Page Builder by SiteOrigin
The best thing about Page Builder is that it’s free and in the WordPress repository. Always a plus. It has the essential basic modules, a good choice of page templates, and the user interface is decent. It’s also not shortcode driven, so if the plugin gets deactivated, it’s not going to make your content look weird. It doesn’t have as many options and customizations as some of our other contenders, and it’s certainly nothing fancy, but it’s a pretty reliable free choice, especially if you’re looking for a really simple page builder without too many distractions.
