Cloudflare for SaaS
My SaaS, saas.com, allows users to pick a subdomain from a list of predefined domains (a.com, b.com, and dozens more). They can also bring their own domain. In other words:
FYI,
*.saas.comis only used for the SaaS—no UGC (user-generated content)—e.g. the root is for the homepage, while help.saas.com for knowledge base.a.com/b.comredirects to saas.com a.k.a the homepage. Someday they might have their own landing page instead of redirecting.*.a.comand*.b.comare for users. They can pick anything e.g.bla.b.comas long as it's available, not used by other users.- They can also bring their own domain, e.g.
sub.myco.com. - They can also choose nothing. Which means their UCG will be available from the root of a.com/b.com, e.g.
a.com/my-ucg. This is the default.
FYI,
saas.com, a.com and b.com are all managed in Cloudflare under one account (e.g. admin@saas.com).
