Custom Domains
Pro plan feature — bring your own domain for tunnel URLs.
Custom domains let you use your own domain instead of *.tunnel.nullbore.com.
Setup
-
Add a CNAME record pointing your domain to NullBore:
tunnel.yourcompany.com → tunnel.nullbore.com -
Configure the domain in your dashboard or via API (coming soon)
-
Open tunnels with your domain:
nullbore open --port 3000 --domain tunnel.yourcompany.com
NullBore automatically provisions a TLS certificate for your domain via Let's Encrypt.
Self-hosted
On a self-hosted server, custom domains work by adding the domain to your server's TLS configuration:
nullbore-server \
--tls-domain tunnel.yourdomain.com,tunnel.yourcompany.com
Status: Custom domain support is coming soon. The infrastructure is in place (per-domain ACME), but the dashboard integration and client flags are in development.
