html5syt Casual opportunity I found that GitHub Actions can run Composer, can execute the shell command, there are several hosts that are all configured, and have Ubuntu, windows, mac host.just I don't know how to write code(Refer to https://docs.flarum.org/composer#i-dont-have-ssh-access, github actions has ready market)
luceos Yeah this is possible. It's called ci/cd. You can make the workflow install all the dependencies inside GitHub actions for the php version on your server and then copy all those files over to your server using ftp or SCP or similar.
