# Customer domains with SSL for SaaS

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

SaaS customers expect to use their own domains (for example, `app.theirdomain.com`) instead of a subdomain on your platform. Cloudflare SSL for SaaS provisions and renews SSL certificates automatically for every custom hostname, with no manual steps or customer action required.

## Solutions

### Cloudflare for Platforms

* **Custom domains** \- Customers bring their own domains and have them route to your platform with per-tenant configuration

### SSL for SaaS

Provision and manage SSL certificates for custom customer domains. [Learn more about SSL for SaaS](https://docs-durable-objects-instance-replaced-errors.previews.developers.cloudflare.com/cloudflare-for-platforms/cloudflare-for-saas/).

* **Automatic SSL** \- Certificates provisioned and renewed automatically for every customer domain with no manual steps
