If you post a link to this, then I click that link, I am unable to reply directly, since I am on lemmy.world. I would need to first track down the equivalent post in my instance to reply. SSO solves this
This works great for apps. But I want to use the web interface to post a reply to content that’s not on my home instance. I can’t do that easily.
Codeberg only allows open source licensed code. If you’re working on non-free software you could self host Codeberg’s underlying software, or SourceHut is a different but other good option too.
