I don't know how many Darktable users there are on ModelFolio. But if you intend to visit Darktable's site, then you'll find it's off-line. In fact, it's been down for the last few days. I don't know why it's down, but according to its Mastadon page, its engineers are working the problem.
Meantime, MacOS and MS Windows users wanting to download a copy can still do so directly from Darktable's GitHub:-
GNU/Linux users are mostly unaffected because binaries and source packages should be in your distro's repository anyway. And the source code is available from its GitHub too.
