They can, but it’s not trivial. The challenge uses a bunch of modern browser features that these scrapers don’t use, regarding metadata and compression and a few other things. Things that are annoying to implement and not worth the effort. Check the recent discussion on lobste.rs if you’re interested in the exact details.

That’s… a very good idea. I should do that anyway.

Forgejo for projects and syncthing for data is probably perfect, thank you!

it does! I use it to sync my music, but I feel like it’s not the right tool for the job here.

I don’t want to “have the folders connected”, I want to have the ability to sync files easily, while excluding specific folders and files.

I have. It hasn’t worked very well for me, the docs weren’t great (though I’m looking at them now and they do seem better?) and it broke in strange ways.
