Switching from WPO365: common questions
What is the best alternative to WPO365?
User Profile Builder is the closest match: it shares the same WordPress.org tags and has 40,000+ active installs with a 4.7 out of 5 rating.
Which WPO365 alternative has the most users?
Really Simple Security, with 3 million+ active installs reported by WordPress.org.
Which WPO365 alternative is rated highest?
Really Simple Security, rated 4.9 out of 5 by 8,863 reviewers. Only plugins with at least 50 reviews are counted.
Are these WPO365 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 WPO365 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 WPO365 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
User Profile Builder is the closest match to WPO365 by the data we track, and Really Simple Security has the widest reach with 3 million+ active installs. Check & Log Email 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.
