Zendesk for example puts their customer dashboards on a direct subdomain of their own main domain. They allow people to use their own domains as well. To use your own domain you have to make it a CNAME for the subdomain that they gave you. https://support.zendesk.com/hc/en-us/articles/4408838571930-Host-mapping-Changing-the-URL-of-your-help-center https://support.zendesk.com/hc/en-us/articles/4408838571930-... I think it’s better to do like GitHub and Shopify and many others do. Have a separate domain at least that customer pages are made subdomains of. GitHub uses GitHub.com as their own domain, and they use GitHub.io as the pages domain with subdomains for users. Shopify uses Shopify.com for their own site and myshopify.com for customer subdomains. The main advantages of using a separate domain for customers include: - You don’t have as many pre-existing or future subdomains that you want for yourself. (You still need to filter so that people don’t use offensive words or misleading words etc.) - You can have that domain added to the Public Suffix List, which avoids some potential problems you might otherwise run into https://publicsuffix.org/ https://publicsuffix.org/
