Cloudflare partners with Render to provide Render customers’ web services and static sites with Cloudflare’s performance and security benefits.

If you use Render and also have a Cloudflare plan, you can use your own Cloudflare zone to proxy web traffic to your zone first, then Render's (the SaaS Provider) zone second. This configuration option is called O2O.

Benefits

<Render file="provider-guide-benefits" product="cloudflare-for-platforms" params={{ providerName: "Render", providerAssets: "services" }} />

How it works

For additional detail about how traffic routes when O2O is enabled, refer to How O2O works.

Enable

Render customers can enable O2O on any Cloudflare zone plan.

To enable O2O for a specific hostname within a Cloudflare zone, create a Proxied CNAME DNS record with your Render site name as the target. Render's domain addition setup will walk you through other validation steps.

Type	Name	Target	Proxy status
CNAME	<YOUR_HOSTNAME>	<RENDER_SUBDOMAIN> (for example, example.onrender.com)	Proxied

:::note

For more details about Render setup, refer to their documentation.

If you cannot activate your domain using proxied DNS records, reach out to your Cloudflare account team or your Render support team.

:::

Additional requirements for wildcard subdomains

With O2O enabled, adding a wildcard subdomain to a Render service requires that the corresponding root domain is also routed to Render. If the root domain is routed elsewhere, wildcard routing will fail.

If your root domain needs to route somewhere besides Render, add individual subdomains to your Render service instead of a wildcard.

Product compatibility

Zone hold

Additional support

Resolving SSL errors

If you encounter SSL errors, check if you have a CAA record.

If you have a CAA record, verify that it permits SSL certificates to be issued by Google Trust Services (pki.goog).

For more details, refer to CAA records.
