Portlify gives a process on your machine a public address. The CLI opens an outbound WebSocket to the edge. Incoming HTTP or TCP is forwarded down that connection to localhost. Nothing inbound needs to be open on your network.
HTTP gets a hostname on *.portlify.ru. TCP and SSH get a public port on the edge. While a tunnel is up, request logs show in the local inspector at http://localhost:4040 and in the dashboard.
The HTTP API at
https://api.portlify.ru is for accounts, keys, listing tunnels, and logs. Opening a tunnel still needs the CLI (or another agent) connected to the edge.
