Softr is best for building simple membership sites and websites that work well out-of-the box. You don't want to customize everything about how your site works, but you want it to work right away.

If you want more control over the design and more complexity, I'd recommend Webflow connected to Memberstack for a membership site, but that also comes with a higher learning curve.

If you're looking to build a web app with more complex logic I'd recommend checking out Bubble or Glide.

Webflow is a versatile tool, which makes it a great option for many types of projects.

For general websites, it's my top pick because it can be fully customized and has a built-in CMS to dynamically create pages (for example, you could create a page for every project in your portfolio automatically). Squarespace is the most similar for general websites - it's easier to use but less powerful.

For basic landing pages, tools like Umso and Carrd are easier to use but also less customizable.

For web apps, Webflow integrates with Memberstack to build paid membership apps. This is great for sites with premium hidden content such as No Code MBA.

For marketplaces, Webflow is great if you charge a subscription to access all content. If you need to handle payments directly to vendors, I'd suggest ShareTribe.

For e-commerce stores, Webflow is a great option if you want to prioritize design over more complex e-commerce functionality. In almost all other cases I'd suggest Shopify as it's easier to use and has a larger app ecosystem and community for e-commerce.

For web apps with more complex logic, I'd recommend Glide or Bubble.
