• Streamlabs OBS – Built on OBS, with integrated widgets, alerts, and themes. Linux support is limited compared to OBS Studio.
• vMix – Windows-only, professional streaming software with advanced overlays and NDI support.
• Wirecast – Commercial alternative with multi-camera support; Linux users need Wine or VM.
