# Custom domains

> Custom domains let a published Mythos site live on your own address instead of your-name.r21.dev. This capability is coming soon and not yet available.

A custom domain points your own address — like `yourbrand.com` — at a site you've published with Mythos,
instead of the default `your-name.r21.dev` subdomain.

This page describes the capability and where it stands today.

<Note>**Status: coming soon.** Custom domains are not available yet. In the Publish panel you'll see an
**Add custom domain** option marked **Soon** — it's a placeholder for this feature, not a working flow.
Published sites currently live on `*.r21.dev`.</Note>

## What you can do today

Every published site gets a `your-name.r21.dev` address that you fully control:

* **Choose the subdomain** — the `your-name` part is yours to pick on the publish URL step.
* **Rename it anytime** — change the subdomain whenever you like; the new address is live within seconds.

For now, that subdomain is the public address for your site. See [Publish your site](/publishing/publish)
for how to set and change it.

## When the feature ships

A custom domain will let you serve a published site from `yourbrand.com` instead of the shared
`*.r21.dev` subdomain, keeping one stable address independent of the underlying host. There's no firm
date yet; this page will be updated when it lands.

## Limitations & good to know

* **Not available yet.** The **Add custom domain** option in the Publish panel is a labeled placeholder
  ("Soon"); selecting it does not start a domain setup.
* **Use the `*.r21.dev` subdomain in the meantime.** It's a real, shareable, public URL — pick a clean
  subdomain and share that.

## FAQ

<AccordionGroup>
  <Accordion title="Can I connect my own domain right now?">Not yet. Custom domains are marked "Soon" in the Publish panel. For now, every published site uses a `your-name.r21.dev` subdomain that you choose and can rename.</Accordion>
  <Accordion title="What's the difference between a subdomain and a custom domain?">The subdomain is the `your-name` part of `your-name.r21.dev` — yours to pick, but on the shared `r21.dev` host. A custom domain is your own address, like `yourbrand.com`, which isn't supported yet.</Accordion>
  <Accordion title="Will I need to change DNS settings?">A custom domain normally involves pointing your domain's DNS at the host. The exact records and steps for Mythos aren't published yet because the feature isn't live. This page will be updated when it ships.</Accordion>
