Another big name when it comes to eCommerce platforms after Shopify is BigComerce. It is a hosted e-commerce solution that allows the users to set up their own online store and sell their stuff. It is flexible allowing anyone from beginners to experts to use the services and create the ideal platform. Compared to WordPress however, it is not ideal for other types of sites.
While there are modules and themes that extend the features and looks, novices find it a bit difficult to create a detailed site with it. However, the complexity of Drupal is appropriate for handling huge amounts of data. This makes it ideal for larger corporate and enterprise websites. Just like in WordPress and Joomla, Drupal also allows various extensions in the form of modules. But the difference here is, unlike WordPress users need to leave the system and manually search for the modules before installing them.
If you’re knowledgeable about site building and e-commerce, you’ll find solutions on this list that give you better extension possibilities, more overall features, and the freedom to potentially do anything you want with your online store (since you’d be hosting it on your own server). That said, if you’re just getting into selling things online and want to do everything yourself, Shopify can often be a great place to start for new businesses and less technically-savvy folk!
WHICH IS BETTER: Squarespace vs. Wordpress
I agree with you that Pulse CMS offers an interesting way to go, without databases. Before moving all my sites to WP over the past two years, I had always felt reluctant to use databases: but testing WP had convinced me to go ahead. Although I do not use it at this point (I played a little bit with previous versions), I bought a Pulse CMS license, if only in order to support that interesting project. I do not rule out using it for a site some day, at least experimentally.
