I'm really bad at keeping my dependencies up-to-date manually, so dependabot was great for me. I don't use github anymore though, and I haven't really been able to find a good alternative.

I found Snyk, which seems to do that, but they only allow logging in with 3rd party providers which I'm not a big fan of.

Edit: seems like Snyk also only supports a few git hosts, and Codeberg isn't one of them.
