CastwideStream once.
Go live everywhere.
Castwide is a free Windows app. OBS sends one stream to Castwide, and Castwide sends it to Twitch, YouTube, Kick, Rumble, X, Facebook and TikTok at the same time.
How it works
Three steps. A setup guide walks you through them the first time, and you can skip any step.
Point OBS at Castwide
Castwide can set OBS up for you in one click (with Undo), or show you the Server and Stream Key to copy. Works with OBS Studio and Streamlabs Desktop.
Pick your platforms
Sign in to fill in your stream keys, or paste a key yourself. Turn each destination on or off with one switch.
Press Go Live
Start streaming in OBS, check the preview in Castwide, then press Go Live. Castwide sends your stream to every platform you picked.
Everything you need to stream to more places
Built to be easy. Every warning in Castwide comes with a "?" that explains it in plain English, with simple steps to fix it.
Every platform at once
Twitch, YouTube, Kick, Rumble, X, Facebook, TikTok, or any RTMP/RTMPS server. Your stream goes out unchanged, or you can pick a quality per destination.
Vertical too
Send a 9:16 vertical version to platforms like TikTok from the same stream.
All your chat in one place
Chat from Twitch, YouTube, Kick, Facebook and Rumble in one feed, with a chat overlay for OBS.
Chat and alert overlays
Design your chat box and alerts, then add them to OBS in one click. Update them while you're live.
Alerts for everything
Follows, subs, gift subs, raids, cheers, Super Chats, memberships and more, from each platform.
Donation alerts
Connect Streamlabs or StreamElements and tips show up as donation alerts on stream.
Go-live announcements
Post to your Discord server when you go live. You can also post to X with your own X developer keys.
Speed test and bitrate advice
Check your upload speed and get a bitrate that works for all your destinations. Apply it to OBS in one click.
Setup guide
Connect OBS, sign in, run a speed test and do a test stream that goes nowhere. About 3 minutes.
Updates itself
New versions download from GitHub. Castwide waits until your stream has ended before restarting.
Never starts by itself
Castwide never adds itself to "Start with Windows". It only runs when you open it.
Private by design
Stream keys and sign-ins stay on your PC, encrypted by Windows. Crash reports are saved on your PC and never sent anywhere automatically.

Supported platforms
Sign in to Twitch, YouTube, Kick and Facebook to fill in your stream key and set your title. For the others, paste the stream key from the platform's dashboard.
Free forever. No account. No tracking.
There is no paid tier, no licence key and no account with us. Castwide doesn't collect anything about you.
- No data collection. No analytics, no telemetry, no ads.
- Your keys stay on your PC. Stream keys and sign-ins are encrypted by Windows and are never sent to us.
- Crash reports stay local. If you want help, you choose to upload one on this website.
- This website has no cookies and no trackers either.
System requirements
- Windows 10 or Windows 11, 64-bit. There is no Mac or Linux version.
- OBS Studio or Streamlabs Desktop to send your stream.
- Enough upload speed for all your destinations added together. Each destination uploads separately, so 3 destinations at 6,000 kbps need about 18 Mbps. The built-in speed test checks this for you.
- FFmpeg is included. Nothing else to install.
First launch: Castwide isn't code-signed yet, so Windows may show "Windows protected your PC". Click More info, then Run anyway. If Windows Firewall asks, choose Allow (only needed if OBS is on another PC).
