Subdomains

Every service you add gets a public URL on seawise.dev.

How Subdomains Work

When you add a service, SeaWise assigns a subdomain automatically:

https://myapp-abc123.seawise.dev

The subdomain is unique across all of SeaWise. No one else can claim the same subdomain.

Custom Subdomains

You can choose your own subdomain for a cleaner URL:

https://plex.seawise.dev
https://homeassistant.seawise.dev

To set a custom subdomain, go to the service settings in the SeaWise dashboard.

Subdomain Rules

• 3 to 63 characters

• Lowercase letters, numbers, and hyphens only

• Cannot start or end with a hyphen

• Must be unique (not already taken by another user)

DNS & HTTPS

• All service URLs use HTTPS with valid TLS certificates

• Certificates are managed automatically — no configuration needed

• DNS is handled by SeaWise — no need to set up your own DNS records
