Custom domains

Connect a domain you own — Stripe Hosting, DNS records, Connect domain.

Publish on https://yourdomain.com in addition to your free {slug}.nertia.ai subdomain.

Hosting: $20/mo per site, charged when you start domain checkout from the dashboard. You must own the domain already — nertia does not sell domains in-app yet (buy at GoDaddy, Namecheap, Cloudflare, Porkbun, etc.).

Step 1 — Open Domains

Open your site → section menu → Domains (/dashboard/{slug}?tab=domains).
Your free subdomain is always listed: {slug}.nertia.ai.

Step 2 — Start Hosting checkout

Enter the domain you own (apex only — example.com, not https://).
Click Continue to payment.
Complete Stripe checkout ($20/mo Hosting for this site).
Return to Domains with ?tab=domains&upgraded=1.

Status moves to Pending DNS — payment received; DNS not verified yet.

Step 3 — Add DNS records

Copy the records from the DNS records table in the Domains tab and add them at your registrar:

Type	Name	Value
A	`@` (apex)	`76.76.21.21`
CNAME	`www`	`cname.vercel-dns.com`

Registrar UIs label fields differently:

Name / Host: @ or leave blank for apex; www for www
Value / Points to: paste exactly from the table

DNS propagation can take minutes to 48 hours.

Step 4 — Connect domain

After records are saved at the registrar, return to Domains.
Click Connect domain.
Status becomes Valid (active). The site record stores customDomain and hostingTier: paid.

Middleware routes traffic for your hostname to the correct site.

Step 5 — Publish on your domain

In the Editor publish menu:

Action	Host
Publish to staging	`{slug}.nertia.ai` (always available)
Publish live	Your custom domain (after Connect domain)

If DNS is still pending, the menu links you back to Domains to finish setup.

Launch on {domain} (when offered) runs the launch pipeline — canonical URL, SEO, and share cards pointed at your custom host.

Status reference

Status	Meaning
Not configured	No domain checkout started
Awaiting payment	Checkout started, not completed
Pending DNS	Paid — add records, then Connect
Valid	Connected and routing

Troubleshooting

Problem	What to try
Connect fails	Confirm apex A and www CNAME match the table exactly
Site not loading after Connect	Wait for DNS propagation; try incognito after 30+ minutes
www works but apex doesn’t	Apex A record missing or wrong IP
SSL certificate pending	Often follows DNS — allow up to an hour

nertia maps your domain in Firebase after Connect domain. TLS and edge routing are handled by the hosting platform.

What is not included

Domain registration in nertia — buy elsewhere first
Email on your domain — configure at registrar or email provider separately
Transferring a paid Hosting subscription to another slug — contact support
