I wanted to point out the different "levels" between your own local git repo and GitLab/GitHub. If you're by yourself, a local git repo is great. "One step up," would be a remote git repo you push/pull to (people often use this for encrypted password repos or dotfiles). After that are things like Gitea or Gogs, which add a lightweight web interface. As you move to GitLab/GitHub you start to see features like; accounts, permissions, code search, issues, wiki, pull request, CI integration, etc.

You can use something like GitHub/GitLab for most all of these tasks, but it's a bit overkill on things like maintenance and hardware requirements if your needs aren't great.
