There is also Trae created by bytedance

I am using the default mp4 and webm file format to download the music.

It depends, if the software is written and controlled by Chinese then it’s fine. I would gladly use anything written by say Bytedance

Why do you want to host it at all? I mean there are already a ton of fediverse servers out there you can tell Indian people to use one of those. also hosting is expensive unless you have a very good reason to do so
