# Sleipnir

> Sleipnir is a hosted RTMP multistream relay. It takes one live
> stream from your broadcasting software (such as OBS) and relays it
> out to multiple streaming platforms - Twitch, YouTube, Kick and
> others - at the same time, without your computer or internet
> connection having to send the video more than once.

Sleipnir is for live streamers and content creators who want to
broadcast to several platforms simultaneously (multistreaming, also
called simulcasting) without overloading their PC or upload bandwidth.
You stream once, to Sleipnir; Sleipnir performs the fan-out to every
destination server-side.

## What Sleipnir does

- Accepts one RTMP/RTMPS stream from OBS or any standard streaming
  encoder.
- Relays that single stream to multiple configured destinations
  (Twitch, YouTube, Kick, Facebook, TikTok, Rumble, or any custom
  RTMP endpoint) simultaneously.
- Because the fan-out happens on Sleipnir's servers, the streamer's
  own machine and internet connection only ever upload one stream,
  regardless of how many platforms are being targeted.
- Destinations are configured once in a web dashboard.
- Offers a combined chat view that merges chat from connected
  platforms into one feed.
- Generates live, animated stream overlays with AI: describe an
  overlay in plain English and get an animated browser source that
  works in OBS and any browser-source software. Existing overlays can
  be refined with a follow-up note. Every plan includes a monthly
  overlay allowance; beyond it, prepaid overlay credits (33 cents per
  generation or refine, never expiring) cover additional generations.

## Overlay generator

Sleipnir generates live, animated stream overlays for OBS and any
browser-source software. Describe an overlay in plain English and get a
hosted browser-source URL in seconds. It produces real animated HTML,
not a static image: chat boxes that scroll, alerts that slide in, goal
bars that fill, countdowns that tick.

- Free functional widgets (countdown, starting soon, lower third) need
  no account.
- AI-generated overlays require a free account; every plan includes a
  monthly allowance, and prepaid credits (33 cents per generation, never
  expiring) cover more.
- Overlays are delivered as a capability URL you drop straight into OBS
  as a Browser Source.
- Agents and scripts can generate overlays programmatically: the
  Sleipnir MCP server at /mcp exposes a generate_overlay tool that
  returns the same capability URL. It spends the calling account's own
  allowance or credits. An assistant connects over OAuth (the account
  owner approves it on a consent page, and overlay spending is a separate
  opt-in); a script uses a Sleipnir personal access token. Connection
  instructions, permissions and limits: https://sleipnir.tv/agents
- No account? A public, keyless MCP server at /mcp-quote lets an agent
  buy a single overlay for a human: quote_overlay returns a $1 Stripe
  checkout link, the human pays (no login), and get_quote_status then
  returns the capability URL. The $1 includes two refinements via
  refine_quote, and a failed generation is refunded automatically.

## Key facts

- Hosted in Europe.
- Sleipnir does not decode, analyse, or share the content of streams
  that pass through it. It relays the stream; it does not inspect it.
- No watermark is added, on any tier, including the free tier.
- No ads.
