OBS: Stream to Two Platforms Free

Twitch announced at TwitchCon on Oct. 20, 2023, that it would allow creators to simulcast to rival platforms, a policy shift announced by CEO Dan Clancy during the keynote. (techcrunch.com) Twitch followed with contract changes in its updated Monetized Streamer Agreement that removed several exclusivity clauses — including the old 24‑hour VOD restriction — and asked partners to review the new terms. (help.twitch.tv) OBS users can avoid paid relays by installing the community "obs‑multi‑rtmp" plugin, which exposes multiple RTMP outputs inside OBS and can share encoders to reduce CPU overhead. (github.com) That plugin saw an OBS‑32 compatible release on Oct. 25, 2025, showing active maintenance and cross‑platform packaging for Windows, macOS and Linux. (github.com) Cloud relays remain popular: Restream’s free tier supports streaming to two destinations simultaneously, while its Standard plan ($19/month or billed annually at an effective $16/month) expands destinations and removes Restream branding. (restream.io) Layout and format tooling has matured — Aitum’s Vertical plugin adds a separate portrait canvas for TikTok/YouTube Shorts and its Stream Suite bundles multistream docks and multi‑canvas controls for platform‑specific scenes. (aitum.tv) Self‑hosted multistreaming shifts load to the creator: it increases outbound upload and requires careful bitrate/resolution matching to satisfy platform "quality parity" guidance and avoid a degraded Twitch experience. (streamups.com) Adoption is visible in tooling and tutorials: the sorayuki obs‑multi‑rtmp repository has roughly 4,800+ GitHub stars and a steady stream of installation guides and YouTube walkthroughs published through 2025–26.
