- Scene hotkeys, and your vertical canvas
Nothing fails in silence.
Every stage names itself when it struggles, and your recording does not depend on the network.
Every stage has its light.
Your recording survives the crash.
Messages as the app writes them. Names and figures are examples.
Ready-made packs, included.
Ten packs in 33 looks, with every screen of a stream: opening, game, talking, break, ending and alerts.

Is BriseStream free?
Yes, free and open source under GPL-3.0-or-later. Only the custom packs from the studio are paid, and they are optional.
When can I download it?
Version 1.0 is in preparation and there is no public build yet. The download page says what to expect and how to be told.
Is it really lighter than OBS?
The installer is much smaller. On your game, we measure and publish the cost with its conditions, and the 1 % target is not met everywhere yet. Read the numbers before you believe anyone, including us.
Can I keep my OBS scenes?
Yes: OBS scene collections import, and the local API speaks obs-websocket 5. How it works.
Which systems and graphics cards?
Windows first, then Linux and macOS. NVIDIA (NVENC), AMD (AMF) and Intel (QuickSync) video encoders, with a software fallback when a card has none.
Free, open source, for every streamer.
Version 1.0 is in preparation. Watch the project to hear when the first build ships.
