You have a similar project for Android called Libretube :) Here’s a list of projects that use Piped’s API: https://github.com/TeamPiped/Piped#made-with-piped

I currently host the official instance, which is entirely run by donations. However, there are many community instances people can switch to in the preferences menu on the site. They are listed at https://github.com/TeamPiped/Piped/wiki/Instances

Hello there, I’m the author of Piped and would love to answer any questions you may have! 👋
