Red Warden MultistreamFree plugin for OBS Studio
Red Warden Multistream sends your OBS stream to YouTube, Twitch, Kick, TikTok, Facebook, Rumble, X or any RTMP server at the same time. Press Start Streaming in OBS. That's it.
Built-in presets
How it works
Close OBS, run the installer, open OBS. The plugin appears under Docks > Red Warden Multistream.
Click Add destination, pick a platform, paste its server and stream key. OBS keeps streaming to the platform in its own Settings > Stream; add every other platform here. Moving from obs-multi-rtmp or Aitum Multistream? The dock offers to import your destinations.
Every platform you switched on starts with OBS, and stops when OBS stops. Each card shows whether it connected. Flip a platform on or off at any time, even mid-stream.
Features
At a glance
Each platform gets a card: live or not, how much it's sending, and which encoder it uses. The header counts how many are live and how much of your upload the whole stream is using.
It still fits a slim OBS dock.
Light on your PC
By default a platform shares OBS's own encoder: OBS encodes your stream once and every platform gets that same video and audio, so adding a platform adds no encoding work (just a little to send it).
When a platform needs something different (a lower bitrate, a 720p version, a different audio bitrate or track), give it its own encoder. Its audio starts out matching OBS's own bitrate and track.
Upload headroom
Multistreaming sends a full copy of your stream to every platform, so upload adds up fast. The dock adds it up for you against your real upload speed (measure it with the built-in speed test while you're offline, or type it in), and warns you before you run out of headroom: an amber note above 75%, red above 90%.
Platform advice
If a platform's published limits don't fit your settings (video bitrate, resolution, frame rate, keyframe interval, audio bitrate), the card says so in plain words, using the same platform data OBS ships with. It never guesses limits for a platform OBS doesn't list.
Account safety
Streaming platforms guard their servers against floods of connections, and they don't publish where the line is. So the plugin gives every platform a hard connection budget:
Every attempt the plugin makes counts: the first connect, reconnects, retries, the Twitch bandwidth test, even you mashing Retry. When the budget is spent, the card says it's pausing to protect your account, and when it will try again.
A rejected stream key or a broken server URL is never retried automatically. Retrying those can only hammer the platform, so the card tells you what's wrong and points you to Edit instead.
Auto-reconnect
If a platform drops your connection, the plugin reconnects on its own: after roughly 5 seconds, then 10, 20, 40, then about once a minute, always inside the connection budget (if it still can't get through after ten tries, it keeps trying every couple of minutes). The other platforms keep streaming untouched.
A connection that stays open but stops sending data is noticed and restarted too.
Stream report
When you stop, the dock tells you in one line how the stream went. Open the report for every platform: how long it was live, every drop and recovery with timestamps, and how much it sent.
The last 50 reports are saved, and you can copy one to share.
Twitch
Twitch has a bandwidth-test mode: it receives your stream but never shows it to anyone. One click in a Twitch destination's settings runs a test of about 20 seconds and tells you whether your connection to that Twitch server holds your bitrate.
Switching over
Red Warden Multistream finds destinations saved in obs-multi-rtmp and Aitum Multistream and offers to import them, with their bitrates and encoder where it can read them (check each one's settings before you go live).
Imported destinations start switched off, so nothing goes live until you turn it on. (SRT destinations aren't supported yet; RTMP and RTMPS are.)
Every platform gets its own on/off hotkey in OBS's Settings > Hotkeys, plus "all on" and "all off". Bind them to Stream Deck keys. Streamer.bot, Touch Portal, SAMMI and scripts can list and switch platforms through obs-websocket.
Keys are kept in Windows Credential Manager, never in a settings file. The plugin also refuses a server URL that has your key pasted into it, because OBS writes server URLs into its log file.
Once each time OBS starts, the plugin checks for a newer version and, if there is one, shows a single line in the dock with a Download link. It never downloads or installs anything by itself, and you can switch the check off in the dock's menu.
Platforms & privacy
Built-in presets, with a hint on each telling you where to find the server and key:
Plus Custom RTMP for anything else that takes an rtmp:// or rtmps:// address (Restream, a self-hosted relay, other platforms). SRT isn't supported yet.
No account and no telemetry. The plugin only connects to:

Update: run the newer installer the same way. It replaces the plugin and keeps all your platforms and stream keys.
Uninstall: Windows Settings > Apps > Installed apps > Red Warden Multistream (OBS plugin). Your platforms and keys are left in place, so reinstalling picks them back up. (Removing one platform in the dock is different: that also deletes its saved stream key.)
No installer? Copy the rws-multistream folder from the zip into C:\ProgramData\obs-studio\plugins\.
FAQ
Yes. No paid version, no watermark, no limits, no account. It's open source under the GPL.
Not noticeably, by default. Platforms share the encoder OBS is already running, so adding one costs upload bandwidth and a little sending work, not another encode. Only a platform you give its own encoder adds encoding work.
Every platform gets its own full copy of the stream. OBS's own stream plus three more platforms at 6 Mbps each need about 24 Mbps of upload. The dock adds this up for you and warns before you run out.
Exactly where it always did: the platform in OBS's Settings > Stream. Add your other platforms in the dock. They all start and stop with OBS's Start Streaming button.
Only that one is affected. It reconnects by itself, and the others keep streaming.
That's exactly what the connection budget is for. The plugin never makes more than 12 connection attempts to a platform in 10 minutes or 40 in an hour, and never retries a rejected key by itself.
Yes: with its switch, a hotkey, a Stream Deck key, or an obs-websocket tool like Streamer.bot.
Not yet: Windows only for now.
The dock offers to import your destinations. Once you've switched, remove them from the old plugin: it keeps stream keys in a plain-text settings file.
Most free streaming tools are unsigned: Windows calls the publisher "Unknown", and you have no way to know who made the file or whether it was changed. This one is signed by Red Warden Studios LLC, so Windows shows exactly who published it, and the signature breaks if anyone tampers with the file. (A brand-new download can still get a SmartScreen "not commonly downloaded" notice for its first days while it builds reputation; the publisher name is how you know it's the real one.)
Yes, it's GPL. The names "Red Warden", "Red Warden Studios", "Red Warden Multistream" and the logos are trademarks and aren't covered by the GPL, so a modified version needs its own name and logo.
Email support@redwardenstudios.com. The stream report (Copy report button) is the most useful thing to include.
