The big difference is that we link the source code to the video. So you can click on the code and watch exactly when the developer wrote it. We are also making it work directly from the IDE and GitDuck is 100% for developers.
Not the full experience, you couldn't select/fork/interact with the code. In Twitch/YouTube the watching experience is linear (you watch a video from start to the end). In GD the code defines what part of the video to be played.
