Any risks/pitfalls in transitioning over?
If you like super fancy js css stuff Gatsby rocks. However that is n rabbit hole from which you will not return. So ask yourself, should I be doing other things with my time than coding this website, if the answer is yes - you should probably use webflow and not spend two hours to center that div. I’m sure there is other cases where webflow is not the tool, if you selling stuff go with Shopify. Also I spent hours to get the Gatsby site on Netlify above 90 on google page speed test, with webflow it was 98 on the first go...
So from someone who would rather spend all his time solving complicated web app problems than shifting a flavour of our company page - go for webflow. And if it’s something you can solve with a reasonable webflow temple also do it.
