OBS Multiple RTMP Outputs review
A focused, free OBS add-on for synchronized multistreaming with per-output controls.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
OBS Multiple RTMP Outputs is a free, GPL-licensed OBS Studio plugin for creators who want to broadcast to several streaming sites at the same time. It is aimed at solo creators and small teams, including VTubers, who already work in OBS and need synchronized control over multiple streaming targets. The plugin adds a dock for adding, editing, reordering, starting, and stopping outputs, while retaining OBS as the main production environment.
Its strongest feature is per-output control. Each configured destination can have its own video resolution, frame rate, video encoder, audio encoder, OBS scene, audio mixer, and audio tracks. Outputs can start or stop together, synchronize with OBS, and reuse OBS streaming or recording encoders. Custom RTMP support makes the tool suitable for destinations that accept configurable streaming endpoints. Official builds cover Windows, macOS, and Linux, but compatibility is tied to OBS Studio versions, so choosing the correct build is part of setup and maintenance.
The product stays deliberately narrow. It handles multi-output management rather than providing a browser-based studio, scheduling, recording, chat, or broader integrations. Support is centered on documentation and community channels, and deployment is desktop-based. Choose it if OBS is already central to your workflow and simultaneous streaming with independent output settings is the main requirement. Choose an alternative if you need an all-in-one live production workspace, integrated audience tools, or a wider platform ecosystem beyond OBS and configured RTMP targets.
