I switched a service from Ember to Vercel and got rendering improvement

Worked for the last week learning NextJS and rebuilding an old project in Vercel. Cannot speak more highly of the product and the framework. I don't often write frontend code, so maybe I have been living in the past, but I would recommend NextJS and Vercel to anyone building a product with SEO requirements.
