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 Reduce Unused CSS Solution with Critical CSS For WP 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
Hummingbird Performance is the closest match to Reduce Unused CSS Solution with Critical CSS For WP by the data we track, and Jetpack Boost has the widest reach with 200,000+ active installs.
