Port 8090 is commonly utilized as an alternative HTTP port, especially when the default port 80, or the primary alternative 8080, are already occupied or restricted. It facilitates HTTP web traffic, enabling access to web services and applications through an alternative entry point. This port is popular in development environments, custom web server deployments, proxy services, and certain web platforms where port conflicts might arise.

Which one is on your host

ask the machine, not the registry

The registry says what 8090 is registered to. What is listening on it right now is decided by the host, and only the host can be asked. Each of these prints the process behind the socket.

linux
ss -ltnp | grep ':8090\b'
macos
lsof -nP -iTCP:8090 -sTCP:LISTEN
windows
netstat -ano | findstr :8090

On Linux and Windows the process name comes back with the socket; on macOS lsof needs sudo to name a process that isn't yours. Match what it prints against the 2 entries above.

A port number is not a service. Anything may listen on 8090 — what you actually met is decided by the host, not the registry. If a service is missing here, it belongs in the registry.
