I think you should consider mentioning some of the options available for the open source version of WordPress (WordPress.org). The most notable option we have now I think is the page builder plugin Elementor from Pojo. The free version has tons of widgets one could use to build a responsive website for free without touching a line of code. I believe the space in WordPress.org is no longer for just for Developers. Anyone in the beginner stage can build sites on WordPress with much more flexibility than anything like WIX could ever offer since they are a closed platform. Mathew from LaunchParty has provided an amazing FREE course that will guide you how to build amazing sites with WordPress and Elementor. And he even provides you with amazing Elementor templates that you can use. Lastly, please note that not every thing that is meant to be sustainable is truly free. Last time I checked, in order to have a proper website with WIX, it was only free when you use their domain extension. If you ever wanted to remove WIX from the domain name, then you would have to pay for that. On the other hand, WordPress.org is open source, meaning free. But hosting is not, neither is your own domain name. There are many WordPress plugins that are worth paying for as well, including Elementor as well as others that will handle other important features such security.

However, if you aren’t a blogger, you may struggle to customize your site to your liking. This is where WordPress.com falls – it starts to feel limiting when you try to create anything other than a blog with its templates. It was the platform our users were least likely to recommend after testing, and also came out last for ease of use with a score of just 3.2/5.
