Forgejo has auto mirroring built in, it’ll periodically sync the repos you add. The disadvantage is you have to add them manually. Initially I wanted a list of my started github repos synced to my forgejo instance and just added them one by one. A simple cron job might be enough to do that, but last time I checked github didn’t have an API for fetching started repositories.

Mainly use it as a documentation search for APIs I’m not familiar with, or when I’m not sure what options there are to approach a problem. I work with unreal engine a lot, so I’d get a few pointers from an LLM first, then go read the source code of those APIs and inplement the rest myself.
