Install
- 1
Download the signed installer
Grab StreamFusion-Setup-x.y.z.exe from download.aquilo.gg/streamfusion (auto-redirects to the latest release on GitHub).
- 2
Run it
It's signed, Windows SmartScreen may still flash once on the very first install because the publisher is new. Click More info → Run anyway.
- 3
Launch StreamFusion
First run drops you straight into the unified chat feed. The auto-updater takes over from here, every future update installs silently in the background.
Since 1.4.5 there's no install modal, updates apply on next launch. If you want to pin a specific version, disable updates in Settings → Updates.
Connect Streamer.bot
StreamFusion pulls Twitch + YouTube + Kick chat through Streamer.bot's WebSocket server. Set this up once and StreamFusion auto-reconnects every launch.
- 1
Enable the WebSocket server in Streamer.bot
Streamer.bot → Servers/Clients tab → WebSocket Server: Enable. Note the host (127.0.0.1), port (default 8080), endpoint (/), and password (set one).
- 2
Paste those into StreamFusion
StreamFusion → Settings → Connections → Streamer.bot. Host, port, endpoint, password. Hit Connect.
- 3
Confirm the bridge
The LIVE bar lights up the platforms Streamer.bot is connected to. If Twitch is grey, your SB Twitch login expired, re-auth there, not in StreamFusion.
Anyone who can hit your machine on that port can fire SB actions if the password is weak. Pick a long random string; treat it like any other secret.
Add TikTok via TikFinity
TikTok doesn't expose a public chat API. TikFinity scrapes TikTok LIVE on your behalf and exposes a local WebSocket, StreamFusion treats it like another chat source.
- 1
Install TikFinity + log in
Get TikFinity from tikfinity.zerody.one. Sign in with your TikTok creator account.
- 2
Enable TikFinity's WebSocket
TikFinity → Settings → Developer → WebSocket Server: ON. Default port 21213.
- 3
Auto-detect in StreamFusion
StreamFusion polls localhost:21213 on launch, if TikFinity is running, TikTok chat appears in the feed within seconds. Manually re-detect from Settings → TikTok if needed.
Pop-out chat overlay
The pop-out is a frameless transparent window you drop on top of your OBS game capture. Same chat as the main window, no chrome, fits into the corner of any layout.
- 1
Open the pop-out
Top bar → Pop Out. A new window appears, drag it onto your stream-side monitor and position over the gameplay area you want chat to live on.
- 2
Toggle click-through
The unlock button on the pop-out title bar = click-through OFF (you can drag / resize). The lock button = click-through ON (mouse passes through, gameplay still captured).
- 3
Capture in OBS
OBS → + → Window Capture → pick the pop-out window. Use the 'Windows 10' capture method for transparent backgrounds. Crop with Alt-drag if needed.
Big events (subs, gift bombs, raids, hype-train level-ups) fire from a separate transparent banner window that floats centered over the canvas. Capture it with a second Window Capture source if you want it on stream.
Patreon link
Every StreamFusion feature is free for everyone. Linking Patreon is optional, it gives Patrons early access to brand-new features before they roll out to the public. The app checks your patron status automatically every launch, no token typing.
- 1
Sign in
Settings → Patreon → Sign in. Browser opens, you authorize on Patreon's site, app picks up the token automatically.
- 2
Wait for the patron-status check
First sign-in takes a few seconds while the Worker validates. The Patreon chip turns green when your patron status is confirmed.
- 3
Early-access features turn on
Patrons get brand-new features early, they appear right inside the same build, no separate install. Every feature still rolls out free to everyone shortly after.
Troubleshooting
Check Streamer.bot is running + WebSocket Server is enabled. The LIVE bar in StreamFusion should show platforms in color, not grey. If grey, SB isn't connected; re-auth the platform inside SB.
TikFinity occasionally drops its WebSocket when TikTok's API rate-limits. Restart TikFinity; StreamFusion auto-reconnects within ~5 seconds.
OBS's Window Capture needs to use the 'Windows 10 (1903 and up)' method for transparent windows. Right-click source → Properties → switch capture method.
Usually a transient GitHub rate-limit. Wait an hour and try again, or download the latest installer manually from download.aquilo.gg/streamfusion.
