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.
I have MeTube running, it does not what OP wants (unless he reconsidered) because it downloads the files to server storage.
But you can just start the container on his PC, then the Server is his PC?
Sure but then you can just start yt-dlp itself, with a GUI, no need to install a docker environment…
Cross platform https://github.com/dsymbol/yt-dlp-gui
Sure
So, you’re saying the link I posted actually does do what the OP wants?
