Global Send lets you send encrypted messages anywhere in the world without signing up for any account. It achieves better speed and latency by using direct connections instead of sending messages through a central server
This app still uses relay servers to discover the address of the recipient before making the direct connection. By default it uses public relays maintained by n0.computer, but you can deploy your own relay server using the Rust library iroh_relay and use it instead: https://docs.rs/iroh-relay/latest/iroh_relay/index.html
On the other hand, since there is no server to fetch messages, this app need to constantly run in the background to receive them
