why not just setting up github enterprise? i mean it's still an infra to take care but if you are willing to pay for it, you may as well? from my experience the other git forge doesnt provide the same feature sets and api as github, like gitlab ci is actually pretty limited compared to GHA, there is no concept of github apps for other providers too, but maybe you just want a code hosting..
I replaced my custom nightmare of nixos on rpi5 (too much disk space used, too much IO used for raspberry) to a raspbian+arm+homebrew and i could not be happier
gh-poi plugin is a must if you manage a lot of github pr and want to easily clean the branch attached to it when pr is merged https://github.com/seachicken/gh-poi
no offense but a lot of those script are pretty hacky they may work for the user but i would not use them without making sure to review them and adapt them to my workflow
happy freshrss user here, the mobile web interface is a bit annoying, readera is fine. but it's so fast compared to use other things... (hosted on a old rpi3)
