Personalize your project by connecting a custom domain (e.g., yourname.com) or customizing your free .atoms.world subdomain. This guide walks you through editing your default address, connecting a domain you already own, or buying a new one.
Customize Your Free Subdomain
When you first publish a project, it is assigned a random subdomain (e.g., 1r945lo.atoms.world).
Open your project and click Publish in the top right corner.
In the publishing window, look for "Connected Domains" and click the Edit next to the current address.
Enter your desired name (e.g., alex) and click Update.
Your site is now live at your new subdomain (e.g.,
alex.atoms.world).
Connect a Domain You Already Own
If you have purchased a domain from a provider (like Alibaba Cloud, GoDaddy, or Namecheap), follow these steps to connect it.
Step 1: Start the Connection
Go to Settings and select the Domains tab from the sidebar.
Click on Connect Existing Domain.
Enter your full domain name (e.g.,
alex.com) in the text box and click Connect domain
Step 2: Configure DNS Records
The system will attempt to identify your provider. If automatic connection isn't supported, you must update your DNS records manually.
Select Manual Setup if prompted.
The system will display two records you need to add to your domain provider's settings: an A Record and a TXT Record.
A Record: Point this to the IP address shown (e.g.,
000.000.000.0).TXT Record: Add the specific verification string provided.
Step 3: Update Your Provider
Log in to your domain registrar.
Navigate to the DNS Settings or DNS Resolution section for your domain.
Add the records exactly as shown in the Atoms setup screen:
Type: A | Value: [IP Address from Step 2].
Type: TXT | Host:
_mgx_verify| Value: [Verification Code from Step 2].Important: The TXT record host differs for root domains and subdomains:
Root domain:(e.g.,
alex.com):_mgx_verifySubdomain (e.g.,
app.alex.com):_mgx_verify.appSubdomain (e.g.,
staging.alex.com):_mgx_verify.staging
Save your changes.
Step 4: Verify and Go Live
Return to the Atoms Settings page and click the button to confirm you have added the records.
Once configured, you will see a "You're all set!" message. Your domain status will change to Live.
Wait for the verification to complete.
Note: While DNS updates can take up to 48 hours to take effect globally, they usually complete much sooner.
1. Verify an A record. Use the `ping` command to check if your domain resolves to our gateway IP address (107.150.101.9).
# e.g., root domain of your domain name ping <yourdomainname.com> # e.g., app subdomain of your domain name ping <app.yourdomainname.com>
2. Verify TXT record.
# For root domain (yourdomainname.com) nslookup -type=TXT _mgx_verify.yourdomainname.com # For subdomain (app.yourdomainname.com) nslookup -type=TXT _mgx_verify.app.yourdomainname.com
Purchase a New Domain
If you do not yet own a domain, you can buy one directly through our settings.
Go to Settings > Domains.
Click Purchase New Domain.
Search for your desired name (e.g.,
hhhh-hhhh.com) to check availability and pricing.Add the domain to your cart and complete the checkout process via our partner, IONOS.
Once purchased, follow the prompts to connect it to your project.
Set a Primary Domain
If you have multiple domains connected (e.g., a free subdomain and a custom domain), you should set one as the Primary Domain. This ensures that visitors are always redirected to your preferred address.
In Settings > Domains, locate the domain you want to be the main address.
Click the Star icon or select Primary domain next to that domain.
This ensures that traffic to your other addresses (like
alex.atoms.world) will redirect to your custom domain (alex.com).
