Why E-commerce Store Builders and Marketplaces Need Custom Domain Support
E-commerce platforms and marketplaces allow merchants to sell products online without managing hosting, payment, or inventory infrastructure. However, store owners often want to connect custom domains for stores so their merchant storefronts appear on branded URLs rather than platform subdomains.
For developers building store builders or e-commerce marketplaces, supporting user storefronts with domain mapping is critical for branding, trust, and SEO. By enabling custom domain routing, your online stores can feel like fully independent websites while still being powered by your platform instance.
Integrating white-label domain infrastructure ensures that your tenant domains work reliably, with automated SSL provisioning and DNS verification, without the complexity of managing cloud infrastructure.

How to Use Custom Domains with E-commerce Store Builders
- Add your user’s site as a new upstream, e.g.,
user.yourstorebuilder.com. - Add your user’s domain in Hostgrid, e.g.,
userdomain.comorshop.userdomain.com. - Optionally provide the user’s email so Hostgrid can send DNS setup instructions.
- User follows the DNS setup instructions.
- Hostgrid automatically verifies the 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.
