Connect your own domain

Every project is live from the moment it exists, at your-project.coagentic.site. Connecting your own domain changes the address visitors see — same site, your name on it, with HTTPS set up for you.

Or don't do any of this yourself. Ask your assistant: “put shop.example.com on the bakery site”. It attaches the domain, reads you the exact records to paste into your DNS provider, and you can ask it “is it ready yet?” instead of watching a screen.

What you need

A domain you ownBought from any registrar — Cloudflare, GoDaddy, Namecheap, Google Domains, anywhere.

Access to its DNS settingsThe place you can add records. Usually your registrar; sometimes a separate DNS host.

A paid planCustom domains are part of Starter and above. Your site stays live either way — this only changes the address.

Step by step

1Add the domain

Open the project, go to Site → Domain, and type the address the way visitors will: example.com or shop.example.com. Pasting a full URL is fine — it is trimmed for you.

2Publish the two records

The screen shows exactly what to add, with the values ready to copy. There are two, and both are needed:

Type	Name	What it does
TXT	_coagentic-verify.your-domain	Proves the domain is yours. Without it, anyone could claim any name.
A	your-domain	Sends visitors to your site.

Copy the values from the Domain screen rather than from here — the TXT value is unique to your domain.

3Check

Press Check DNS. If the records are visible, the domain goes live and a certificate is issued automatically — HTTPS included, nothing to buy or renew.

If it says the records are not there yet, that is normal: DNS changes take anywhere from a few minutes to an hour to travel. Nothing is lost — check again later.

Common snags

It has been an hour and the TXT record still is not found.›

Check the record's name. Most DNS providers add your domain automatically, so you type _coagentic-verify and they store _coagentic-verify.example.com. If you typed the full name in a provider that does this, you now have _coagentic-verify.example.com.example.com. Also check the value has no quotes added around it.

The domain resolves but the site does not load.›

Your A record probably points somewhere else — a parking page from your registrar is the usual culprit. Remove any existing A or CNAME record for the same name, then check again.

HTTPS is broken after DNS verified.›

Certificate issuance takes another minute or two. If it is still broken after half an hour, check for a CAA record blocking Let's Encrypt: dig CAA your-domain. A CAA naming a different authority is the reason.

Can I use a www address?›

Yes — add www.example.com as its own domain. Many people add both the apex and the www version.

What happens if my plan ends?›

The domain keeps working for seven more days, then visitors are redirected to your platform address, which stays live for free. The site never goes dark. More on plans.

Can I remove a domain later?›

Any time, from the same screen or by asking your assistant. The site stays live at its platform address.

Email & sending domain

Send from your own domain too — a separate set of records, same idea.
