Hi @kumi,
Apologies for the late reply.
Please note that in Softr, custom domains and subdomains are considered equal, meaning that in a given plan, your app can only have one custom domain or subdomain pointing to one of your apps. Please note that subdirectories are not supported in Softr. If you have, for example, two apps but your plan allows only one custom domain or subdomain, you will need to purchase an extra slot for that additional custom domain or subdomain regardless the formatting you chose for it. The extra custom domain costs $15 per month or $156 annually.
