Performance First
A Rust core, profiled against a live game until it disappeared into the background. 1.8% CPU is a promise, not a peak.
Our story
streamerOS started as a complaint. We were streamers before we were builders — and every night, the same two problems. Our “lightweight” broadcast tools quietly ate CPU until a clutch moment turned into a stutter. And the best beats of the stream — the raid, the comeback, the chat going feral — slipped past while we fumbled for a scene hotkey.
So we built the tool we wanted. A Rust core, measured obsessively, that holds a 1.8% CPU footprint under a live game. An automation engine — the Auto-Hype Director — that watches chat velocity and sentiment and switches scenes the instant the room peaks. And an architecture that is local-first by construction: your chat, your audio, your audience never leave your machine.
streamerOS is open-source and free, because the people who go live every night deserve tools built with the same care they put into their broadcast — and because the surest way to earn a streamer’s trust is to let them read every line.

Local-first isn’t a setting — it’s the architecture. No server, ours or anyone else’s, ever sees your chat or your audio.
The Auto-Hype Director reads the room so you don’t have to. Your scenes follow your stream’s energy, automatically.
