You don’t have to move your WordPress to Vercel. Your WordPress can remain in digitalocean, and the Frontity App will access to it through the REST API.
You can either deploy the Frontity App in Vercel following our docs, or you can also deploy it in digitalocean using Kubernetes as you would deploy any other React Application.
In both scenarios, you would have to point your domain to the Frontity server (Vercel or Digitalocean Kubernetes), so you will have to move your WordPress to a different domain or subdomain. This installation is what we call “direct to Frontity”.
