I’ve heard the main two suggestions are Codeberg and Gitlab. However, there has been some mixed feelings about GitLab I’ve seen across the internet in regards to them being as FOSS as Bitwarden is with their “Open-Core” model. With Codeberg though, there was a recent major security issue.
I would just be curious to get other people’s thoughts throughout the community, and then I can decide where I want to migrate my repos.
Whatever the solution behind is, if you have the resources, move to something self-hosted. Open core or not, if that topic matters to you, you might need something you can own and control. BTW, have a look on Forgejo, Codeberg and Gitea: these are the solutions I see when people look for something FLOSS, not open core, and maybe self-hostable.
