This feature is only available on the Business plan.
To set this up, you need to complete all steps below:
Decide on a subdomain to use (e.g. portal.yourdomain.com). Naked domains (e.g. yourdomain.com) are not supported.
Add DNS record. Your subdomain needs to point to the information below. Your domain registrar (where you have registered your domain) should have instructions on how to set this up, since this is a setting you will need to make on their platform. Some registrars (Squarespace for example) might only require the first part of the subdomain (portal instead of portal.yourdomain.com) to be entered for the DNS record, but others will require the full subdomain here so please double check exactly what you need to enter in the corresponding field for your registrar!
Go to Workspace Settings and select the correct workspace on the left
Locate the Custom Domain section
Enter your Custom domain (should not include http, www or other prefix, see supported domains below) and click Add custom domain
A table will now appear with TXT DNS records you need to add to your DNS configuration as well. If the table doesn't appear right away, please hit the refresh button.
Once these steps are complete, the updates will take effect within a few hours.
To test if the custom domain is already working, you need to:
Copy the link of your form or portal.
Replace the "web.miniextensions.com" with your custom domain (eg. portal.domain.com/xyz)
Load the new URL in your web browser.

Supported Domains
This feature only supports subdomains (e.g. portal.domain.com). It doesn't support naked domains (e.g. domain.com).
Supported Plans
It’s only possible to set up a custom domain on the Business plan.
Supported Extensions
This feature only affects the customer-facing interfaces like form and portal. The extensions setting page will still be using web.miniextensions.com.
Will the existing URLs of my forms and portals be affected?
No, the old URLs will still be functional.
Can I set different domains for different forms/portals within the same workspace?
No. You can configure only one custom domain per workspace. If you need to set up multiple custom domains, you would need to create additional miniExtensions workspaces, each with its own custom domain configuration.
Captcha is getting an error. Is this not supported in the custom domain?
This is compatible with the custom domain. If you require this feature, please contact us, and we will enable it for you.
💡Tip
You can also embed the extension on your site as an alternative.
