How to connect a custom domain to your Airo AI Builder site
A custom domain is your own web address (like mybusinessdomain.com) instead of a temporary project URL. To connect one in Airo AI Builder, you buy a domain (or use one you already own), then connect it from the Domain tab or directly from the publish modal. When you buy through Airo AI Builder, DNS is configured automatically once you connect.
You built your site, chose a plan, and now you are ready to publish. But your web address still looks something like ni69faxn1l . c24 . airoapp . ai. That is not going on a business card, and it is not what you want customers to remember. A custom domain turns a live project into something people can find, share, and trust. You can now connect a custom domain directly while publishing — even on your first publish — from the publish modal.

How to buy and connect a custom domain
Custom domains in Airo AI Builder work in two steps: buy the domain first, then connect it to your project. If you purchase through Airo AI Builder, the domain is added to your GoDaddy account. From there, you connect it from the Domain tab (globe icon in the top toolbar).
The Domain tab is the recommended path for most customers. It is the most seamless way to purchase a domain and connect it to your project in one place, whether this is your first domain or you are adding another later.
Step-by-step instructions: Follow the Buy a domain tab in DNS for Airo AI Builder instructions in Help Center. That article covers buying from the Domain tab, connecting after checkout, and DNS setup, including automatic configuration when you buy through Airo AI Builder.

Connect a domain you already own
You can connect a domain that is already in your GoDaddy account, or one registered with another provider. Open the Domain tab (globe icon) to get started.
Step-by-step instructions:
- GoDaddy domain: Follow the Help Center instructions.
- Non-GoDaddy domain: Follow the non-GoDaddy domain tab in the same article. The Domain tab shows the DNS records to enter in your provider's dashboard. Changes can take up to 48 hours to take effect.
Frequently asked questions
What is a custom domain?
A custom domain is a web address you choose and own (like mybusiness.com) that replaces the temporary URL Airo AI Builder assigns when you publish. It is what you put on business cards, in email signatures, and in search results.
How do I connect a custom domain to a site built with Airo AI Builder?
Open the Domain tab (globe icon in the toolbar). Click Buy a New Domain to purchase one, or type in a domain you already own. If you buy through Airo AI Builder, the connection is set up automatically.
Do I need to configure anything manually?
No manual configuration is needed when you buy through Airo AI Builder. If you connect a domain from another provider, you will update a few settings in that provider's dashboard to point the domain to your site.
How much does a domain cost?
Pricing depends on the extension (.com, .net, etc.) and availability. Airo AI Builder shows current pricing when you search. Promotional first-year pricing varies by domain; renewal pricing is typically higher than the introductory rate. Check pricing at checkout before you purchase.
How long until my custom domain works?
If you buy and connect through Airo AI Builder, your domain can go live shortly after connection. If you connect a domain from another provider, allow up to 48 hours for DNS changes to take effect.
Can I connect more than one domain to the same project?
Yes. Add multiple custom domains under the Custom Domain section in the Domain tab.
Where does my domain live after I buy it?
In your GoDaddy account. Manage billing, renewals, and settings from the GoDaddy Domains dashboard at any time.
Can I connect a custom domain on the free plan?
No. Publishing your site and connecting a custom domain require a paid plan. The free plan gives you 50 AI credits to build and preview your project. When you are ready to go live with your own domain, upgrade to a paid plan first.
Can I use a domain I bought somewhere else?
Yes. Enter your domain in the Custom Domain section and follow the instructions Airo AI Builder provides.
