v1.0 // Go + QUIC + WebSocket

6 Portable — Cutting Optimization Pro

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.

~/airsend
# 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
Features

Everything you expect.
None of the bloat.

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 upcoming Version 6 introduces several features that make the software more intuitive: cutting optimization pro 6 portable

Always input the exact thickness of your saw blade or laser cutter to prevent final parts from turning out too small. [Define Materials] ➔ [Input Target Parts] ➔ [Configure

Because this is the portable edition, it delivers full optimization power straight from a USB drive without requiring a standard installation. What is Cutting Optimization Pro 6 Portable? Will you be feeding this data into a or a CNC machine

Will you be feeding this data into a or a CNC machine ?

Version 6 of the software works with both (like pipes, bars, and tubes) and two-dimensional (2D) materials (such as sheets of wood, glass, and metal). It's particularly valuable for industrial applications, helping to streamline production and manage inventory more effectively. A key feature is its ability to work with complex products (such as tables, desks, or cabinets) by automatically computing the sizes of all the pieces needed.

One-shot file pickup

Files are deleted from the server after the first download. Code-based lookup (wave21, dock42). No lingering blobs.

Multi-user chat rooms

Broadcast rooms by code. CLI TUI or browser — identical semantics.

Rate limited by scope

Token bucket per IP × scope: upload, paste, download, ws. Proxy aware.

Direct P2P mode

Bypass the relay entirely with -d / -ds. Pure peer-to-peer.

Self-signed TLS

Protocol "airsend" over generated certs. Intentional.

How it works

Three commands. One code.
