yt-dlp isn’t complex at all if you’re just downloading videos, it just this: yt-dlp https://link.to/the_video. That’s only for Windows though. For iOS, you could try cobalt.tools, but that only supports certain cites, and I’m not sure if Nebula is supported. Any other web-based downloaders shouldn’t be trusted
