If you already have a domain purchased from a provider, you can add as many subdomains as you like with that provider for free. You just need to add the DNS records on the provider side. Each custom subdomain still counts towards your custom domain plan limit in Softr.
Custom domain and extra custom domain slots depend on the subscription plan. See plan comparison.

2. Update the DNS

Access your domain's DNS settings in your domain registrar's or DNS host's dashboard.

Every DNS host has its own way of updating DNS settings. Please, read the help documentation of your DNS host if you are not familiar with it yet. Also, check out our FAQ on domain setup.

Add an A record

You will need to create an A record as follows:

  • For the A record, set the host to the subdomain part of the URL ("my" in our example);
  • Input the IP address we've provided for you: “”

To verify that your DNS settings are correct, and that your subdomain is correctly pointing to Softr, check the status of your domain name in your DNS settings.

DNS changes may take a few minutes for your A name records to propagate everywhere. If you still run into any issues with your domain verification, reach out to your DNS provider to make sure the records are set correctly.

3. Publish your application to your custom subdomain

Now, if you click on the Publish button within your Softr studio's top navigation bar, you should see your custom subdomain in the menu that opens. Click the Publish button, and you are almost done.

It may take up to 48 hours before changes are successfully made from your DNS host, so that you are able to open your application with your subdomain.

When the DNS records in your Settings => Custom Domain page show up as Connected in green color, your subdomain is functional.

If your subdomain is not working correctly after 48 hours, contact your domain provider’s support. If your DNS settings are correct and you are still experiencing issues with your published application, contact us and we'll assist.
