This repository has been made in an attempt to host a Chromecast server for myself, but it failed terribly because I don't know how to code properly 💀 and because the Chromecast library isn't very open source :( (I switched to using Kodi now)
Can I use it?
You can try to use it, or even revive it, but it probably won't work as it didn't work for me.
What services does it support?
It was meant to support the entirety of the Chromecast features, but it only ended up supporting YouTube because of the closed nature of Chromecast.
