Custom domains

Every project gets a free *.nimbus.dev subdomain, but you’ll usually want to serve functions from your own domain.

Add the domain to your project:
Terminal window
```
nimbus domains add api.example.com
```
Nimbus prints a DNS record to add at your registrar:
```
Type   Name   Value
CNAME  api    edge.nimbus.dev
```
Add that record with your DNS provider.
Verify it’s connected:
Terminal window
```
nimbus domains verify api.example.com
```

Wildcard domains

To route an entire subdomain tree to a single function (useful for multi-tenant apps), add a wildcard record instead:

nimbus domains add "*.example.com"

Each request’s Host header is available on request.headers.get('host') inside your function, so you can branch per-tenant in code.
