OBS is the default for free streaming and local recording; for heavy editing you need a dedicated app alongside it.
About
In practice. What you can do with OBS.
OBS Studio (Open Broadcaster Software) is the reference open-source software to capture your screen, webcam, and broadcast live to Twitch, YouTube, or any other service, or record locally. Free and watermark-free, it's the default choice for most streamers and tutorial video creators.
Its learning curve is steeper than simplified commercial tools (Streamlabs), but its flexibility (scenes, sources, plugins) makes it the reference tool once production needs become a bit more sophisticated.
