Guilty as charged: https://github.com/drzel/vim-repo-edit

Above only works on vim. But has the advantage of working within vim, so no need to open a new instance, and with no external dependencies beyond git.

All three spin-offs (git-peek, git-peak, vim-repo-edit) work with any git repo, maintaining the decentralised nature of git

This latest one (repo-peek) explicitly only works with github and gitlab
