ЮБуст is a free Chrome add-on designed to enhance the YouTube experience by improving video loading speeds and quality. It allows users to bypass restrictions and enjoy seamless streaming of 4K videos, live streams, and shorts without interruptions. With a straightforward one-click activation, users can access a free trial for seven days to test the service.

The program addresses common issues faced by YouTube viewers, such as buffering and reduced video quality. Without ЮБуст, users may experience long loading times, video quality dropping to 360p, and interruptions during live streams. With ЮБуст enabled, videos start instantly, maintaining high resolutions like 4K and 1440p, and providing a smooth viewing experience that includes uninterrupted streaming and effortless scrolling through shorts.
