Can I use UBOS without purchasing a domain name?

/docs/users/faq-howto-troubleshooting/howto-nodomain/

Yes:

  • You can use the IP address of your Device instead of a domain name, if you have specified *, or the IP address directly as the domain name when executing ubos-admin createsite.

  • If you are satisfied with accessing your Device only on your local network, the UBOS device advertises itself via mDNS and you can use that name. See {{ % pageref networking.md %}}

  • You can enter a domain name for your Site name in your /etc/host file(s) or in the local DNS server of your home router. This makes most sense if your Site is only on your local network anyway.

  • You can use a free dynamic DNS service.
