In the same order you asked:

Safe, easy to use, polished and reliable ; Someone else tried to emulate the first one success ; Poorly executed open-source alternative you can selfhost.

All of them speak the git and are essentially web UIs made to manage it and the creation of repositories and setting up permissions.

Instead of wasting time on supporting bullshit hardware that almost nobody owns and will be forgotten in about 6 months, what about placing some effort into real hardware that real people want to use like tablets? Fucks sake.

Update: just to make it clear, I own no hardware of that type, it’s not “doesn’t work on my hardware” type of situation. It is that everyone likes to talks about Linux desktop (including Canonical) yet nobody puts any effort into going into the tablet market that is where Linux can have a real advantage (because ARM + full desktop OS experience) and get a real user base.
