Live mode has three choices, picked on the Content tab of the webinar. Settings, then Live Streaming, holds the default for new webinars.
This site, no account needed:
Your camera and screen go straight from your browser to your own WordPress site, and your attendees watch inside your room. There is nothing to sign up for and nothing to install. Choose Camera, Screen or Screen + Camera and click Start broadcasting. Viewers are a few seconds behind you, which is normal for a broadcast. It works in Chrome, Edge and Firefox, and browsers only allow camera and screen capture on secure https sites.
Because the video is served by your own hosting, this option suits a normal room rather than a crowd of many hundreds. For a crowd, use Cloudflare Stream. It is a one way broadcast: attendees watch and chat, they do not appear on camera. Your uploads folder must be writable, and the console tells you if it is not.
It records itself. When you stop, the recording is filed in your Media Library and set as your replay automatically.
Cloudflare Stream, for very large rooms:
Connect your own Cloudflare Stream account under Settings by entering your Account ID and an API token that has the Stream Edit permission. Cloudflare then carries the video instead of your host, with adaptive quality, and bills you directly for what you use. The video is published from your browser over WebRTC to your Cloudflare account, and attendees in the room subscribe to the playback stream. There is no OBS and nothing to install.
Embed an external stream:
Paste the embed URL of a stream you are already running, for example an unlisted YouTube Live. Your registration, chat, timed offer and tracking all stay inside your own room. This needs no extra account and no configuration beyond the URL.
Finding the Go Live console:
Go Live sits on the Content tab of a Live webinar, and the Go Live button at the top of the editor reaches it from any tab. Set the date and time on the Schedule tab. Your room opens with a countdown, people arrive, and you press Start broadcasting when you are ready. Nothing goes out before you press it.
While you are live:
The console gives you extra controls: post a message to the room chat as the host, and show the offer to everyone immediately. Attendees who were already sitting in the waiting room pick the stream up automatically the moment you start, without refreshing. For the full host cockpit, see The Host Chat Console.
Choosing what you share:
Your browser asks for your screen first, and then for your camera and microphone if you chose them. If your screen cannot be captured, the console explains why instead of quietly switching to your camera. The console names what is going out before you start. Your source is locked while you are broadcasting, so press Stop to change it.
When you stop:
With This site, the recording is already saved and set as the replay. With Cloudflare Stream, Cloudflare records the broadcast automatically and the plugin tries to attach that recording as this webinar's replay straight away. Cloudflare usually needs a few minutes of processing first, so if it is not ready the console tells you, and the Use my live recording as the replay button in the Live panel fetches it when it is. The live input itself is kept rather than deleted, so repeat broadcasts reuse it and the recording is not orphaned.
About streaming capacity and cost:
Cloudflare fans the stream out to viewers with adaptive quality, and the plugin is built around a target of up to 500 viewers for a Cloudflare broadcast. Streaming is billed by Cloudflare directly to your own account on a pay as you go basis, so check their current pricing yourself. AI Deck, Recorded and This site webinars need no streaming account at all.
Checking the connection:
Settings has a Test connection button for Cloudflare, and Diagnostics reports whether your token was accepted or needs the Stream Edit permission.
