Chat URL

Just use the "Add my domain" feature on the share page and set up your CNAMES. I think you could even do it for a root domain.

Not sure if that option is only available in the cloud version though...

yes is possible and you need only to add your domain and manage the dns for your domain.
You only have to add a A Record

Type A

Name @

Value 76.76.21.21

in case of root domain you need to manage the A record and not the Cname but the action is similar 🙂

Hello, in the latest versions I see that the Custom Domain option in the "Share" section no longer appears, and I would like to know why?

I would like to know if I need to do any additional configuration to be able to use custom domains for different chats.

Previously this option appeared, but I had never used it and now I want to use it to customize my customers' chats based on my customer's domain.

Like this:

Only possible if you host it on Vercel
