What Sleipnir is

Sleipnir is a web service that relays one livestream to multiple destinations. It can take a stream from its built-in browser encoder, OBS, or another RTMP encoder, then distribute it to Twitch, Kick, YouTube, and destinations added through custom RTMP. The maker says video passes through without decoding and without perceptible delay. Your computer uploads one stream, while Sleipnir fans it out server-side, so adding destinations does not multiply upload demand. The service supports up to eight destinations in its product description, with plan allowances of three on Free, five on Standard, and eight on Pro; the listed simultaneous-destination figure is five. Users can describe overlays in plain English and receive animated browser sources with options such as chat, alerts, goals, and countdowns. StreamTeam adds shared live-status pages and direct platform streaming. An MCP server lets approved assistants manage destinations and teams, with separate consent for overlay generation. Sleipnir runs on the web and offers a free plan plus paid monthly tiers.
