You can code locally, push to a repository, and have the changes almost instantly on your server ready to be run.

yes, i prefer to save those 10 seconds as I do that a thousand times a day

There are solutions to mount the remote filesystem locally and use any regular code editor

And most of them either rely on SSH+rsync, syncthing, or something along those lines - in other words, tools that will sync the files reliably, even on bad links...eventually. Never have I seen a backend that's built for editing...the remote-mount abstraction mostly works, but leaks specifically in these edge cases.

There are also editors that can use a plenty of various protocols to read & save remote files while performing editing locally.
