Multistream Bandwidth Calculator

How much upload do you need to multistream?

There are two ways to stream to more than one platform at once, and they cost very different amounts of upload.

Locally, from your PC. Desktop multistream plugins open a separate connection to each platform and send a full copy of your stream to every one. Your upload requirement is your bitrate times the number of platforms. At 6 Mbps to four platforms that is 24 Mbps of sustained upload, plus the headroom real streaming needs on top. Most home connections do not have that much upload, and each extra output also adds encoding load to your CPU.

Through a relay. You send a single stream up once, to the relay, and the fan-out to every platform happens on the server. Your home connection only ever uploads one copy of your stream, so going from one platform to eight does not change your upload at all. A modest connection reaches as many platforms as a fast one.

Sleipnir is a relay built for exactly this. See how multistreaming to Twitch, YouTube and Kick at once works, or start free from the calculator above.

Why local multistreaming chokes a home connection

Upload is the scarce direction on almost every home internet plan. A line that downloads at 500 Mbps might only upload at 10 or 20. Streaming already wants stable headroom above your bitrate, so when local multistreaming multiplies that bitrate by every platform, even a good connection runs out of room fast. That is the exact problem a relay removes: the multiplication happens on the server's bandwidth, not yours.
