Deployment
A whole host of ways to deploy exist. Vercel, Netlify, Railway, a VPS, a server at home...
No matter the method, all are good if they meet your needs.
Personally, I advise you to use a VPS at Contabo/Netcup/Ovh etc.
And go for a clean installation of Coolify and get a domain name from ovh/cloudflare in the process.
