I'd never use Jamstack.

Why?

Because Jamstack is used to build websites.

Any websites can be built 100x faster and cheaper using Wordpress + Elementor or Webflow.

If you're a freelancer, you can charge clients the same amount of money for less work while also keeping them more happy.

How will they be happier?

Because Jamstack requires a CDN, a build pipeline, and headless CMS. Too many moving parts = less robust infrastructure and higher maintenance costs.

Wordpress on a VPS is a single moving part.

When should you still use Jamstack anyway?

If you like cocktail parties with other developers, mentioning Jamstack might get you some attention.
