I’m still learning. I have a github account, many gitlab accounts, a gitlab.com account and my own forgejo.
I managed to clone most stuff to my own forge but managing issues is still a pain on so many platforms, for me at least.
Easiest would be one frontend where I can just combine issues over all my accounts.
Is there a straightforward way I just havent found yet?
No, there is not.
Mirroring git repos themselves can work with automation. Anything beyond that has serious drawbacks or complexity or won’t work.
As for your key auth (git client auth), one key for authentication is sufficient to use across all platforms.
Okay! Thanks! :)
