Netlify support for saas company with thousands of custom domains

Hey @abdelhamid-attaby,
We can definitely support you white labeling our service as long as you’re on a Pro plan or higher. That said, we strongly recommend that you don’t proxy to us! If you proxy to us, you lose the benefit of our CDN and it will impact your end users’ site performance.

What we’d suggest instead is that you use our wildcard subdomains feature, which we can enable on a Pro account or higher. This means you could have a custom subdomain for each of your customers, i.e. customer1.yourstore.com, customer2.yourstore.com, etc. all pointing to the same underlying site. If you’re using Netlify DNS to host your DNS, we can take care of the SSL certificate for this configuration. Otherwise, you’ll need to bring your own wildcard SSL certificate.

A few caveats about this feature:

  • You can’t use domain aliases on a site with wildcard subdomains enabled, just the bare domain and subdomains under your primary domain. If you try to add a domain alias then it won’t work.
  • The primary custom domain for the site, if it is a “site.com+www.site.com” setting in our UI, must be www.site.com and NOT site.com!

Let us know if this helps or if we can answer any other questions!

Ah, and to your question about DDOS, we do not block IPs except in rare cases where there is an attack against our network, in which case we may temporarily block an IP in the course of mitigating the attack.
