All the downloaders that I find only downloads to the server and I only want a UI without ads to make easies to use yt-dlp without the terminal.
Just start a yt-dlp frontend on that machine that should have the files in the first place?
“Just download an YT downloader application” is not what OP was asking for.
I too have been looking for a centralized YT-DLP frontend that I can use to either 1. Store vids on my server 2. Give me (or more importantly, my wife) a prompt to download them.
Metube can do that, but that’s also not what OP asked for since he does NOT want to store the files on the server.
This MeTube in a local docker container seems to do what OP wants:

tag /u/kutu-dev
this could be what you’re looking for.

Might be technically possible with WASM nowadays.
Jdownloader
So why put the UI on the server and not in the client??
