WinDLP
A deliberately simple Windows GUI over yt-dlp — paste a URL, pick video or audio, get a playable file.
yt-dlp is excellent and entirely a command-line tool. That’s a wall for anyone who
doesn’t live in a terminal.
WinDLP is the smallest thing that gets over it: paste a URL, choose MP4 or MP3, and it downloads and converts to something that will actually play. Whole-playlist downloading is in as an experimental option.
Deliberately not a front-end for every flag yt-dlp has — the point is that someone who
would never open a terminal can use it.
