Divi is both a theme and a page builder, which is what makes it different from most items on this list. You install it once and you get the theme, the visual builder, and a library of ready-made layouts in the same package. The builder works on the front end, so you click on a heading, type the new text, and see the change straight away. There are hundreds of pre-made layouts for businesses, restaurants, portfolios, shops and blogs, and you can save your own sections and reuse them on other pages. The Theme Builder, included with Divi, lets you design headers, footers and post templates without a separate plugin. It also comes with split testing built in, so you can try two versions of a page and see which one gets more clicks or sign-ups. Divi is a good fit if you want one tool that covers design from top to bottom and you would rather not piece together a theme plus a separate builder plus extra plugins.
