Free OBS Multichat for Twitch, YouTube & Kick
Keep supported streaming conversations together without switching between separate chat windows.
Multichat is part of FDGCast, the same OBS streaming companion that includes chat, multistream controls, activity and monitoring.
Why use Multichat?
During a multistream or collab, viewers can be talking on several channels at once. A combined view helps you follow the conversation while keeping its platform and original channel visible.
How Multichat works
The Combined Chat dock displays messages from linked Twitch, YouTube and Kick accounts. Platform icons distinguish incoming messages; channel labels keep the original broadcaster visible. Twitch shared-chat provenance uses the source broadcaster and message identity to preserve origin context and avoid showing the same shared message repeatedly.
- Filter by platform or channel, pause the feed and use Jump to latest when you are ready to catch up.
- Twitch shared-chat labels identify where a message started; combining feeds does not merge the platform communities or their permissions.
- Chat requires authorized accounts and available live chat. YouTube quota and Kick webhook delivery can affect availability independently.
- TikTok LIVE chat is available through an experimental, receive-only username reader in Companion. The creator must have a public LIVE running; FDGCast does not need to send video to TikTok.
Multichat in the OBS workspace
A practical streaming example
You and a friend are co-streaming with Twitch shared chat while you also stream to YouTube and Kick. Read those messages in the same dock, using the platform and channel labels to know which audience you are answering.
Set up Multichat
- Install FDGCast and connect your Twitch, YouTube or Kick accounts in Hub Settings → FDGCast.
- Generate a pairing code, enter it in Companion, and connect Companion to OBS WebSocket.
- Open the FDGCast Chat dock from OBS Docks. Start a supported live broadcast and check incoming messages from each connected platform.

Multichat questions, answered
Is OBS multichat free?
Yes. Core combined Twitch, YouTube and Kick chat is free. Live custom overlays are a separate Supporter feature.
Does it show which platform a message came from?
Yes. Platform identification and original-channel context help distinguish messages in the combined feed.
How does Twitch shared chat work?
FDGCast preserves shared-chat source broadcaster information and deduplicates shared message identities. Use the origin labels to see which channel a message started in.
Can I filter or pause the combined chat?
Yes. Platform/channel filters, Pause and Jump to latest let you control which conversations you follow.
Can I read TikTok LIVE chat without streaming through FDGCast?
Yes. In Companion → Connections, enter the creator’s TikTok username and enable the experimental reader. The creator must have a public TikTok LIVE running through a phone, LIVE Studio or another encoder. No TikTok video output from FDGCast is needed. This reader is receive-only.
