Restream.io is the cross-platform multi-streaming service that takes one stream input from your encoder and rebroadcasts it to multiple platforms simultaneously. The setup runs through your OBS or Streamlabs configuration: instead of streaming to a platform's ingest server directly, you stream to Restream's server, which then fans the broadcast out to every connected platform.

The setup steps: create a Restream account, link the platforms you want to broadcast to (Restream supports the major platforms including Twitch, YouTube, Kick, X, Facebook), copy the Restream stream key, paste it into your OBS Stream settings as the destination. Save and test.

The pricing model: a free tier supports a limited number of simultaneous platforms with basic features, with paid tiers unlocking additional platforms, custom RTMP destinations, and analytics features.

The trade-off to be aware of: any added relay introduces minimal latency, and a Restream outage affects all your destinations simultaneously. For most streamers, the convenience of unified configuration outweighs the trade-off. Configure once, stream everywhere.
