# Custom hostnames

Last updated Aug 24, 2026|Copy as Markdown|[View as Markdown](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/cloudflare-for-platforms/cloudflare-for-saas/domain-support/index.md)|[Agent setup](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/agent-setup/)

Cloudflare for SaaS allows you, as a SaaS provider, to extend the benefits of Cloudflare products to custom domains by adding them to your zone as custom hostnames. We support adding hostnames that are a subdomain of your zone (for example, `sub.serviceprovider.com`) and vanity domains (for example, `customer.com`) to your SaaS zone.
