Why White-Label SaaS Platforms Need Custom Domain Support
White-label SaaS products enable businesses to offer fully branded software solutions without building the platform themselves. Customers frequently request custom domains for SaaS to maintain a seamless professional identity and reinforce brand trust.
For developers building white-label instances or branded SaaS apps, supporting custom SaaS instances with proper domain mapping is essential. This allows user-facing applications and tenant applications to appear fully independent, while your platform instances handle the underlying infrastructure reliably.
Leveraging white-label domain infrastructure ensures that tenant domains are automatically verified, secured with SSL, and managed across all client instances without adding operational complexity.
Benefits of Using Hostgrid for White-Label SaaS Platforms
- API access to configure domains programmatically – Automate domain setup for client platform instances efficiently.
- Automatic SSL certificate provisioning and renewal at scale – Protect all branded SaaS apps with HTTPS instantly.
- Automatic DNS verification before enabling a domain – Guarantee domains are correctly pointed before activation.
- Centralized Management Dashboard – Monitor and manage all white-label instances and tenant domains from one interface.
How to Use Custom Domains with White-Label SaaS Platforms
Hostgrid supports both subdomain and path-based architectures, making it easy to map domains to your Whitelabel SaaS site.
For Subdomain architectures, eg client.yoursaas.com
With subdomain setups, each new client instance requires a dedicated domain mapping.
- Add your client’s platform instance as a new upstream, e.g.,
client.yoursaas.com. - Add your client’s domain in Hostgrid, e.g.,
clientdomain.comorapp.clientdomain.com. - Optionally provide the client’s email so Hostgrid can send DNS setup instructions.
- Client follows the DNS setup instructions.
- Hostgrid automatically verifies DNS and activates the domain with SSL.
For Path-Based Architectures, like yoursaas.com/client
Path-based configurations allow multiple white-label clients to share a single base URL while maintaining unique paths.
- Create a single Upstream for your base URL, e.g.,
yoursaas.com. - Add your client’s domain along with a unique path prefix, e.g.,
/client. - Optionally provide the client’s email so Hostgrid can send DNS setup instructions.
- Client follows the DNS setup instructions.
- Hostgrid automatically verifies DNS and activates the domain with SSL.
Hostgrid makes connecting custom domains easy. The API Starter plan starts at $20/month for 100 upstreams and domains — see pricing for more.
