Smee.io is a public webhook payload delivery service built around Server-Sent Events. The smee-client CLI forwards payloads received by a smee.io channel to a local URL, which gives a host behind NAT or a firewall a way to receive inbound HTTP callbacks without exposing a listening port.
Subscribes to a smee.io channel and forwards every payload it receives to a local HTTP endpoint.
