You are correct regarding CMS. Same story with e-commerce and other things. In fact fundamentally the architecture is built around the idea of not having those things built-in but rather providing APIs for others to create integrations with any data source: CMSs, Databases, E-commerce etc.

Webflow and others with built-in CMS have a massive amount of problems, because there is no one CMS that fits all.

Even harder is e-commerce.

So yeah, we are not going to compete on that because we are not building any of it, but instead focusing on architecture to support integrations.

Webflow CMS is expensive, I can see a small business starting out with Webflow and getting locked in. I can't see a more mature business doing this, as they'd want hosting flexibility. WordPress page builders don't have any hosting lock-in.

It is expensive, but it's more expensive to hire a programmer to do similar features on a website.

Wordpress is more flexible but it just lack the product polish for consumer or even programmers like myself.

If I am building a new product, I'm not going to also try to build a website.
