A lightweight Go binary that moves files and relays multi-user chat over QUIC. Works from the CLI or a browser. No accounts, no cloud — just room codes.
# start the server (web UI + QUIC relay in one process) $ airsend -sw 0.0.0.0 3888 0.0.0.0 8443 → web: http://0.0.0.0:3888 · quic: 0.0.0.0:8443 # send a file, get a code $ airsend -f ./logs.tar.gz → code: wave21 # receive it anywhere $ airsend -r wave21
One binary. Two transports. Zero dependencies at the user’s side — no account, no install step for the receiver if they use the browser.
The pinout of an ECU refers to the detailed description of what each pin (or connection) on the ECU connector is used for. This can include signals, voltages, grounds, and communications lines that connect the ECU to various sensors, actuators, and other control units in the vehicle.
Files are deleted from the server after the first download. Code-based lookup (wave21, dock42). No lingering blobs.
Broadcast rooms by code. CLI TUI or browser — identical semantics.
Token bucket per IP × scope: upload, paste, download, ws. Proxy aware.
Bypass the relay entirely with -d / -ds. Pure peer-to-peer.
Protocol "airsend" over generated certs. Intentional.
