Any standalone analogue of Cent's video grabber?

2. Browser must be running while download proceeds.

this is wrong
cent uses yt-dlp to download, and it does not stop the download even if you click cancel (this is a bug), and even more so if the browser closes
and you can use it separately from the folder \User Data\MiscTools by running it in cmd, it will work much better
also in the new version of the browser, a call to cmd is available in bookmarks as a bookmarklet, with the transfer of a link

Code:

cmd://yt-dlp -o "~\Desktop\%(title)s.%(ext)s" --add-header "User-Agent:{USER_AGENT}" --add-header "Cookie:{COOKIES}" {URL}

Cent uses exactly the same call string
just not just a URL, but also direct links if the site is not supported by yt-dlp for indirect links

also cent launches two yt-dlp processes even after the browser closes, these two processes do not close and continue to hang in the task manager
