Upstreamer is a thin layer that sits on top of any YouTube or Vimeo stream and which adds real-time interaction for your audience and customisable layout, stages and announcements. Users can click to add emojis or write comments that slide through the screen.

Hello Product Hunt! During the lockdown, I and a group of EPFL students organised The Curve, an online music festival to raise funds towards Coronavirus research. We developed a custom platform to enable live, fun interaction during the event. Today, I'm releasing this platform on its own, named Upstreamer, for any broadcaster or event organiser. Using Upstreamer, you can also add branding, donation forms, or any HTML on top of your stream; or even let your viewers watch multiple of your streams at a time, like in a music festival where you would move between different stages. Looking forward to getting your feedback, and hopefully we can get in touch! 😄👋
