> Share LiveDemos and AI Demo Agents from your own subdomain, like demos.acme.com, with one CNAME record and automatic HTTPS.

Canonical: https://livedemo.ai/docs/share/custom-domain/

# Custom domain

Share `https://demos.acme.com/livedemos/…` instead of a LiveDemo link. Available on the Growth plan. Only the workspace Admin can set it up.

## Requirements

- A subdomain you own, such as `demos.acme.com`. Root domains like `acme.com` can't be used.
- Access to its DNS settings.

## Set it up

1. Open **Settings → Security & domain → Custom domain**.
2. Enter your subdomain and click **Add domain**.
3. Add the record LiveDemo shows at your DNS provider:

| Type | Name | Target |
| --- | --- | --- |
| `CNAME` | `demos` | `custom.livedemo.ai` |

4. Click **Verify**. It can take a few minutes. The status changes from **Pending** to **Active**.

HTTPS certificates are issued and renewed automatically.

### DNS providers

| Provider | Where |
| --- | --- |
| **Cloudflare** | **DNS → Records → Add record**. Set the proxy status to **DNS only** (grey cloud) |
| **GoDaddy** | **My Products → DNS → Add New Record → CNAME** |
| **Amazon Route 53** | **Hosted zones → your domain → Create record**, type `CNAME` |
| **Namecheap** | **Domain List → Manage → Advanced DNS → Add New Record** |
| **Google Cloud DNS** | **Cloud DNS → your zone → Add standard** |

## What changes

Once **Active**, links you copy in LiveDemo use your domain:

| Link | Uses your domain |
| --- | --- |
| Demo share link (**Copy link**) | ✓ |
| [Custom links](https://livedemo.ai/docs/share/custom-links/) | ✓ |
| Website embed code | ✓, `https://demos.acme.com/livedemos/DEMO_ID?step=1` |
| AI Demo Agent share link | ✓ |
| AI Demo Agent embed script | No, it keeps loading from LiveDemo |
| Medium link | No |

[URL parameters](https://livedemo.ai/docs/share/url-parameters/) work on your domain too.

Links you already shared on LiveDemo's domain keep working.

## Remove it

Click **Remove** and confirm. Links on that domain stop working. LiveDemo links keep working.

## Troubleshooting

- **Stays Pending**: check the CNAME with `dig demos.acme.com CNAME` or an online DNS checker. The red message under the record shows what LiveDemo is waiting for.
- **Cloudflare**: the record must be **DNS only**. A proxied (orange cloud) record blocks the certificate.
- **CAA records**: if your domain has CAA records, allow `letsencrypt.org` and `pki.goog` so the certificate can be issued.
- **"Use a subdomain you own, like demos.acme.com"**: you entered a root domain or a LiveDemo domain.
- **"This domain is already used by another workspace"**: remove it from the other workspace first.
