justssdp

UPnP host discovery without anything else that doesn't matter.

Basically makes a host discoverable with normal UPnP/SSDP search for "ssdp:all", "upnp:rootdevice" or custom non-standard device-type URI: "urn:example-com:device:Example:1".

Nothing beyond that is implemented, not even the LOCATION device-type XML description in the search response.

The searching host will be able to identify the servers IP from the network stack, so the LOCATION url is not even necessary, but there is a default implementation to provide a valid URL if the ifaddr additional dependency is installed.

There is a tiny SSDP search tool to use as well for testing.
