StreamTranslate
OBS Translation
Real-time translated subtitles in OBS via browser source. No plugin install, no GPU overhead, no breaks on OBS updates. 30+ languages, under 2-second latency.
30+ languages • Under 2s latency • No OBS plugin required
Adding real-time translation to OBS is a two-minute setup with StreamTranslate. No plugin to install — it works as a browser source URL that you paste directly into your OBS scene. Your viewers read translated subtitles in their language while you stream normally in yours.
Why OBS Translation Plugins Fall Short
Most OBS translation solutions require a plugin — LocalVocal, Polyglot, CloudVocal. Plugins break when OBS updates, require manual reinstalls, and add load to your local CPU or GPU. They also require you to run a model locally, which means performance depends on your streaming PC's specs.
StreamTranslate is entirely cloud-based. The translation happens on our servers, not yours. The output is delivered to OBS via a browser source URL. No plugin, no installation, zero GPU usage on your machine. Works on every OBS version from 26 onward.
