Managing multiple Git remotes lets you push code to different destinations simultaneously — maintaining mirrors on GitHub and GitLab, working with both origin and upstream in open-source projects, and deploying to different environments from the same repository. As the creator of CoreUI with 25 years of open-source development experience, I maintain multiple remotes in every major project: the canonical repository, contributor forks, and deployment targets. The commands are simple — git remote add, git remote set-url, and git push --all — but understanding when to use each pattern makes a significant difference in team workflows. You can have as many remotes as needed; there is no Git limit.
