Not affiliated with them, but this lets you view Claude Code, OpenCode and I guess other harnesses like Codex in the same session https://paseo.sh/

I didn't really care about their mobile app and the worst experiences were sometimes the sub-agents within OpenCode freezing and refusing to report their status (though this also happened with Kepler by the GitKraken folks).

I created Circus Chief to solve this (and other) problems. Use whatever providers you want with it.

Roll your own harness or use an open source harness with a Codex subscription.

I maintain a Claude subscription for Fable but seldom use it.
