What is OBS?
Open Broadcaster Software — a popular, open-source application for live streaming and recording. Used by most Twitch streamers.
OBS (Open Broadcaster Software) is the most widely used streaming application on Twitch. It's open-source and handles video/audio capture, scene management, encoding, and broadcasting to Twitch, YouTube, and other platforms.
While OBS setup is important for stream quality, the biggest growth bottleneck for small streamers is discoverability, not production quality. Get your OBS basics right, then invest your time in networking.
