JDownloader2 is an open source alternative and I cannot imagine using anything else (there are too many features). And I'm saying that as a python developer.
However, it truly is the most powerful download manager I’ve found. Combined with multi part downloads, I can easily max out my internet speed.
That's because it's not in fact open source. From Wikipedia:
> Some parts, but not all, of JDownloader are open-source.
> Mid-2012 there were complaints that JDownloader's installer added adware without the user's consent.[4] The JDownloader installation contains adware according to several sources, including the developer's own forums.[5][6] There were further complaints mid-2014.
JD is basically junkware. There's a reason why it doesn't seem to be packaged on any Linux distribution. It's not community-focused OSS in the ordinary sense.
SVN repo: https://svn.jdownloader.org/projects/jd
there's also mirrors on Github: https://github.com/mirror/jdownloader
I'm not sure which parts are not open-source
The lifetime option is less than $20 for either windows or Mac.
Mipony and jd shouldn't be compared with IDM. They don't do the same thing.
Mipony's reason for being is downloading from file sharing sites like MediaFire, mega, zippyshare, nitroflare...
If you don't download from file sharing sites, mipony is useless for you.
For torrents, a dedicated torrent downloader would be better suited to the task.
I'm however finding JD's ability to download YouTube videos quite useful, better than paid YouTube downloaders.
You'll need to edit the option string to the path you want it to save videos to. I have it set to not download playlists, but you can do whatever you please with the option string.
Just copy the youtube url, mouseover the input field(it will grab the url from the clipboard, and press the get file button. No frills but it works fine for my needs.
