In their own words
DualStream Relay
DualStream Relay sends a stream from a PC to DualStream’s servers, which distribute it to Twitch, YouTube, Kick, and custom RTMP destinations. Twitch, YouTube, and Kick can be connected with one click, without copying stream keys. If the connection drops, Disconnect Protection keeps destination platforms live on a custom standby screen and resumes streaming after reconnection. You can upload the screen viewers see during an interruption. Output support varies by destination: up to 2160p60 on YouTube, 2K on Twitch with Enhanced Broadcasting, and 1080p60 on Kick, Facebook, TikTok, and custom RTMP. Relay is available on Windows, macOS, and iOS. The free Test Drive plan includes instant replay clips with a watermark. Premium includes multistreaming, Disconnect Protection, and watermark-free clips; it costs $9.99 a month, with the first 30 days free, or $99 a year. One Premium subscription covers the Windows and macOS apps, iPhone app, OBS plugin, and MCP server.
