Andre D. I would say that if you are using Figma, you'll see a lot of value in using Relume. If not, and also not using Webflow, you are probably leaving a lot of potential on the table but understand switching tools (or costs) is not feasible for all.
If using Figma, your WordPress development process is likely not to change much at all but we have no official exports for WordPress.
Another option would be to take a look at our HTML/Tailwind CSS exports which is a byproduct of our React export. Have heard of our customers using this as a jumping-off point for WordPress, but not clear as to the details of it.
