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.
With no page limit and 500 MB of space, you'll likely have more than enough space to build your site, and it even provides HTTPS/SSL encryption, meaning your visitor's information will be kept safe. Plus, you're able to integrate your site seamlessly with social media accounts. If you do decide to use Jimdo, beware of one thing: the builder prevents free websites from being indexed by search engines.
