Custom Domains for Next.js: The Cloudflare + Vercel Setup That Works in 2026

You shipped a Next.js app to Vercel. It's live at your-project-xxx.vercel.app\. Everything works, but the URL looks like a throwaway demo.

Getting a real domain is a 30-minute task, but it's easy to make mistakes that cost you SSL certificates, SEO, or deliverability.

Here's the exact flow I used to move my template business from a vercel.app URL to my own domain. Production-tested, 2026-current.

The Stack

• Registrar: Cloudflare Registrar (at-cost pricing)
• DNS: Cloudflare DNS (free, fastest propagation)
• Hosting: Vercel
• Email Routing: Cloudflare Email Routing (free receiving)
• Email Sending: Loops.so

Zero monthly cost except the domain itself (~$12/year for .dev).

Step 1: Buy the Domain on Cloudflare

Use Cloudflare Registrar, not Namecheap or GoDaddy. Prices are wholesale, WHOIS privacy is free, and DNS is managed in the same dashboard.

1. dash.cloudflare.com → Domain Registration → Register Domain
2. Search your domain
3. 2 years with auto-renew ON
4. Pay. Domain is yours in ~60 seconds

Step 2: Add the Domain to Vercel

1. Open your Vercel project → Settings → Domains
2. Click Add Domain
3. Enter your domain
4. Uncheck "Redirect to www" — apex as canonical is cleaner in 2026
5. Save

Vercel shows Invalid Configuration. Expected.

Step 3: Get DNS Records

Click Edit in Vercel → Manual setup. Vercel shows:

\
Type: CNAME
Name: @
Value: <project-hash>.vercel-dns-xxx.com
\\

Vercel is migrating from the old A record (76.76.21.21) to CNAME-based records.

Step 4: Add to Cloudflare DNS

Cloudflare → your domain → DNS → Records → Add record:

\
Type: CNAME
Name: @
Target: <Vercel-provided value>
Proxy: DNS only (gray cloud) ← CRITICAL
TTL: Auto
\\

Why DNS only matters: Cloudflare proxy ON intercepts HTTPS, so Vercel can't issue SSL. Keep it gray.

Step 5: Wait for Verification

Vercel auto-detects propagation in 2-10 minutes. Green check = done.

The Apex CNAME Gotcha

DNS spec (RFC 1912) doesn't allow CNAMEs on apex. Cloudflare solves this with CNAME Flattening — internally resolves to IP, returns A record. You don't do anything special.

AWS Route 53 calls this "ALIAS". Google Cloud DNS has similar. If your DNS provider doesn't support this, use A record with Vercel's IP instead.
