If you know GitHub actions then you’ll immediately understand Forgejo actions. It was designed that way intentionally. There are some differences, but at least for me not enough to warrant any pitchforks.

If you have advanced use cases you might be more frustrated, but I’m not aware of any off the top of my head. I think my biggest complaint is that they haven’t exposed action logs over the API, so I can’t build tooling around them at the CLI level, feed them to an LLM, or more quickly diagnose problems that arise without using the website.
