iroh is fully open source though, you can run your own relay server and not have any dependencies on number0

Headscale exists, not sure what the difference is in practice.

This might not be a giant difference in practice.

But headscale is a community project. The iroh relay code is by number0 just like iroh itself and lives in the same MIT and Apache2 licensed repository. You can even embed it into your webserver if you have a special use case - it is very modular.
