rebuilt every day from WordPress.org, so a plugin that stops being maintained drops out on its own.
