Two years ago, there was no Wix vs. WordPress.
Wix.com Ltd. is an Israeli cloud-based web development platform that was first developed and popularized by the Israeli company also called Wix. It allows users to create HTML5 web sites and mobile sites through the use of online drag and drop tools.
Wix offers a basic website builder for free.
You cannot use a custom domain name for your site, so your site address will be: username.wix.com/sitename
To remove ads and get additional features, you’ll have to upgrade to one of the premium plans they offer.
Each Wix premium plan has different storage and bandwidth limitations. You can pay monthly or choose a yearly plan.
WordPress is a standalone software that you need to install (or have installed by a third party) on a web server. Only then do you get to use it as the software running your site.
Wix, on the other hand, is a tool/service that you sign up for. Once you’ve signed up, Wix allows you to build, and then manage, your website all within Wix.com. It takes care of the hosting and does all the technical heavy lifting.
Think of it this way: Wix vs. WordPress is much like Google Docs vs. MS Word.
