Ok I just googled startpaged it and oh boy it is FOSS but the UI man it looks like a smartphone app from android 4.4 era but the devs are working on a full overhaul so I'll wait and see
There is also FileCxx.
I will look into it, seems interesting
There is nothing that will work as simple as IDM
I strongly agree but from my experience FDM seems the closest to it and FDM is not as simple as IDM, I wish if there is a native linux version.
especially with that little floating button on top of videos it detects, with all available frame resolutions.
Damn right man, it is so damn good, can't anyone else copy it please???
For video sites, I use yt-dlp. For galleries, gallery-dl.
I know of yt-dl but never heard of dlp before well until yesterday and for gallery-dl the name alone is very intriguing, I will definitely take a look at it, thanks for mentioning it!
For anime sites, I just log into Windows and use IDM.
