WAI

The wai command line, and the reference software wai dev runs on your own machine. All of it is open source under Apache-2.0, built from the open-standards repository (wai/quickstart/build.sh).

File	What it is
bin/wai	The command line: hello, create, dev, verify, and the envelope tools (inspect, wrap, unwrap, encode, decode for the mandatory floor, capabilities)
bin/wai-relay	The relay a room's media goes through: MOQT over QUIC, WebTransport and WebSocket
bin/wai-room	The room service: a room's keys, its grants, its clock
bin/wai-ingest	The ingest gateway: WHIP, SRT and RTMP into a room, each group signed at the first hop, and WHEP out
bin/wai-remote-host	A remote desktop room's host agent
bin/wai-pack	The packager: a title as WAI objects, HTTP playlists and a MoQ catalog
bin/wai-quantum	The quantum command line: OpenQASM programs run on this machine, the result signed
share/wai/web/	The room client a browser loads: its pages and their WebAssembly
share/wai/studio/	WAI Studio, which wai dev serves at /_wai/

Start

wai hello                                   # WAI's four steps on a sample: name, dispatch, rebuild, receipt
wai create my-room --template video-room    # a video room in one page
cd my-room
wai dev                                     # the relay, the room service and your page, on 127.0.0.1:8080
wai verify ../wai-hello                     # the receipts hello wrote, checked offline

wai create --list names every template. wai dev --help gives its options. Nothing here needs an account, and nothing is sent off your machine.

Keep bin/ and share/ side by side: wai dev finds the relay, the room service, the room client and Studio beside itself. Homebrew and Scoop install wai-quantum as a package of its own, which wai depends on.

Ports

What each program listens on by default, on 127.0.0.1. wai dev serves everything on one origin and runs its own relay and room service on free ports behind it; the other rows are each daemon's own default, as its example configuration or its source sets it, for running it alone. No two of them share a port, so any of them run side by side. A deployment sets its own.

Port	Program	What	Set by
8080	wai dev	your page at /, the room service at /room-api/, the relay at /moq, Studio at /_wai/	--port
4443/udp	wai-relay	MOQT over QUIC, and WebTransport	quic_listen
4480	wai-relay	MOQT over WebSocket	websocket_listen
9682	wai-room	the room service's HTTP API	listen
8088	wai-ingest	WHIP and WHEP	[http] listen
1935	wai-ingest	RTMP	[rtmp] listen
1936	wai-ingest	RTMPS, off until set	[rtmp] tls_listen
5167	wai-ingest	SCTE 104 automation, off until set	[injector] listen
9000/udp	wai-ingest	SRT, off until set	[contrib.srt] listen
9694	wai-audit	the audit collector	WAI_AUDIT_ADDR
8251	wai-ledger	the receipt ledger	WAI_LEDGER_ADDR
8252	wai-fleet	the fleet service	WAI_FLEET_ADDR
8241	wai-quantum-service	the quantum job service	WAI_QSVC_ADDR
9670	wai-world-relay	the interactive worlds' relay	WAI_RELAY_BIND
9690	wai_stitched_presentation serve	the stitched presentation verifier	--listen
8380	wai http origin	an HTTP origin of WAI objects	--port

A program that reaches another names that one's port: the room service's relay_url is the relay's WebSocket (ws://127.0.0.1:4480/moq), and the ingest gateway's [relay] addr is the relay's QUIC endpoint (127.0.0.1:4443). joule-moq-room's tests/ports.rs holds every row to the program that serves it.
