For Darcs I have been using darcs hub & mirroring to my server. That said Smederee has slowly but surely been shaping up to be a better replacement (recently got reStructureText support!); once they have obliterate support, I will be tempted to make it primary for real since it covers all the basics.

For Pijul, I can really only use it self-hosted over SSH. Nest is far too feature barren to be usable—especially without the ability to fetch tarballs for instance where you can’t have or use the pijul binary for fetching (which is a bit ironic since the Pijul binary has an archive to create tarballs, Nest just doesn’t expose it). Pijul is faster & the key concept of separating your commit ID from details (such as Darcs or Git using Name <e@mail.address> as the identifier) is much nicer not just for privacy if wanted but changing these details for whatever your reasons maybe (imagine changing your name after marriage or sex change & trying to convince all projects you’ve committed to to rewrite their history with your new info to not be confused or dead-named—most maintainers would ignore you). Someone should write a decent, lightweight forge so Pijul can be usable.

If using Git, an inferior VCS IMO, things are now going hosted on Codeberg. In the past, I had paid for SourceHut & while it was a generally nice, lightweight experience I was disappointed with the features & progress to the point I didn’t feel I was getting good value. Since I don’t write any of my own code using Git anymore, I don’t really bother self-hosting cgit or something.
