Wildcard subdomains, tenant custom domains & automatic SSL
Building a product where your customers get their own hostnames? One Phoenix app can now serve unlimited tenant hostnames, with automatic HTTPS.
Wildcard subdomains
Give every tenant their own subdomain, like moonstone.potionshop.xyz and nightshade.potionshop.xyz. A single wildcard certificate covers all of them, so new tenants work instantly. Any DNS provider works.
Tenant custom domains
Your tenants can also bring their own domain, like example.com, with SSL handled automatically. Your app stays in control of which domains get approved.
