I’ve been running codex’s remote app server as a systemd service for the last several months, and before that opencode remote. It’s very easy to switch between my phone and desktop app.
I haven’t tried herdr yet, but maybe it’s just not targeted at me?
The real problem I have with the remote codex setup is when it needs to authenticate as me. I sort of solved this for sudo and ssh with this [1], but I think something like this could be integrated deeper into the harness
