Rumble is the platform most multistream chat tools skip. Combined Chat reads Rumble live chat in the same feed as Twitch, Kick and YouTube, with no login and nothing to install. Type the channel name and it connects.
Rumble's official Live Stream API is keyed to one creator and only exposes that creator's own channel, a few dozen messages at a time. That works for a streamer reading their own chat and for nothing else. It cannot serve a viewer, a moderator, or anyone watching a channel they do not own, so tools built on it either leave Rumble out or make it creator-only.
In the Rumble box, type the channel name as it appears in the channel's
URL, for example grahamallen from
rumble.com/c/grahamallen or rumble.com/user/grahamallen,
and press Add. That is the whole setup. Both kinds of Rumble address work,
since some accounts live under /c/ and some under
/user/.
If you would rather point at one specific stream, pasting a popout chat link
(rumble.com/chat/popup/...) still works. That link identifies a
single broadcast rather than the channel, so it stops working when the next
stream starts. The channel name does not have that problem.
Rumble chat is read-only in Combined Chat for now. Sending messages and moderating are available on Twitch and Kick, where the platforms provide the means to do it on your behalf. Rumble does not offer that to third-party tools in a way that works for anyone other than the channel owner.
If you multistream to Rumble and somewhere else, or your community is split between Rumble and Kick, this is the point: one window, every chat. See the setup guide to get all four running, the OBS overlay page to put Rumble chat on stream, or the comparison for how other tools handle Rumble.
