• NewPipe has a clean and modern user interface designed for mobile devices.
• NewPipe is open-source and available on F-Droid, providing a privacy-focused alternative to the official YouTube app.

Cons of NewPipe

• NewPipe may not have the same level of feature parity as the official YouTube app, particularly for advanced functionality.
• NewPipe's development is community-driven, which can lead to slower updates and bug fixes compared to a commercial product.
• NewPipe's reliance on unofficial YouTube APIs may result in compatibility issues or service disruptions over time.

Code Comparison

YouTube-Viewer:

def get_video_info(self, video_id):
    """
    Retrieve video information for the given video ID.
    """
    url = f"https://www.youtube.com/watch?v={video_id}"
    response = self.session.get(url)

    author = soup.find("span", {"class": "yt-user-info"}).text.strip()
    # Additional metadata extraction...

NewPipe:

Pros of Invidious

• Invidious provides a privacy-focused alternative to the official YouTube website, allowing users to access YouTube content without being tracked by Google.
• Invidious offers a clean and minimalist user interface, which can be more appealing to some users compared to the cluttered design of the official YouTube website.
• Invidious supports a wide range of features, including the ability to download videos, adjust playback speed, and customize the appearance of the website.

Cons of Invidious

• Invidious may not have the same level of feature parity as the official YouTube website, as it is a third-party project.
• Invidious may not be as widely known or used as the official YouTube website, which could make it less convenient for some users.
• Invidious may be subject to more frequent downtime or service disruptions compared to the official YouTube website, as it is a smaller and less-resourced project.

Code Comparison

Here's a brief code comparison between Invidious and YouTube Viewer:

Invidious (Ruby):

get '/api/v1/videos/:id' do
  video = Video.find_by(id: params[:id])
  if video
    json video.as_json(only: [:id, :title, :author, :length_seconds, :published, :thumbnail_url, :view_count])
  else
    status 404
    json error: 'Video not found'
  end
end

YouTube Viewer (Perl):

sub get_video_info {
    my ($self, $video_id) = @_;
    my $url = "https://www.youtube.com/get_video_info?video_id=$video_id";
    my $response = $self->ua->get($url);
    if ($response->is_success) {
        my $info = parse_query_string($response->content);
        return $info;
    } else {
        return undef;
    }
}

Both code snippets demonstrate how the respective projects handle the retrieval of video information, but the implementation details differ due to the different programming languages used (Ruby for Invidious, Perl for YouTube Viewer).
