Can my users setup custom DNS for their page?

[albttx]

I’m working on a SaaS, and i want all my users to be able to setup

sub.myclientwebsite.com

I’ve tried:

• Setup Vercel wildcard *.myapp.com

So going to myclientwebsite.myapp.com (vercel deployed) show the correct page.

But putting a CNAME on sub.myclientwebsite.com to myclientwebsite.myapp.com isn’t working and is going 404.

I understand that Vercel proxy don’t “know” how to handle a request from myclientwebsite.myapp.com.

Does anyone have an idea ? I was thinking maybe using cloudflare ?!

I see the solutions to use vercel API to dynamically add in the DNS / Router list all my clients redirections. But i might get limitions in the future…

Any help is appreciated
