Just to contrast with some of the other comments regarding this, i’ve have a pretty good experience with this. Was fairly simple to setup up some docker-based runnings following their admin guidance. Have set up a couple (One for Codeberg, one for my own Forgejo instance) each via a seperate LXC container on my home lab. Has been relatively simple to administer so far.

The actions format may take some getting used to if not familiar with GitHub’s own actions CI, which if closely emulates, but most of my projects were coming from GitHub anyway.

Just be aware that, while it’s marketed as open source, from my last look into the project the open part relied on non-open licensing/code. More details in my blogpost here. Might not matter to some, but might matter if being open source is an important factor.
