Custom domains
Put your site on a domain you own. Attach it, add two DNS records, connect.
Your site is always live at {slug}.nertia.ai. On Particle or Wave you can put it on your own domain as well, and hosting comes with the plan. See Plans and billing.
Bring a domain you already own. nertia doesn't sell domains yet, so buy the name first at any registrar: Cloudflare, Porkbun, Namecheap, GoDaddy, wherever you like.
1. Open Domains
Open your site and pick Domains from the section tabs. The first row is your free address, {slug}.nertia.ai, and it stays live whatever you do below.
On Zero-Point this tab offers the move to Particle instead of a form.
2. Attach the domain
- Type the domain in the Domain field. Just the name, like
example.com. If you pastehttps://or a leadingwww., nertia trims it. - Leave Include www on. It sets up
www.example.comalongside the bare domain. - Press Attach domain.
The domain joins the list as Pending DNS. A domain already connected to another nertia site is refused.
3. Add the DNS records
The DNS records card shows what to add at your registrar, with a copy button on each value:
| Type | Name | Value |
|---|---|---|
| A | @ | 76.76.21.21 |
| CNAME | www | cname.vercel-dns.com |
Registrars label the fields differently. Name or Host is @ for the bare domain (some leave it blank), and www for the www record. Value or Points to is the value from the table, exactly as shown.
Records take anywhere from a few minutes to 24 hours to spread.
4. Connect
Back on Domains, press Check DNS. nertia checks the records with the host. When they are right the row turns Valid and the site is on your domain. If they have not spread yet, you see "DNS not verified yet", and the tab keeps checking on its own once a minute while you wait.
Connect domain skips the check and connects at once. Use it when you know the records are in and would rather not wait for the checker.
5. Launch on your domain
Once the site is published, Domains offers Launch on {domain}. The same button sits on the SEO tab. It points the canonical URL, the search metadata and the share cards at your domain, so links and previews name your domain instead of the free address. Publish the site first if the button says so.
Statuses
| Status | Meaning |
|---|---|
| Not configured | No domain attached |
| Pending DNS | Attached. Add the records, then check or connect |
| Valid | Connected and serving your site |
| Invalid configuration | The host sees the domain but the records are wrong |
When it doesn't work
| Problem | What to try |
|---|---|
| Check DNS says not verified | Compare the A and CNAME records at your registrar with the table, character for character, then wait a while and check again |
| www works but the bare domain doesn't | The A record is missing or points at the wrong address |
| The site loads but shows the old one | Your browser cached the old site. Try a private window |
| Certificate warning | The certificate follows DNS. Give it up to an hour after the records go in |
Changing plans
Your domain keeps working until 14 days after the last paid period ends. After that the site goes back to {slug}.nertia.ai. Nothing is deleted.
