Custom Domain

Connect your own domain so your share links live on it instead of mdflow.cz.

Custom domain is a Pro feature. You can connect one domain.

Setting it up

  1. Go to Settings and add your domain.
  2. MDflow shows you the DNS records to add at your registrar.
  3. Add them, and MDflow checks the connection status while DNS propagates.

DNS propagation is not instant. The status check exists so you can tell the difference between "not working yet" and "misconfigured".

What changes

Once connected, the document and collection sharing panels offer two URLs:

  • The custom-domain URL — on your domain.
  • The permanent MDflow-domain URL — on mdflow.cz.

Both work. You choose which to hand out.

Private-share invitation emails prefer the custom-domain URL while your domain is connected, so recipients see a link on your domain rather than mdflow.cz.

Which URL should you use?

The naming is a hint: one is described as permanent.

  • Use the custom-domain URL for anything public-facing where the domain is part of the message — published documentation, a shared knowledge base, links you put on a website.
  • Use the MDflow-domain URL where longevity matters more than branding — a link in a signed contract, an archived reference, anything you cannot easily re-issue.

The reason is straightforward: your custom domain depends on your DNS and your registrar. If the domain lapses, changes hands, or its records are edited, links on it stop resolving. The MDflow-domain URL does not depend on any of that.

Interaction with sharing

A custom domain changes where a share link is served from, not who can read it. All the usual rules still apply:

  • Public links remain unlisted links — anyone with the URL can read them. See 01 Public Share Links.
  • Disabling sharing permanently invalidates the link on both domains at once.
  • Private email shares still require the invited person to sign in with the invited address. See 02 Private Sharing by Email.

If Pro lapses

Custom domain is a Pro feature. Plan for your links to fall back to the MDflow domain if the subscription ends — another reason to prefer the permanent URL wherever a link needs to survive unattended. See 04 Free and Pro Plans.
