I also self-hosted GitLab for some years, eventually ended up moving over to Gitea + WoodpeckerCI + Nexus (with Nexus for a while). Well there was DroneCI in the middle for a bit there as well, but Woodpecker is perfectly okay and more free in regards to what you can do. Only thing is that not that much other software out there supports Gitea, for example Kepler only knows about GitHub, GitLab, Jira, Trello and Linear.
