Custom domains
A custom domain (like myname.dev) replaces the default URL your host gives you. Buy a domain from a registrar, add it in your hosting dashboard, then update the DNS records it tells you to. DNS changes can take a few minutes to a few hours to spread.
1. Buy a domain (Namecheap, Cloudflare, Porkbun...) 2. Vercel -> Project -> Settings -> Domains -> Add "myname.dev" 3. In your registrar's DNS settings add what Vercel shows, e.g.: Type Name Value A @ 76.76.21.21 CNAME www cname.vercel-dns.com 4. Wait for DNS to update. HTTPS is set up automatically.
