Multi-tenant custom domain biolink: brand authority
Allow every creator, brand, and corporate client to display their bio link under their own domain name (e.g., links.clientbrand.com) via multi-tenant CNAME routing.
How CNAME custom domain mapping works in Bibiolink
In a typical hosted SaaS, enabling custom domains requires manual administrative intervention or expensive enterprise plans.
Bibiolink contains a native multi-tenant routing engine:
- The user inputs their desired domain or subdomain into their settings.
- The user creates a DNS CNAME record pointing to your server's hostname.
- Bibiolink resolves incoming host headers to verify and match the registered tenant account.
- Once configured, incoming HTTP/HTTPS requests with that `Host` header immediately serve the user's bio profile under their brand.
Subdomains, root domains, and reverse proxy routing
Bibiolink supports three levels of domain routing:
- Path Routing: Default fallback (`yourdomain.com/username`).
- Wildcard Subdomains: Instant deployment (`username.yourdomain.com`).
- Custom Third-Party Domains: External CNAME (`links.clientbrand.com`).
| Routing Dimension | Specification |
|---|---|
| CNAME Verification | Automated In-Script DNS Lookup |
| SSL Protocol | Automatic In-Script SSL Provisioning |
| Domain Isolation | Strict Multi-Tenant Database Mapping |
| Root Domain Support | Supported via ALIAS / ANAME or Cloudflare CNAME flattening |

Common questions about multi-tenant custom domains
How do subscribers point their custom domain to my platform?
Subscribers add a standard CNAME record in their DNS management dashboard (e.g. at GoDaddy, Namecheap, or Cloudflare) pointing `links.theirbrand.com` to your platform's primary domain. Bibiolink automatically detects the incoming CNAME host and routes visitors to that subscriber's bio link.
How does SSL certificate configuration work for custom domains?
Bibiolink handles SSL automatically. When a subscriber configures a custom domain, the script performs automated DNS verification and provisions SSL certificates automatically, ensuring seamless HTTPS connectivity.
Can subscribers also use system subdomains?
Yes. In addition to custom external domains, every subscriber can be assigned an instantaneous system subdomain (e.g. `creator.yourdomain.com`) as well as standard path routing (`yourdomain.com/creator`).
