Today I made a research to find five awesome open source projects in Kotlin. You can install these apps and just use it, or you can browse the source code and learn how professionals code in Kotlin.

Today we will cover:

  • Seal
  • Clash for Android
  • ViMusic
  • CloudStream
  • UnCiv

Let’s dive in into today’s list:

Seal – YouTube video downloader

Downloading YouTube videos became very popular for multiple reasons. For example, because some videos are available only there. Secondly, people want to be able to play the videos in the future. It is not always possible on YouTube. People delete accounts, copyright owners and fake owners take down videos. So it is understandable people do it. Especially, since doing it via YouTube is possible, AFAIK, only after paying to YouTube.

Seal is a powerful app written in Kotlin that allows you to download videos with embedded subtitles, download audio from videos, download whole playlists. It is a great tool for those of you, who want to enjoy the off grid video experience.

Just remember to consult your local law and make sure you don’t hurt video authors for example, by uploading videos on public platforms without their permission. I am earning 2 dollars from over 300 videos so please think about me!

I am using the app to download my own videos from YouTube. Seal is a great tool for youtubers and video downloaders.
