SourceHut

Sourcehut (styled as sr.ht by its official hosted instance or its name in lowercase or the letters S and H being capitalized) is a free and open source code forge, created by Drew DeVault, and is currently in public alpha since November 2018, alongside its public instance.

Some of the differences between sourcehut and GitLab other than licensing on source side is that most of its services are usable without JavaScript being enabled and its emphasis on the Git + email workflow instead of JS-backed web UI as seen on GitLab (per the Debian wiki for Salsa, you could hack around the API or use  CLI).

Usage of sourcehut within the org
We use sourcehut to host our mailing lists and issue trackers, and host git mirrors of our different projects. We also use it to host wikis and manuals with just Markdown and Git without the pain of managing yet another Miraheze wiki. The table below lists the services that we use in different stages.
