Subdomain wildcards
Map every subdomain of your domain to a different page.
Wildcards are a Team feature. They let you bind *.yourapp.com to your Qubed account, then route each subdomain to a different page based on a mapping you control — perfect for multi-product launches, agencies, or per-customer microsites.
Set it up by adding a wildcard CNAME (*.yourapp.com → cname.qubed.xyz) plus the DNS-01 TXT record for SSL. Then in the dashboard's Domain routing panel, map each subdomain pattern ({slug}.yourapp.com) to a page in your account.
We support exact matches (alpha.yourapp.com → page A) and the special {slug} placeholder, which auto-routes any subdomain to a Qubed page with that slug. Unrouted subdomains fall through to a 404 page you can customize.
Cert issuance for wildcards uses DNS-01 validation, so the initial setup needs a single TXT record. Renewals are automatic and don't require any further action — we re-prove ownership every 60 days against the same TXT record.
